Semiconductor equipment depends on vacuum-tight interfaces, particle-conscious surfaces, stable hole patterns and flatness controlled across substantial parts. We machine critical components for wafer processing, handling, gas delivery and test equipment, with material discipline, planned inspection and documentation aligned with your drawing and purchase order.
Behind every wafer fabrication tool is a supply chain of precision-machined hardware: chambers where deposition and etch processes occur, end effectors that move wafers, manifolds that deliver process gases and fixtures that keep assemblies aligned.
These components operate under high vacuum, plasma exposure, aggressive cleaning chemistry and cleanliness requirements where an uncontrolled burr, residue film or damaged sealing face can affect equipment performance. Geometry and surface condition therefore have to be planned as one manufacturing problem.
We support semiconductor equipment OEMs, subsystem builders and maintenance teams with prototype iterations, first-article builds, recurring production and drawing-controlled replacement parts. The machining route, finishing allowance, inspection method and required records are reviewed before release.
Customer-specific SEMI requirements, leak-test limits, particle criteria, cleaning instructions and packaging standards must be supplied with the RFQ so they can be included in the agreed manufacturing and verification scope.
Parts are manufactured to the released drawing, with vacuum interfaces, cleanliness-sensitive geometry, hole patterns, material identity and post-process requirements reviewed as connected characteristics.
Chamber bodies, liners, lids and pumping ports with controlled sealing faces, O-ring grooves, internal passages and surface requirements.
End effectors, alignment fixtures, robot interfaces and wafer-contact hardware designed around low mass, stiffness, cleanliness and dimensional stability.
Gas manifolds, distribution blocks, weldment bodies and fitting interfaces with controlled passages, sealing geometry and documented material identity.
Chuck bases, pedestal housings and thermal-interface plates whose flatness, parallelism and mounting relationships affect assembly performance.
Dense precision hole patterns with controlled position, diameter, edge condition and burr removal to support consistent flow distribution.
Mounting plates, brackets and equipment structures with repeatable datums and hole patterns for automated assembly and service access.
Probe fixtures, calibration references and inspection tooling for equipment development, incoming inspection and process verification.
Drawing-based or sample-assisted replacements for discontinued equipment components, with dimensions and acceptance requirements agreed before release.
A dimensional report is only one part of release. Semiconductor hardware also depends on burr condition, surface integrity, material behavior, contamination control and protection through downstream processing and shipment.
Final capability is confirmed against the released drawing. Part size, stock condition, wall geometry, datum structure, material behavior, finishing allowance and measurement access can materially change the manufacturing route.
Blind holes, intersecting passages and small edges are reviewed before programming so deburring and cleaning access are part of the machining route rather than a final correction.
Material condition, sealing geometry, surface finish, O-ring grooves and weld preparation are planned together for components used in vacuum service.
Stress-relieved stock, balanced roughing, controlled fixturing and in-process checks help manage distortion on chamber plates and handling structures.
Material grade, coating selection, masking and post-process verification are reviewed against the specified chemistry, temperature and plasma-facing conditions.
Tool access, drill strategy, true-position control and hole-by-hole burr risk are evaluated for showerheads, gas distribution plates and manifolds.
Cleaning method, inspection, drying, protection and packaging are defined from the receiving specification so a verified part remains protected through shipment.
Our semiconductor component manufacturing processes include CNC milling, CNC turning, mill-turn machining and Swiss machining. Engineering review selects the route around geometry, material, sealing interfaces and inspection requirements.
Use 3-axis and 5-axis milling for chambers, plates, manifolds and multi-face structures. Datum continuity, wall stability and tool access are planned for sealing grooves, precision hole patterns and intersecting passages.
Turn fittings, shafts, flanges and rotational hardware with drawing-defined sealing diameters, bores, grooves and threads. Workholding and inspection are planned around concentricity and vacuum-facing interfaces.
Combine turned profiles with live-tool milling for ports, flats and cross-holes on fittings, valve bodies and rotational components. Front and rear operations reduce transfers and help maintain feature relationships.
Machine small pins, slender shafts, miniature fittings and precision contact hardware from bar stock. Guide-bushing support and back-working operations support small diameters, fine threads and repeat production.
The manufacturing sequence covers drawing and technical requirements review, process planning, incoming material inspection, first article inspection, production machining, surface treatment and final inspection. Machining instructions and inspection records are tied to the approved drawing revision and production batch.
Provide the STEP model and dimensioned drawing with the current revision, material grade, quantity, surface finish, required delivery date and inspection requirements. Where required, an NDA is signed before drawings and models are exchanged.
Review geometry, dimensional and geometric tolerances, stock condition, tool access, workholding and measurement access. Identify features that affect machining feasibility, dimensional stability or inspection, and resolve proposed drawing changes with your engineering team.
Confirm the drawing revision, material specification, datum scheme, critical dimensions, surface finish and inspection requirements. Resolve drawing queries and document approved changes. Prepare the quotation from the confirmed part requirements, quantity and delivery schedule.
Define the operation sequence, machining datums, fixtures, cutting tools and cutting parameters. Prepare the NC program and inspection plan, review toolpaths through machine simulation, and establish the setup instructions for the first-article machining trial.
Specified material grades and stock forms are purchased exclusively from approved or qualified suppliers, matched to the requirements of your drawing and purchase order.
Check stock identification, dimensions, surface condition and material certificates against the specified grade, condition and purchase order. Record the heat or batch number and link the accepted material to the production work order.
Machine the first article using the planned NC program, fixtures and tools. Inspect drawing characteristics with the specified measurement methods, record the results and correct setup or program deviations before batch production begins.
Run the approved Semiconductor CNC machining program with the documented fixture setup, tooling and cutting parameters. Maintain the specified datums and machining sequence, and record approved changes to programs, tool offsets or setup instructions.
Measure critical dimensions and geometric characteristics at the intervals defined in the inspection plan. Monitor tool wear and dimensional trends, adjust offsets where appropriate, and recheck affected features after adjustment.
Check the completed machining operations against the drawing and review the in-process inspection results. Record dimensional conformity and segregate nonconforming parts before the batch proceeds to finishing or other subsequent operations.
Complete the specified deburring, grinding, polishing, surface treatment or heat treatment. Check treatment records and reinspect features affected by material removal, coating thickness or heat-treatment distortion.
Inspect finished parts against the drawing and final inspection plan, including dimensions, surface condition and finish requirements. Compile the required material certificates and inspection reports, verify quantity and identification, then pack parts to prevent damage during shipment.
Material selection affects vacuum behavior, corrosion resistance, thermal response, electrical performance, plasma exposure and dimensional stability. Grade, stock form and certification requirements are confirmed before procurement, with no substitution without written approval.
