Title: Part for semiconductor producing apparatus and method of producing the same
Inventor: MAJIMA KAZUTAKA
IPC: H01L21/302
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent the contamination of a semiconductor wafer by setting thickness of a process brittle layer to a specific value or less, the layer being on at least a surface exposed to a plasma of high-purity silicon carbide sintering part used in a semiconductor producing apparatus using plasma, thereby reducing the amount of particles. SOLUTION: In a plasma etching apparatus 1 as semiconductor producing apparatus, the thickness of a process brittle layer 12 on a grinding surface layer of a dummy ring 8 formed of a high-purity silicon carbide sinter located in the periphery of the upper surface of a lower electrode plate 5 is set to 1 μm or less, preferably 0.5 μm or less. In this way, by drastically reducing the thickness of the process brittle layer 12 to about 1 μm, an amount of particles caused by lifting off the process brittle layer is surely reduced, even if the dummy ring is exposed to plasma. Thus, this can prevent a semiconductor wafer supported by the dummy ring 8 from being contaminated.
