Silicon Carbide Components for Semiconductor Equipment: Materials, Applications and Selection Guide

Silicon Carbide Components for Semiconductor Equipment: Materials, Applications and Selection Guide

2026-10-05

Silicon carbide components are the high-temperature, plasma-facing structural parts inside semiconductor process chambers. They include focus rings, edge rings, gas showerheads, chamber liners, wafer carriers, MOCVD susceptors, wafer boats and furnace tubes. Their value is not only high hardness. It is the combination of plasma resistance, thermal stability, electrical compatibility and dimensional control required to keep advanced processes repeatable.

Pin Chuck or Ring-Groove Chuck? Backside Particles in Lithography and Metrology

Pin Chuck or Ring-Groove Chuck? Backside Particles in Lithography and Metrology

2026-10-05

A particle trapped under the wafer is easy to overlook because the wafer surface may look clean. Yet the chuck contact pattern can decide whether that particle remains a local disturbance or becomes a focus, overlay or flatness error. This article compares pin chucks and ring-groove chucks for lithography and metrology and outlines what engineers should check before changing the process.
