Thanks for forwarding the replay. Brad Mattson said (I think it was his voice) claimed that their hot plate RTP approach is compelling compared to AMAT and Steag (sp?). However, no detailed explanations were given. I am no heat transfer expert but it seems to me the physics are the same, that both lamp and hot plate approaches use radiant heating. Has MTSN published test data that show faster heating and higher uniformity? I remember the AG RTP specs. being being fast and uniform, and AMAT still wiped them out. CVD and strip business sound good.
