Wet Etching: Single Chip

Special holder for single chip etching.

Especially for customers who subscribe to multi-user manufacturing processes, AMMT’s single chip holders are a valuable tool. These miniaturized holders support single chip wet chemical etching with backside protection. Minimum edge exclusion widths are assured by custom-made sealing rings, which are available in a variety of shapes and dimensions.

Material compatibility, temperature range and AMMT’s low-stress locking mechanism are the same as for our successful series of Single and Tandem wafer holders. Please inquire for a tool for your specific chip dimension.
