PROCESS APPLICATIONS
Support Across Critical Semiconductor Processes
Etch
Etch environments often create replacement challenges around corrosive gas, chemical and plasma exposure, seal compatibility, material selection, and clean gas delivery hardware. CrestTec can review drawings, photos, samples, or part descriptions to support replacement, refurbishment, or component sourcing needs.
Common support includes
- Wet etch support components
- Dry etch gas delivery and chamber assemblies
- Corrosive gas service components
- Seals and gaskets
- Machined metal and plastic parts
- Valves and flow control components
- Cleaning or refurbishment
CrestTec can support etch-related requests without publishing OEM tool references or replacement part lists online.
Does CrestTec offer O-rings for corrosive etch environments that may help extend time between preventive maintenance cycles?
Yes. CrestTec supports high-performance O-ring materials designed for corrosive semiconductor etch environments, including materials selected for resistance to aggressive process chemistries, plasma exposure, and elevated temperatures. The right material can help reduce seal degradation, particle generation, and premature failure, which may extend component life and the time between preventive maintenance cycles.
Gas Delivery
Gas delivery environments require attention to fit, leak integrity, cleanliness, material compatibility, and corrosion resistance. CrestTec supports gas delivery hardware and related components used in high-purity semiconductor systems.
Common support includes
- Gas delivery weldments
- Gas sticks and manifolds
- Valves and MFCs
- Regulators, filter, purifiers, and fittings
- Sealing components and replacement hardware
- Refurbishment review for existing gas delivery assemblies
Common requests included replacement assemblies, hard-to-source components, refurbished weldments, and application-specific gas delivery hardware.
Does CrestTec design and manufacture gas delivery weldments for corrosive semiconductor environments?
CrestTec can support custom gas delivery weldments and assemblies designed for semiconductor process environments. Our team can review materials, geometry, surface requirements, corrosion concerns, and process conditions to recommend the right solution.
Deposition
Deposition applications may involve high-purity gas delivery, precursor delivery, purge paths, heated lines, MFC integration, sealing hardware, and documentation requirements. CrestTec supports component and assembly needs for CVD, PVD, ALD, and related deposition environments.
Maintaining uniform film quality and vacuum integrity in chemical and physical vapor deposition (CVD/PVD) requires components that can withstand extreme thermal and plasma environments. CrestTec provides precision replacement parts and advanced refurbishment services that extend the lifecycle of your critical deposition tools while significantly lowering your cost of ownership.

Common support includes
- Seals, O-rings, bonded doors/gates and pendulum valves
- High-purity gas lines
- MFC-integrated assemblies
- Gas distribution face and blocker plates
- Sealing hardware
- Valves, regulators, filters, and fittings
- Repair and refurbishment of ESCs, heater pedestals etc
For Deposition-related requests, CrestTec can review application details such as line configuration, volume sensitivity, purge behavior, material compatibility, and thermal conditions during RFQ.
Does CrestTec support bonded slit valve doors, gate valve seals, and pendulum valve seals?
Yes. CrestTec supports bonded slit valve doors, gate valve seals, pendulum valve seals, and other custom sealing components used in semiconductor vacuum and process equipment.
Implant
Ion implant applications can create demanding component requirements around vacuum integrity, material compatibility, particle control, thermal exposure, and repeatable system performance. CrestTec supports replacement and refurbishment needs for components and assemblies used in semiconductor implant equipment.
Ion implantation subjects tool components to some of the most destructive environments in the fab, combining high-energy ion beams, extreme voltages, and highly corrosive dopant chemistries. CrestTec delivers precision-engineered consumables and replacement spares designed to withstand these brutal conditions. Our solutions help you extend critical preventive maintenance (PM) intervals, maintain stable beam currents, and drastically reduce your cost of ownership compared to traditional OEM pricing.

Common support includes
- Graphite & Ceramics: High-purity machining for implant beamline consumables, insulators, and specialized thermal components
- Refractory Metals & Exotic Alloys: Precision CNC machining of Tungsten, Molybdenum, and Tantalum
- Seals and O-rings
- Parts Cleaning
- Complete refurbishment and repair of source assemblies to restore peak tool functionality
CrestTec can review drawings, photos, samples, dimensions, or application details to help determine the appropriate replacement or sourcing path for implant-related components.
Diffusion / Furnace
Diffusion and furnace applications require components that can perform reliably under elevated temperatures, controlled gas environments, and repeated thermal cycling. CrestTec supports replacement, sourcing, and refurbishment needs for components and assemblies used in semiconductor diffusion and thermal processing equipment.
Common support includes
- Valves, regulators, fittings, and flow control hardware
- Seals and O-rings specifically for extremely high-temperature environments
- Corrosion resistant coatings
- Quartz cleaning and repair
- Refurbishment of CKD VEC valves
CrestTec can help evaluate component requirements based on temperature, material compatibility, cleanliness, dimensional requirements, and application conditions.
