Patent ID: 8796589

Claim:
A substrate processing system comprising: a chamber having a plurality of openings through which a substrate is transported; a substrate carrier opener coupled to a first one of the plurality of openings; a thermal processing chamber coupled to a second one of the plurality of openings; and a wafer handler within the chamber, comprising a first arm having a substrate clamping blade including a clamping mechanism configured to transport only non-high temperature substrates and a second arm having a non-clamping blade having no clamping mechanism and configured to transport only high temperature substrates, wherein the clamping blade and non-clamping blade are adapted to be used concurrently, wherein the first arm having the substrate clamping blade transports wafers at a first speed and the second arm having the non-clamping blade transports wafers at a second speed, and the first speed is greater than the second speed.
