This 2 inch wafer dipper is designed to fit into a 250 ml Schott Duran beaker. Number of wafers that can be fitted are automatically calculated and taken into account. The user needs to think only the size of his or her beaker and ofcourse the wafer dimensions.
Motivation for this project is that outside industruial semiconductor production the processed wafer quantities are small. In academia it is common to process 1-3 wafers at a time. Therefore wet etching and other dipping is often done in a beaker. It is quite difficult to find small dippers for 2 inch wafers that fit into a standard 250 ml beaker.
