Unaxis 770 Deep Si Etcher

CAC Name: UN 770

Bosch Etcher for deep silicon etching

Manager: Meredith Metzler

Backup: Vince Genova

Equipment Training
Training is conducted on an as needed basis with groups of 4 or 5 people. Please contact M. Metzler via email to schedule a session. The training sessions will usually be on Wednesday mornings.

Description:

A single chamber (licensed Bosch fluorine process) inductively coupled plasma / reactive ion etcher, the Unaxis SLR 770 etcher is used to etch deep patterns in single crystal silicon substrates. The resulting features are used for MEMS and biological applications. Etch rates of up to 2 microns per minute and aspect ratios of 20:1 can be obtained using photoresist or silicon dioxide as a masking medium.

Capabilities:
