Overview

Komatsu NTC is a Komatsu group company headquartered in Nanto, Toyama. For wafer manufacturing it supplies multi-wire saws that slice many wafers from an ingot at once.

Its lineup includes saws for silicon ingots and for SiC and other compound materials, where diamond wire is used to cut hard, brittle crystals.

Business: Wire saws for slicing silicon and SiC ingots

Why it matters

  • The material lost to the saw kerf is a direct yield loss, which matters most for expensive SiC crystals.
  • SiC is much harder than silicon, so slicing is one of the slow and costly steps in SiC wafer production.
