Abstract

A presentation of etch stop engineering is presented with a review of the present state of the art in etch stop micro‐machining. This review assumes a global definition for an etch stop and focuses on salient examples of common etch stop techniques, as well as unique and/or novel etch stop methods. A table of representative etch stops is also presented as a summary.
