Semiconductor Equipment & Cleanroom Factory in Selangor 2026: Who Needs What, and Where
NXP is expanding in Petaling Jaya and Neways builds ASML modules in Selangor. Here is which semiconductor suppliers need which factory, the cleanroom-ready specs to check, and where to look.
Key Takeaways
- Selangor's semiconductor growth is mostly chip design plus a few large back-end expansions. It is not a wafer fab or mass-OSAT cluster.
- IC design firms in Puchong and Cyberjaya need offices and labs. Factory demand comes from equipment-module makers, EMS and PCBA lines, precision suppliers and cleanroom contractors.
- NXP is adding about 500,000 sq ft in Petaling Jaya, with its production ramp from the first quarter of 2028. Suppliers who want to be nearby should start searching in 2027.
- "Cleanroom-ready" is a shell question: power, slab, roof height, exhaust and gas storage. Your customer and cleanroom contractor set the ISO class.
- Rent while volumes depend on customer qualification. Buy or lease long when fit-out costs more than a few years of rent.
What is actually happening in Selangor
At the national level, the National Semiconductor Strategy launched in May 2024 targets RM500 billion of investment by 2030 and 60,000 skilled local engineers. The government has set aside RM25 billion in fiscal support for it. Selangor's share has not been published, so read it as direction, not a demand forecast.
What Selangor has done is visible and specific:
- Design parks. IC Design Park 1 opened in August 2024 at PFCC, Puchong, on just 0.6 hectares. IC Design Park 2 followed in Cyberjaya in November 2025, together with an RM100 million fund for chip-design startups. By April 2026 the parks had 302 engineers hired against a target of 400 for end-2026, across 15 active companies.
- A large back-end expansion. On 12 August 2026 NXP broke ground on an expansion of its assembly and test site in Petaling Jaya. It adds about 500,000 sq ft of production space, taking the site to around 900,000 sq ft. Output is expected to more than double, with the production ramp from the first quarter of 2028.
- An equipment-module maker for ASML. Dutch firm Neways opened its first Southeast Asian plant in Selangor in May 2025. It builds high-level semiconductor equipment assemblies with ASML as launch customer and plans more than 200 staff. It was the first company through Invest Selangor's Soft Landing programme.
- A local cleanroom contractor scaling up. Sum Technology, based in Petaling Jaya, builds cleanrooms and mission-critical M&E systems. Its IPO public portion was oversubscribed 110.54 times. Its prospectus shows a Jenjarom factory being renovated to operate by the third quarter of 2026, plus a rented semi-D factory in Banting next to it.
- Fresh money. Budget 2027, tabled on 9 October 2026, includes a RM1.2 billion Khazanah and KWAP package to move local semiconductor firms up the value chain, with a Selangor semiconductor fund inside it.

Who in the chain needs which premises
A common mistake is asking for a "semiconductor factory" when the business needs something simpler, or the reverse. Start with your role in the chain.
| Role | Typical premises | Key spec | Where to look first |
|---|---|---|---|
| IC design house | Office and lab, not a factory | Fibre, secure lab rooms, test equipment power | Puchong, Cyberjaya (design parks) |
| Equipment module or subsystem maker | Detached or large semi-D factory | Cleanroom-convertible zone, crane, clean assembly bay, strong office | Shah Alam, Petaling Jaya, Puchong, Kota Kemuning |
| EMS and PCBA | Semi-D or detached factory | Stable power, ESD-controlled floor, air-conditioned production hall | Shah Alam, Puchong, Bangi |
| Supplier to OSAT (precision parts, trays, tooling, consumables) | Semi-D or detached factory | High power for CNC, floor loading, compressed air | Shah Alam, Kota Kemuning, Bangi |
| Cleanroom and M&E contractor | Workshop plus warehouse | Fabrication space, crane, yard, panel and duct storage | Jenjarom, Banting, Puchong, Shah Alam |
| MNC back-end plant | Own land, expansion on existing site | Built to order | Usually not a market search |
MNC plants rarely buy on the open market. The factory demand they create sits one level down, with their module, parts and service suppliers.
The spec sheet: what "cleanroom-ready" means for a factory shell
"Suitable for cleanroom" means nothing unless the shell supports the cleanroom your customer will audit. The class itself is set by your customer's process and confirmed with a specialist cleanroom contractor. For reference, one EPCC contractor describes OSAT cleanrooms as typically Class 10 to Class 100K. Your job in the property search is to make sure the building does not block that design.
| Item | What to check | Why it matters |
|---|---|---|
| Cleanroom-convertible shell | Clear zone free of awkward columns, height for a ceiling plenum | Plenum and ducts eat height |
| Power supply | Existing amperage and kVA, TNB substation on site or nearby, room for upgrade | HVAC for cleanrooms runs 24 hours and is power heavy |
| Redundancy | Space for a generator set and UPS room, dual feed if available | A power trip can scrap work in progress |
| Slab and vibration | Slab thickness, floor loading, distance from heavy traffic and presses | Precision assembly is vibration sensitive |
| HVAC and exhaust | Roof strength for AHUs and fans, room for exhaust stacks and scrubbers | Fit-out cost rises sharply if the roof needs strengthening |
| Chemical and gas storage | Outdoor or separated area for gas cylinders and chemicals, bunded storage | Check with Bomba and DOE what your specific materials require |
| Two-storey office | Engineering, QA and audit rooms | Customers visit and audit |
| Loading | Dock or level loading, wide doors, crane for modules | Modules are large and fragile |
Before shortlisting, run your machine list through the factory power calculator and check your heaviest equipment with the floor loading calculator. Then search factories by specs to filter amperage, height and floor loading together.
