Ultra-thin / ultra-thick / specially processed wafer
・ As sliced product (at the specified thickness)
・ Ultra-thin finish (150 μm)
・ Ultra-thin finish (150 μm)
We provide high-precision wafers capable of accurate groove fabrication for sensors and MEMS applications that perform deep digging by etching.
Smaller plane orientation (cutting angle) tolerance, smaller OF position angle tolerance, smaller thickness tolerance, more accurate flatness High quality such as single-sided mirror wafers from 2 inches to 12 inches, wafers with oxide film, etc. Wafers are provided. Square wafers, OF (orientation flat) notched (round) wafers to meet customer needs. Double-sided mirror, double-sided etch, double-sided wrap, etc. can be finished. Wafer thickness can be manufactured from 100 μm (4 inches) to 2,000 μm. CZ / FZ crystal small diameter type ~ 12inch
