	Outsource the Fab Work (they have open time/space to run "shuttles" - groups sponsor); They split the cost among a bunch of people. Can get ICs manufactured for $650-$1000. They get put in "shuttles" which people apply for and get decided upon by "lottery." See Skywater link.

=== Approaches ===

Discussion on varying approaches and implementations

==== Approach to project implementation ====

# Collaborative - work as a group on the same project (something new, something done before)
# Independent - everyone work independently on their projects

==== Approach to tech implementation ====

# Use an SEM
## Option 1 - get enough of the SEM fixed to operate manually
## Option 2 - get the full SEM working
## Option 3 - get the obviously broken part fabricated and replace it (part on back with dent in back of the SEM)
## Option 4 - do Project Awesome fundraising project
## Option 5 - the sputtering system issue needs to be resolved as part of the microfab process
## Option 6 - a cleaning chamber issue needs to be resolved as part of the microfab process
## Option 7 - working with hydrogen chloride indoors to etch glass issue needs to be resolved as part of the microfab process
## Option 8 - decide on wet etching vs. dry etching
## Option 9 - "rent" Ethan's personal-use SEM (assuming its working)
# Use The-Next-Best-Thing
## Option 1 - Sonic 8K - can -- stick PCB to layers of resin directly to fabricate things at 28 microns
## Option 2 - electro chemical plating
## Option 3 - UV lithography
## Option 4 - electron beam lithography
## Option 5 - "do what's been done before" (Ethan)
## Option 6 - "create a diode"...the simplest component we can start fabricating (Tristan)
## Option 7 - "create a DIY sputtering" system and publish results to community (Ethan)

===== More on Outsource approach: =====
tech is moving so fast that the Fab Shops of yesterday doing "1000 nanoML" are obsolete for commercial business/work doing "50 nanoML" and so then outsource to smaller clients that maybe "1000 nanoML" is all they need
