| Etching FOx-22 in PT-MTL | 07/25/2014 (all day) | Request to etch FOx-22 spin on glass in PT-MTL etcher. | Plasma Therm Versaline LL ICP Metal Etcher (PT-MTL) | Approved. PT-Ox recommended due to CHF3 availability but material is approved for PT-MTL. |
| Etching Cytop 809M in PT-Ox | 07/25/2014 (all day) | Request to etch Cytop spin on glass in PT-Ox etcher. | Plasma Therm Versaline LL ICP Dielectric Etcher (PT-Ox) | Approved. |
| Use of Crystal Bond 509-HMP in Lampoly | 07/15/2014 (all day) | Request to use Crystal Bond 509 to mount chips on wafer in Lampoly etcher. | Lam Research TCP 9400 Poly Etcher (lampoly) | Conditional approval. Crystal Bond use requires additional characterization and procedure definition. Alternatives proposed. |
| Use of Crystalbond 555 in Lampoly | 07/15/2014 (all day) | Request to use Crystal Bond 555 to mount chips on wafer in Lampoly etcher. | Lam Research TCP 9400 Poly Etcher (lampoly) | Conditional approval. Crystal Bond use requires additional characterization and procedure definition. Alternatives proposed. |
| GaAs processing and citric acid introduction | 06/25/2014 (all day) | Request to use GaAs substrates in gold contamination level tools and to bring in citric acid. | Wet Bench Flexcorr 1 (wbflexcorr-1) | Approved. |
| Use of Copper Mask in SF6/O2 chemistry in PT-MTL | 06/10/2014 (all day) | Request to use copper as a masking layer for etch in PT-MTL using SF6/O2 chemistry. | Plasma Therm Versaline LL ICP Metal Etcher (PT-MTL) | Rejected. Risks to both equipment and subsequent users deemed too high. Efforts to find alternative path ongoing. |
