Spin Coater: Gamma E-beam and UV

Spin Coater: Gamma E-beam and UV was installed at DTU Nanolab in June 2017. It is a Gamma 4M cluster from Süss MicroTec with spin coating, HMDS vapour priming, and baking modules. The system handles 2", 4", and 6" wafers without size conversion, using two separate coater stations.

The 2" coater station is equipped with 1 resist line, as well as 1 syringe line:

AR-P 6200.09 (CSAR)
Syringe, which can be used for various resists (anisole-based or PGMEA-based).

The 4"/6" coater station is equipped with 4 different resists lines:

AZ 5214E
AZ MiR 701
AR-P 6200.09 (CSAR)
AZ 4562

The processes that are available on the system are developed by Nanolab. Upon request, it is possible to establish new processes. Use of the syringe requires special training, and would as a starting point require batches in excess of 20 wafers.
