Abstract

A wafer processing system occupies minimal floor space by using vertically mounted modules such as reactors, load locks, and cooling stations. Further saving in floor space is achieved by using a loading station which employs rotational motion to move a wafer carrier into a load lock. The wafer processing system includes a robot having extension, rotational, and vertical motion for accessing vertically mounted modules. The robot is internally cooled and has a heat resistant end-effector, making the robot compatible with high temperature semiconductor processing.
