Masks for applying dots on semiconductor wafers

摘要

A mask and an assembly utilizable in the production of a multiplicity of capacitors on selected regions of a semiconductor wafer includes a shaped, thin sheet of material having spaced-apart holes made therein and at least one recess formed adjacent each of at least two opposite edges thereof, the recess being configured to be engaged by a substantially matching portion of a clamp releasably affixing the mask onto the wafer.
