==Supported processes==
This tool is primarily used to expose photodefinable materials. The lamp output is calibrated to the 405 nm peak at 20 mJ/sec with <!-- We recommend creating a subpage detailing the supported processes for 5% uniformity across the tool, which will be generated if you leave the link below4” area. Alternatively, you may include the information on The 365 peak output is about half of this pageand tracks very well however is not routinely calibrated. In that case We allow 4” masks, the Supported Processes document from the equipment manual can be included here5” masks, 7” masks, transparencies, shadow masking, using {{#widget:GoogleDoc|key=googledocid}} -->or a manually timed flood exposure.
This tool is primarily used to expose photodefinable materials. The lamp output is calibrated to the 405 nm peak at 20 mJ/sec with 3% uniformity across the 4” area. The 365 peak output is about half of this and tracks very well however is not routinely calibrated. We allow 4” masks, 5” masks, 7” masks, transparencies, shadow masking, or just flood exposure. The tooling can also be changed out to provide wafer to wafer alignment for wafers that need to be aligned before bonding in the SB6-E.  Exposure of all LNF approved photoresists are allowed on this tool in accordance with standard operating procedure. More , for data on exposure times can be found on datasheet for the specific resist please see that resists wiki page, such as [[photoresistSPR 955]].

==Checkout procedure==
<!-- Describe the checkout procedure for the tool. For example: -->
# Read through the [ Standard Operating Procedure].
# Complete the [ SOP quiz]
# Create a [ Helpdesk Ticket] requesting training.
# A tool engineer will schedule a time for initial training.
# Practice with your mentor or another authorized user until you are comfortable with tool operation.
# Schedule a checkout session with a tool engineer via the helpdesk ticket system. If this checkout is successful, the engineer will authorize you on the tool.
==Maintenance== # Complete a [[Lithography training session]].
