Due to its hard and brittle nature, silicon is currently finished by lapping and chemomechanical polishing (CMP). However, silicon can be plastically deformed in a ductile manner in ultraprecision machining at an extremely smooth surfaces. Using the ductile machining technology, the productivity of aspherical, diffractive optical components, and large-diameter substrates for recent microelectronic mechanical system (MEMS) applications can be significantly improved.
