The Toronto Microfluidics Foundry is a flexible environment for the fabrication and integration of polymer-based microfluidic devices and complements ECTI, the central cleanroom facility at the University of Toronto. Users need to be trained according to the UofT Health and Safety regulations as well as individually at the equipment and need to attend monthly user meetings. Fulfilling these requirements is a prerequisite for maintaining active user status.
Equipment Signup & Reservation
The purposes of signing up for equipment is: 1) to keep track of user hours for financial management of the facility 2) to make sure equipment is available when you need it. Please DO NOT FORGET to sign up for the equipment you will use (or have used).
The signup system will change shortly, but for now, please record your usage here:
Foundry Equipment Signup System
Note: to work after-hours, please email the Process Technology Committee (PTC-Foundry[at]mie[dot]utoronto[dot]ca)

Meetings
Please note that either attending the monthly meetings or informing us when you can't make it is mandatory for ALL users.
(a) no solvents, epoxy, PDMS debris allowed in laminar-flow hood
(b) always remove protective sheets at counter tops when dirty
(c) regularly organize pickup of solid waste
(d) order and restock supplies: - see emailed list
(e) don't turn off the right oven
(f) all new summer students need to (I) see Axel, (II) have Health & Safety training and (III) need to be trained in the foundry before getting access
(g) regularly clean up after yourself and others, report more persistent cleanliness issues
(h) update on new equipment and new facility
Supplies needed
Please record all supplies we are running low on. The foundry will order them, and when it is received, it'll be removed from this page.

Steps: 1 - Convert your file into a .gerber file. I use LinkCad.
2 - Send your file to padplot@primus.ca
3 - Call the company and tell him about it, make sure he knows where to ship it, etc.
4 - When you recieve the invoice & photomask, have Sheila Baker send a cheque out to him. The company only accepts cheques. You'll need Axel to sign the invoice with an account #.

RECIPE DUMP
Dump your numbered fabrication recipes here (note the date & your name).
A. TO FABRICATE STRAIGHT WALL ON THICK SU-8 SAMPLE
Problem: The features has a large overhanging edge near the top; the walls were slanted
Cause: the photomask was not pressed firmly against the photofilm which causes UV light to leak around the photomask apertures
Solution: before exposure, cover the photomask with a large piece of 3x2 inches glass. Then, apply two thick stacks (10-15) microscope slides on either sides of the cover glass to be used as weight.
Protocol:
Dehydration bake:
1. Dehydration bake @ 200 degrees for about 15 minutes
Spincoating:
1. 500RPM DWELL: 10s ACCELERATION: 10s
2. 2000RPM DWELL: 30s ACCELERATION: 5s
3. 0RPM DWELL: 0s ACCELERATION: 10s
Pre-exposure bake:
1. 7 minutes @ 65 degrees
2. 20 minutes @ 95 degrees
3. allowed to cool to room temperature
Exposure:
1. cover the photomask as described above
2. UV exposure for 20 seconds
Post-exposure bake:
1. 2 minutes @ 65 degrees
2. 7 minutes @ 95 degrees
3. 2 minutes @ 65 degrees
Develop:
1. Develop in 20ml of developer with mild to strong agitation for 20 minutes
2. Replace with 20ml of fresh developer
3. Develop further for another 20 minutes
An excel file with a fairly generic parameter table has been created on the desktop of the common computer in the fabrication lab. If you could input all your SU-8 fabrication data there, it'd be very useful. Thanks, Chris.
LAB SAFETY
Access to the foundry requires users to be complient with the UofT health and Safety regulations and to be individually trained by a member of Dr. Guenther's group at the equipment. Users that don't fulfill these requirements are denied access.
Waste will be picked up from the Foundry on every second Monday starting March 10, 2008.
