FAQs: Carrier Plates for Wafer Transport Applications
Carrier plates are protective and processing handling devices for semiconductor wafer. Designed for extreme precision, they serve as support structures for substrates. There are several types. There are process carrier plates used for CVD, etching, and ion implantation at 1200°C, vacuum chuck carriers for polishing and grinding, and edge-contact carriers for wafer backside contamination. There are batch processing boats for multiple vertical wafer processing in tube furnaces, cassette plates for automatic wafer storage and transfer, electrostatic chuck carriers for plasma processing, and thermal management plates with integrated heating or cooling. Finally, 200mm and 300mm transport trays for FOUP and wafer carrier systems support compound semiconductors and MEMS substrates between fabrication sequences.
Carrier plates are crafted using precision CNC milling which involves creating profiles with wafer pockets, edge support features, and vacuum channel networks, all while keeping tolerances to within ±0.001 inches. The upper surface is flat with a precision of 10 to 25 microns, and a surface finish of less than 1.6 Ra microns is attained through surface grinding. Pockets are machined to create recessed wafer nests with depth control of ±0.002 inches. Vacuum, lift pin, and temperature sensor cavity drilling is performed with hole position accuracy of ±0.005 inches. Vacuum lifting and pin holes are aligned with precision to control the wafer. EDM machining of graphite and ceramic materials makes intricate cooling channels, while lapping achieves ultra-flat support surfaces critical applications which have a flatness of 5 microns.
Aluminum 6061-76 and 5083 have a thermal conductivity of 167 W/m-K, a relatively low cost, and enough power for non-high-temperature applications. They are also appropriate for class 10 and 100 cleanroom environments after surface finishing. Machining is also easily performed for complex precision pocketing. Graphite of any classification, including isomolded and EDM, is low expansion, high temperature capable to 3000°C in inert atmospheres, and chemically inert to process gasses. Graphite has silicon-like expansion, is self lubricating and has low expansion, which is beneficial to graphite composites. Of any material, silicon carbide carriers provide maximum thermal conductivity of 270 W/m-K, and high temperature stability of 1600°C. Silicone carbide substrates are ideal when thermal expansion is a problem. Al oxide and Al nitride ceramics provide electrical insulation and thermal conductivity of 20 - 170 W/m-K and ultra high purity for ceramic to keep it free from metallic contamination make it ideal for high-end components.
25 microns, control on wafer positioning is achieved with pocket depth tolerances of ±0.002 inches, overall plate flatness of 25 microns was achieved for a 300mm diameter plate, accuracy of ±0.005 inches for positioning vacuum holes and lift pins, and the overall finish of support surfaces in the system was kept below 1.6 Ra microns to ensure minimal particle generation. For 200mm, 300mm, and rectangular semiconductor carrier plates, thicknesses with tolerances of ±0.010 inches were maintained, and thermal uniformity of ±2°C was achieved during processing.
Yes, we do rapid prototyping specifically for thermal testing and process validation within production tool environments, low-volume production for specialized semiconductor processes and R&D applications producing 20 to 200 carrier plates, and high-volume production for fab consumables supplying semiconductor manufacturers globally with thousands to tens of thousands of plates annually including full dimensional inspection using CMM and laser interferometry, flatness measurement across entire surface, thermal cycling validation from room temperature to process temperature, particle generation testing per SEMI standards, material purity certificates, and complete documentation packages.
All components are manufactured under ISO 9001 certified quality management systems with material traceability including purity analysis and trace metal content documentation, dimensional verification using precision measurement equipment, flatness documentation with full-surface mapping, thermal performance validation, and adherence to semiconductor industry requirements including SEMI standards for materials and cleanliness, outgassing specifications per SEMI F19 for vacuum compatibility, particle generation limits per SEMI E37, chemical resistance to process chemistries, and thermal specifications ensuring process temperature uniformity and dimensional stability.
The various options are hard anodizing Type III on aluminum with coating thickness from 25 to 100 microns with surface hardness of more than 65 HRC giving excellent wear resistance, surface electropolishing on aluminum with Ra below 0.4 microns for surface defect removal and reduced particle adhesion, plasma spray coating for chemical resistance and thermal barrier with yttria or alumina, CVD (chemical vapor deposition) coating with SiC and pyrolytic graphite, for high purity surfaces, precision grinding with controlled Ra of 0.8 to 3.2 microns and additional treatments which include passivation, grinding and release with PTFE coating, for low friction, ceramic for electrical insulation and to complete the array, surface texture improvement with Ra selected for specific polishing operations.
For prototype carrier plates for process testing, 10-14 days can be met depending on the material and coating required, otherwise standard lead times for completed designs are 15-20 business days with the full work cycle of machining, surface treatment, cleaning, flatness checks, and the complete series of steps to verify cleaning. The other category tends to be more complex custom carriers with integrated heating elements or specialized coatings which need between 4 and 7 weeks to complete.
Certainly. We tailor carrier plates for specific processing temperatures, whether for low-temperature applications under 200°C, high-temperature furnace processing up to 1200°C using graphite or SiC, for ultra-high temperatures up to 1600°C with specialized ceramics, or for varying wafer sizes and shapes such as 200mm, 300mm, rectangular, and irregular substrates. We provide vacuum-compatible carrier plates that meet outgassing requirements for plasma processing and edge-contact configurations that minimize backside contamination. We integrate thermal control features with embedded heaters or cooling channels, and offer extra custom features like electrostatic clamping surfaces, multi-level stacking for space efficient vertical transportation, automated handling interfaces for FOUP, and AMHS compatibility.
Pocket flatness of 10–25 microns will uniformly support a wafer to avoid bowing and warping. This minimizes and removes distortions in the patterns and patterns overlay errors in lithography, which results in improved bowing and warping. Controlled pocket depth of ± 0.002 inches will avoid inconsistencies in the positioning of the wafer through repeatable thermal contacts. This also ensures a temperature distribution of ± 2°C over the wafer diameter during the CVD and diffusion, and a uniform wafer temperature of 0.002 inches pocket depth during the CVD diffusion processes. Hole positioning accuracy of ± 0.005 inches ensures the vacuum is properly distributed which helps in wafer retention, helps automated lift pin actions, and minimizes the chance of losing the wafer in the vacuum. Surface finishes smoother than 1.6 Ra microns will produce lesser particles and minimize the Class 10 cleanroom compatible with <0.1 particles per wafer touch. Channel patterns improve temperature uniformity through the process, reducing the edge to center temperature difference by 30–50%. This is made with uncompromising materials which help with dimensionality on the thermal charged HF, HCl, and plasma chemistries through more than 500 process cycles. Matching thermal expansivity minimizes and reduces differential stress on the temperature ramp.
Precision manufacturing allows dependable wafer movement for front-end wafer processing, ion implantation, CVD and PVD depositions, thermal annealings, and epitaxial growth. This requires handling without contamination, thermal uniformity within ±1°C for critical processes, and multi-year dimensional stability, all while maintaining automated material handling system compatibility in high-volume semiconductor fabrication facilities.
