Semiconductor
Semiconductor manufacturing demands high-purity materials, tight tolerances, and uncompromising precision. MWDT is a single-source partner for wafer fabrication equipment (WFE), gas and chemical delivery, vacuum and process chambers, and backend test and handling — pairing a core competence in stainless steel machining with technical ceramics, ceramic injection molding, and high-performance/ESD plastics under one roof.
Gas, Chemical & Vacuum Components
Our expertise machining all grades of stainless steel — a genuine core competence — covers the ultra-high-purity (UHP) and vacuum hardware at the heart of process equipment:
- Precision flanges, fittings, and face-seal hardware for UHP gas delivery
- Gas manifold blocks with complex internal passages, plus valve and regulator bodies
- Vacuum chamber components, liners, and feedthrough hardware
316/316L stainless is specified for its corrosion resistance to process chemistries; electropolishing and passivation — available through our affiliate Anodic Process Technologies — reduce particle adhesion and outgassing for UHP and vacuum service.
Technical Ceramics for the Process Chamber
Through ceramic injection molding and machining, MWDT produces the high-purity ceramic components that withstand plasma, heat, and wear inside the chamber:
High-purity alumina (Al₂O₃)
The workhorse insulator and structural ceramic — electrical insulation, plasma and wear resistance, and dimensional stability.
Aluminum nitride (AlN)
High thermal conductivity combined with electrical insulation — ideal for electrostatic chuck components, heaters, and antistatic handling parts.
Silicon carbide & silicon nitride
Hardness plus thermal-shock and plasma resistance for chamber parts, focus rings, and CMP components — along with molded nozzles and injector tubes for gas and plasma delivery.
ESD & High-Performance Plastics for Backend
For wafer handling, test, and backend assembly, MWDT machines static-dissipative and high-temperature engineered plastics:
- Static-dissipative (ESD-safe) plastics for wafer carriers, trays, end-effectors, handling jigs, and vacuum-wand tips that protect devices from electrostatic discharge
- ESD and carbon-filled PEEK and Celazole® (PBI) for test sockets and burn-in fixtures requiring dimensional stability under thermal cycling
- PTFE and PVDF for chemically inert, wetted parts in etch, clean, and CMP wet-process tools
- Advanced-material labyrinth seals for turbo-compressor (vacuum pump) equipment
Why MWDT for Semiconductor
The ability to machine stainless steel and specialty alloys, mold and machine technical ceramics, and produce ESD and high-performance plastics represents a broad range of capabilities that are rarely available from a single source. By expanding or strategically integrating these complementary capabilities — including 5-axis machining with cobot automation, engineering support, specialized finishing, and QuickTurn production — MWDT provides customers with a more streamlined, single-source solution. This expanded offering simplifies customer supply chains across both new equipment builds and recurring consumable components.
