Agenda & Priority List

Back to Process Hybrid Silicon.

Priority list

  • Process development:
    • Etch-back module (Jock, Jared)
    • Need to converge on process follower (Excel?)
  • III/V epi design
    • Finalize design
    • Order epi
  • III/V SOA design
  • III/V SOA mask design (UCSB-E-Phi-dev-2 @ UCSB E-Phi Runs)
    • Issue: Epi will arrive > 3 months -> test process follower with OPSIS run?


Issues brought up in meetings

  • Jon P.: Resist difficult to remove after Si-doping implants
    - can remove with long strip, pirhana (hot)
    - long-term:  move to thin SiO2 underlayer (implant through this) and remove with BHF
  • Jared H.: edge bead (may not be an issue, esp. for 4" wafer processing - use stayout of 5-10mm)
    - for small samples, can surround with additional chips during spin

  • Jon P.: Resist nonuniformity for multiple-die exposure -> >= 1-cm stay-out area?
  • Jock: Grating module works for etch depths < 120 nm
  • Bandgap issue: PL peak is not equal to lasing wavelength, and lasing wavelength is not equal to SOA gain maximum
    • First have nice gain spectrum before we discuss further
