SSE Spinner, Maximus 804, SSE Sister Semiconductor Equipment is a resist spinning system at Danchip which can be used for spinning on 2", 4" and 6" substrates.
The system is equipped with 2 different resists lines:
*AZ 5214E
*AZ 4562
and
*2 syringe lines, which can be used for spinning of e-beam resist.
'''The user manual, user APV, and contact information can be found in [http://labmanager.danchip.dtu.dk/function.php?module=Machine&view=view&mach=188 LabManager]'''
===Process information===
The typical flow for resist spinning is divided in 3 steps: video, spinning and soft bake.
You need to create a separate recipe for each station and then collect the recipes in a flow. For the video station we have 3 standard recipes for 3 different wafer sizes: 2inch, 4inch, 6inch. To create a recipe for the coater station you need to describe spinning sequence using the predefined functions. Then you create recipe for the hotplates. After all recipes are created they can be set together in the different flows. It is why we are not recommending the user just change some parameters in the recipe, this change can effect some other flows.
