About
Twenty years of moving one step further up the part.
Advance Semiconductor started in 2004 making wafers. Then the ingot the wafers came from. Then the chamber parts machined out of it, the quartz around them, and eventually the service that keeps all of it running. Each step was a customer asking whether we could also do the next thing.
What we are building
A transparent ecosystem, not a catalogue.
Our stated mission is to develop a transparent ecosystem for the best customer experience, by building a cohesive network of parts, service and solutions. In practice that means one supplier can fabricate the part, clean it when it comes back, repair the component it sits in, and support the tool around it — without the customer managing the seams between four vendors.
Transparency is the harder half. It means telling you which grade we used, which cleaning method the job took, what the measurement actually read, and when we cannot do something.
History
How the business took its current shape.
-
2004
Established in Santa Clara
Founded producing silicon, sapphire, quartz and ceramic wafers, in the middle of the equipment cluster we still serve.
-
2008
Bi-directional silicon ingot manufacturing
Moved upstream from wafers into growing our own silicon.
-
2010
Casted mono ingot for semiconductor parts
Among the first to take mono-cast silicon into chamber consumables — the basis of the focus and edge ring business.
-
2012
Advanced materials fabrication, and equipment support
Added technical advanced materials fabrication alongside equipment performance support, with factories established in Binh Duong, Da Nang and Hue, Vietnam, working with the US sites.
-
2016
Custom field service response and repair
Field service formalised into a division, with response and repair scoped per customer rather than sold as a generic retainer.
-
2022
Parts, service and solutions as one network
The three lines brought together deliberately, so a customer can enter at any of them and use the others without re-qualifying a new supplier.
Footprint
US headquarters, Vietnamese production.
Engineering, wafer services and fast-turn work sit in Santa Clara. Volume quartz and silicon parts fabrication runs from the plant at VSIP, Vietnam. For customers under pressure to diversify away from a single-country supply chain, that structure is usually the reason the conversation starts.
Santa Clara, California
Machining, wafer substrates and services, engineering and customer-facing operations.
- Wafer products and services, 25–450 mm
- R&D and design-stage support
- Precision machining
- Inside the Bay Area equipment cluster
VSIP, Vietnam
Core quartz and silicon parts fabrication, with facilities at Binh Duong, Da Nang and Hue.
- Volume fused quartz fabrication
- Silicon parts machining
- Advanced ceramics
- Non-China Asian capacity
Also running: an equipment support division with thirty years of experience in tools and equipment support, and a refurbishment business covering harvesting from decommissioned tools plus pump and valve refurbishment.
Where we fit
Independent, and sized for the work most suppliers decline.
The silicon parts market is concentrated, and several of the larger suppliers are owned by equipment makers. If you build tools, that means handing drawings to a division of a competitor. We have no OEM parent.
We are also small enough that a fifty-piece order, a single replacement or a prototype gets the same process as volume production — which matters, because that is how qualification starts.
- No equipment-maker ownership and no competing product line
- US-headquartered with non-China Asian manufacturing
- Prototype and small-lot work quoted properly
- Parts, refurbishment and equipment support under one supplier number
- Copy Exact™ discipline once a part is qualified
Next step
Start with one part.
Most of our long-running customers began with a single replacement that needed to arrive quickly.
