Spin Track 1 + 2 is an SVG 88 series track system from Rite Track. Both tracks have a HMDS priming module, a spin coater, and a hotplate. In fack, the only difference between the two tracks is the resist used in the spin coating. Spin Track 1 + 2 is capable of handling 150 mm wafers, as well as 100 mm wafets, but is currently set up for 100 mm wafer processing.
