A method of fabricating the semiconductor wafer processing fixtures for having longer longevity on high stressed film applications such as LPCVD-SiN, silicon carbide and other ceramics than that of non-processed parts. One aspect of the invention includes nitriding, oxidizing, or carbiding a surface layer of a polysilicon part, such as furnaceware, for converting silicon to a silicon compound and its converted surface covers and masks the underlying polycrystalline structure. A plasma immersion ion implantation of a heavy noble gas or carbon, silicon or nitrogen is followed by to form high-energy states creating gettering states adjacent the surface and the ion implanted region serves to anchor production layers such as LPCVD-SiN forming on the polysilicon part. As a result of gettering effect, tightly bonded high stressed film onto a polysilicon part allows the CVD deposition of much thicker films without peeling or cracking as long as the gettering effect remains.
