This circular fused quartz substrate features six precisely machined bottom surface bosses, engineered for semiconductor and optical thin-film processing. With a compact 15mm diameter and double-sided fine grinding, the integral boss structure lifts the substrate off the carrier surface, eliminating contact-area contamination and ensuring uniform coating performance.

Chip and wafer coating carrier substrate. The six bottom bosses suspend the substrate above the carrier plate, ensuring uniform film deposition without adhesion to the base plate—improving process yield and repeatability.
Vacuum coating fixture pad for optical components. The boss structure prevents bottom surface scratching and residual liquid accumulation, maintaining optical surface quality during multi-layer coating processes.
Powder specimen support platform for high-temperature sintering. The ventilated gap created by the bosses promotes even heat distribution across the sample, preventing localized overheating.
Precision bonding and positioning substrate for optoelectronic components. The boss protrusions serve as adhesive-limiting boundaries, controlling bond line thickness for consistent assembly quality.
Compared to conventional flat substrates, the six-boss elevated structure prevents full-surface contact with the carrier plate. This eliminates coating blind spots, reduces workpiece adhesion and sticking, and significantly improves production yield. Combined with fused quartz's superior resistance to process chemicals and high temperatures, this substrate delivers reliable performance for demanding semiconductor and optical manufacturing environments.
