ICPRIE (Alcatel AMS110)

ICPRIE (Alcatel AMS110)


A single-wafer load-locked DRIE system for deep etching of Si (Bosch) or glass substrates. Only photoresist or oxide may be used for etch masks (i.e., wafers cannot contain any exposed metal).


  • Si, SiOâ‚‚, quartz, and pyrex etch capability
  • Câ‚„F₈, SF₆, He, Ar, Oâ‚‚, CHâ‚„ chemistries
  • 3:1 resist:oxide selectivity for oxide etching
  • 25:1 resist:Si selectivity for Bosch etching
