Cleanroom Transport, Wafer Carrier Pods, Machining Capabilities

With our multi-axis CNC machining centers and cleanroom assembly sites, we can guarantee quality. Our machining expertise allows us to deliver Wafer Carrier Pods faster across cleanroom transport. Each component, including wafer support structures, FOUP door assemblies, and contamination control latches for high-performance sealing, are precisely designed to optimize wafer protection and minimize contamination. The design ensures dependable performance for thousands of cycles transport. For sealing surfaces, we carry out CNC milling with ±0.010-mm flatness. We do high-precision drilling of kinematic coupling features with positional offsets of ±0.025 mm and thread milling of mechanical interface connectors. Resistance to particle shedding and compatibility with cleanrooms are our specialty. We leak test and validate particle contamination as well. Each component of the pods we manufacture incorporates polycarbonate, a clear, impact-resistant material as well as PEEK (polyetheretherketone), durable with chemical resistance and mechanical strength. We also use anodized-coated aluminum 6061-T6 for added structural support, and other specialty materials such as 10⁶ to 10⁹ Ω/sq conductive polycarbonate for ESD protection, and durable stainless steel 304/316 for structural reinforcement. We also use antistatic polymers compliant with SEMI S8. To meet high standards for contamination control, we generate fewer than 0.1 particles (diameter > 0.1µm) per liter of air. We meet high standards for sealing integrity with leak rates below 1x 10-³ scc/s at a 0.5 psi differential pressure of air, and highly durable mechanical structures that withstand more than 100,000 door opening cycles. Operating conditions are continuous within the 15 °C to 35 °C temperature range.

FAQs: Plasma Etching Chamber Parts for Semiconductor Tools Applications

Chamber parts of plasma etching should contain precision and custom machining of the chamber liner components with dimensional tolerances of ±0.050 mm, electrodes of the chamber having flatness of ±0.025 mm to induce uniform plasma, gas distribution shower heads of 50 to 500 holes to guarantee ±3 percent uniformity of flow and plasma, RF coupling rings for matching value of impedance and micro to nano in range of ±5 percent, and various process kit components (focus rings, edge rings) with matching of thermal expansion to silicon wafers. There are some of these components in the kit that require vacuum sealing of the set, with leak rates below 1×10⁻⁹ torr·L/s, thermal erosion stability with degradation rates on the range of 1 µm of erosion in 1000 working hours, stability with regional thermal cycling of 25°C to 400°C, and generation of particles below 0.01 greater than 0.1 micron particles in series per cm² for exhausting cycles of plasma processing greater than 10,000 cycles will be required, and these parts will also require sit.

Anodized aluminum 6061-T6 has a low density of 2.7 g/cm³, is easy to work with and can achieve a surface finish of 1.6 Ra microns and lower, has a 25 to 50 µm thick anodized plasma resistant coating, and has a thermal conductivity of 167 W/m·K which allows for sufficient heat dissipation. 316L stainless steel has the best vacuum compatibility of the materials with an outgassing rate of less than 1×10⁻⁸ torr·L/s·cm², is cleanroom compatible, has corrosion resistant plasma chemistries, and has a thermal expansion of 16 µm/m·°C. Ceramics, specifically Al2O3 and Y2O3, have the best resistance to plasma erosion with wear rates on the order of 10 to 50 times less than that of metals, can withstand temperatures up to 1500°C, have good dielectric strength which allows for RF isolation, and are inert to fluorine and chlorine containing plasma chemistries.

Through 5 axis CNC milling, gas chambers with complex geometrical shapes are achieved with a tolerance of ± 0.025 mm. Also, gas distribution holes are drilled precisely with a diameter deviation of ± 0.025 mm and a positional deviation of ± 0.050 mm. High speed rotary cnc machining provides with chamber parts with a diameter of 1.6 Ra microns. Vacuum sealing threads with 2B class tolerance are produced by thread milling. Wire EDM processes are able to cut in a tolerance of ± 0.01 mm to make intricate designs in cooling channels of electrodes and is the finish technology. EDM is best to make pieces with a diameter of 300 mm. Depth of O-ring grooves is achieved with a deviation of ± 0.050 mm and the surface finish also is 0.8 Ra microns which is best for good sealing of chambers.

The tolerances we maintain for chambers are: flatness at ±0.025 mm for even plasma gaps, gas hole diameters at ±0.025 mm for flow uniformity within ±3% for O-ring grooves with depth tolerances of ±0.050 mm, for leak rates >1×10⁻⁹ torr·L/s, electrode parallelism at ±0.050 mm for reliable RF coupling, mounting hole position at ±0.075 mm, a surface finish of 0.8 to 3.2 Ra microns for plasma resistance, and overall ±0.100 mm. These tolerances support plasma uniformity with etch rates that have a deviation of less than ±5% for the entire wafer, vacuum integrity with base pressures of less than 1×10⁻⁷ torr, thermal cycling stability from room to 400°C, and a life expectancy of 10,000 RF hours.

Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.
