Rainbow series plasma etching machine  4420、4520、4720 Series Plasma Etcher
PRODUCT INTRODUCTION
Rainbow equipment is a traditional single chamber etching equipment of Lam, with the minimum etching line width of 0.5 μ m. Mainly used for etching silicon oxide, silicon nitride, polysilicon, silicon and metal materials of wafer with 8'' or under 8'' . Rainbow equipment covers a small area and has high equipment integration, which is suitable for large-scale production. The equipment is equipped with powerful RF system and gas system, which can accomplish the compatible development of various processes. Rainbow series equipment can be equipped with the options of electrostatic adsorption, envision system, etc., which can be chosen according to different process requirements. Rainbow equipment had very large market share, strong spare parts channels is AMTE’s strength.

APPLICATIONS
6'' and 8'' traditional silicon-based semiconductor production line.

APPLICATIONS AFTER UPGRADE
4'' and 6'' SiC, GaN, GaAs process line
