Attendees - Abhineet, Aryamman, Dhriti, Kartik, Shaashvat, Suchet

Decisions taken

• Controlling the spin coater motor directly with I2C commands rather than a driver.
  • @Suchet Gopal will do this
  • Mostly using a pico
  • Spin Coater should be capable of taking in an entire recipe and executing it.
  • Ellipsometry can be used to measure how good of a job we made.
• Whether we want to use vacuum for spin coater or not?
  • Multiple designs discussed
  • Final decision after meet with Waterloo guy - Do not use vacuum for proto 1.
  • Will probably use something like 2 way tape weakening it a bit.
• MVP for Litho
  • Exactly what the OSU guys did - project an image through a microscope onto a wafer.
  • Will borrow a microscope from Abhineet’s friend.

New Ideas

• Prof Veeresh- create a single box system, to spin coat, bake and do lithography.
  • This can be given to many colleges all over India.
  • Can be considered in the future- will be hard engineering wise - one step at a time.

Logistical Stuff

• Figure out what is the update on lab space.
• Running out of notion(switch to git?)
