The early 300 mm epi wafers have exhibited admirable epi thickness control down to 0.15 mm, superior suppression of COPs in the range of 0.09–0.16 mm and cometitive site flatness performance. However, current 300 mm epi wafers have a worse larger particle readings than polished wafers primarily due to epitaxial growth-related issues.
