Westford USA, Feb. 08, 2023 (GLOBE NEWSWIRE) -- The single crystal silicon wafers market is witnessing positive growth, particularly in the Asia Pacific region, due to the increasing demand for ...

This efficiency was very close to the efficiency of dislocation-free single-crystal silicon (Czochralski (Cz) silicon) wafers for semiconductors (18.9%), which were evaluated concurrently.
