What it is
How it works
Where it fits in the process flow
The MJB-3 is used after photoresist is applied to the substrate. The MJB-3 supports standard photoresist processing in a teaching cleanroom workflow.[2][3]
Applications
The MJB-3 is used with a variety of positive and negative photoresists. The MJB-3 supports lithographic pattern transfer for small substrates and sample pieces.[1][2]
- Mask alignment
- Photolithography
