Electron-beam lithography: resists

This page contains data for the different EBL resists available at MIT.nano, typically the manufacturer's datasheet and safety data sheet, as well as spin curves obtained with spinner-EBL. Note that these spin curves will be more exact, since they have been measured on our spinner.

The spin curves include an interpolation function that can be used to calculate the spin speed necessary for a particular thickness.

Papers

Spin curves

Conditions: 

  • Small samples
  • Spread at 750 rpm for 5 s, accelerate at 10 krpm/s to final speed, 60 s at final speed
  • Bake on hotplate at 180 deg. C for 120 s.

Note: PMMA-950K-A8 at 6krpm produced very poor results.
