After more than a decade of research and development, Tokyo Electron Miyagi Ltd. has introduced an innovative semiconductor etching method that achieves etch rates up to five times faster than ...

Deep reactive ion etching (DRIE) is a highly anisotropic plasma etching process that creates deep, near-vertical features in silicon and related microfabrication materials. DRIE extends ordinary ...

In this technique, fluorine-based plasma chemistry is used for silicon etching, which is combined with a fluorocarbon plasma process to offer sidewall passivation and enhanced selectivity to masking ...

After years in R&D, a technology called cryogenic etch is re-emerging as a possible option for production as the industry faces new challenges in memory and logic. Cryogenic etch removes materials in ...

One of the major steps in the chemical processing of subtractive printed boards is etching, or removal of copper, to achieve the desired circuit patterns. Etching is also used for surface preparation ...

Plasma etching is perhaps the most essential process in semiconductor manufacturing, and possibly the most complex of all fab operations next to photolithography. Nearly half of all fab steps rely on ...

There are five important characteristics to consider in selecting any dry etch process. These are rate, feature profiles, compositional selectivity, damage and uniformity across the wafer. In general, ...