Power removes most candidates, because many older factories were built for light assembly. If you need a high-power unit, including ones that owners have not advertised publicly, ask us for high-power factories in Selangor and give us your load estimate.
Selangor areas compared for semiconductor suppliers
Petaling Jaya. The NXP site is here and so is Sum Technology's base. Industrial stock is mature and scarce, usually older buildings needing M&E upgrades. Best for firms that must be minutes from a customer.
Puchong. Home to IC Design Park 1 and close to both PJ and Cyberjaya. A practical middle ground for EMS, test and module firms that want engineers from the design ecosystem. Browse factories for rent in Puchong to see current stock.
Shah Alam. A large pool of detached and semi-D factories, so more choice of power supply and building size. See factories for sale in Shah Alam. Older sections need careful power and roof checks; newer parks are easier to convert.
Kota Kemuning. Next to Shah Alam, with generally newer semi-D and detached stock suited to mid-size module and precision suppliers.
Bangi. Established industrial areas within reach of Cyberjaya. Suits EMS, PCBA and parts suppliers that do not need to sit near PJ.
Cyberjaya fringe. Cyberjaya itself is mostly offices and data centres; industrial options sit on its edges toward Dengkil and Puchong.
Jenjarom and Banting. The Sum Technology pattern: a contractor serving semiconductor and data centre clients chose southern Kuala Langat for workshop and storage space. See also our data centre supplier factory guide.
Penang and Kedah remain the choice for fabs and large OSAT lines; this guide is about Selangor's module, EMS and supplier tier.
Risk check: tariffs and timing
On 15 January 2026 the US imposed a 25% Section 232 tariff on a narrow category of advanced AI chips, with broad exemptions, and signalled that a wider semiconductor tariff could follow. ISEAS also describes the current scope as narrow with a wide range of exemptions. If your customers ship to the US, use lease structure as a hedge: a shorter first term with renewal options, or a break clause.
Timing is the other risk. Suppliers usually win volume only after customer qualification, so if your plant must be audited before NXP's 2028 ramp, a search starting in mid-2027 is late once cleanroom fit-out is added.
Practical checklist before you sign
- Write down your role in the chain and the cleanroom class your customer requires, confirmed by a cleanroom contractor.
- Calculate your total load, including cleanroom HVAC running 24 hours, and compare it with the unit's current amperage and kVA.
- Ask whether a TNB substation is on site and whether the supply can be upgraded, and by when.
- Get the slab thickness and floor loading rating in writing.
- Check roof structure and internal clear height for AHUs, ducting and a ceiling plenum.
- Confirm space for a generator set, UPS room, gas cylinders and chemical storage.
- Check with Bomba, DOE and the local council what your process and materials require before committing.
- Confirm industrial title and CCC. In a tenancy, get written consent for M&E works and agree cleanroom reinstatement terms.
Rent or buy?
Rent if your volumes depend on a customer qualification that has not happened yet, or if your fit-out is modest (ESD floor, air-conditioning, simple clean zone). Negotiate a rent-free fit-out period and a renewal option long enough to recover your M&E spend.
Buy if your cleanroom and M&E fit-out costs more than several years of rent, if you must strengthen the roof or upgrade power, or if your customer expects a long-term site. The upgrade then adds value to your own asset.
A long lease with an option to purchase keeps cash for equipment while protecting the fit-out. Browse high-power factories for rent in Selangor to compare what is on the market today.
FAQ
Does an IC design company in Selangor need a factory?
Usually not. Design houses need offices, labs and test benches, which is what the IC Design Parks in Puchong and Cyberjaya provide. A factory makes sense once you add assembly, testing or equipment work.
Can any factory be converted into a cleanroom?
Only if the shell allows it: enough height for a ceiling plenum, a roof that can carry HVAC equipment, power for 24-hour air handling, and space for exhaust and gas storage. Ask a cleanroom contractor to inspect before you sign.
Which ISO class should I plan for?
That depends on your process and your customer's audit requirements, so confirm it with a cleanroom contractor. The class drives HVAC power and ceiling height, so settle it before you shortlist.
Is Petaling Jaya the best area if I supply NXP?
Being close helps with deliveries and engineering visits, but PJ industrial stock is limited and mostly older. Puchong, Shah Alam and Kota Kemuning are a reasonable drive away with more choice.
How does the Section 232 tariff affect my factory decision?
The January 2026 US tariff covers a narrow range of advanced chips, but a broader tariff has been signalled. If your products end up in US-bound goods, keep your lease flexible until demand is clear.
How early should I start looking for a factory?
Add cleanroom design, approvals, fit-out and customer qualification to your search time. To be producing before NXP's 2028 ramp, start shortlisting in early 2027 at the latest.
