Structure for protecting a micromachine with a cavity in a UV tape

摘要

A protective layer includes a polymerized region, which forms a cavity in an interior surface of the protective layer. The protective layer is mounted to a micromachine chip such that an active area of the micromachine chip is located within the cavity of the protective layer. The protective layer protects the active area during front-side or back-side singulation of the micromachine chip from a micromachine substrate.
