The GCA AS200 Auto Step is a submicron capable projection lithography 5X reduction exposure system. The system can automatically perform all wafer processing and handling operations of 4" wafers and can be used to align and expose pieces. It is primarily used to expose an array of images directly onto the surface of a wafer.
LNF is now under contract with SCS, Inc. They will be servicing and optimizing our system over the course of the next year or so. They've stated they can achieve 0.5 um resolution across field with local alignment accuracy better than 0.25 um once repairs and optimization are completed. We'll keep users posted. Their first service visit is scheduled for the week of 9/14/15. The tool will be offline for the first half of the week. Please plan accordingly.
- 0.75 um resoution across field(current-see announcement) 0.5 um overlay accuracy (current)
- 10 mm pieces up to 6" wafers
- Substrate thicknesses (with existing chucks) 175-675 um (the range from 400-475 um thick may not work)
- High resolution/high precision mask making possible if there's interest
- RF / Power Specs
- Wafer Size
- Wafer type
- Any mounting?
- Wafer thickness
The GCA AS200 AutoStep is designated as a Semi-Clean class tool. Below is a list of approved materials for the tool. Approved means the material is allowed in the tool under normal circumstances. If a material is not listed, please create a helpdesk ticket or email firstname.lastname@example.org for any material requests or questions.
There are several processes for this tool supported by the LNF, which are described in more detail on the Processes page.
In addition to these, this tool has a number of user-created recipes for etching a wide variety of materials. Some of these recipes are documented on GCA AS200 AutoStep user processes. If you are curious if your material can be processed in this tool, please contact the tool engineers via the helpdesk ticket system.
