Abstract
Methods, systems and apparatuses for high throughput substrate transfer are provided. According to various embodiments, the methods and systems described use robots having dedicated end effectors for hot and cold wafers or other substrates). Throughput is increased by optimizing the transfer of both the hot and the cold wafers. Also described are wafer transfer apparatuses having end effectors configured for supporting either hot or cold wafers. In certain embodiments, dual arm robots having dedicated hot and cold wafer arms are provided. Also provided are methods of transferring substrates that to improve overall throughput. The methods involve transferring hot and cold substrates at different accelerations.
