Plasma Asher 5
Product name: PVA Tepla Gigabatch 380M
Year of purchase: 2024
The Plasma Asher 5 can be used for the following processes:
- Photoresist stripping
- Descumming
- Surface cleaning
- Removal of organic passivation layers and masks
Furthermore plasma processing using CF4 in plasma asher 5 can be used for:
- Etching of glass and ceramic
- Etching of SiO2, Si3N4, Si
- Removal of polyimide layers
Plasma asher 5 can be used for almost every material, but if you have any doubt if your materials are compatible/allowed in plasma asher 5, feel free to ask the lithography group at Nanolab.
