Deep reactive-ion etching (DRIE) is a special subclass of reactive-ion etching (RIE). It enables highly anisotropic etch process used to create deep penetration, steep-sided holes and …

Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module in fabrication, and every wafer …

Wafer and die level uniformity effects in Deep Reactive Ion Etching (DRIE) are quantitatively modeled and characterized. A two-level etching model has been developed to predict non …

A typical die delayering sequence starts with either plasma or reactive ion etching to remove the nitride passivation on top of the die surface, followed by a series of wet chemical etching steps …

Apr 11, 2023 · Reactive Ion Etching (RIE) is a dry etching technique widely used in semiconductor manufacturing, MEMS fabrication, microfabrication and nanotechnology to create patterns on …

Secco - (or Dow etch) The Secco etch can be used to delineate dislocations in <100> and <111> silicon as well as swirl defects, etch pits, stacking faults, and oxygen clusters. However, this …

Plasma dicing offers considerable benefits to users, including narrower kerf widths that allow >80% more die per wafer (depending on die size). Cleaner processing improves yields in die …

Our DSi-v module offers higher etch rates and low non-uniformity for non-critical or high load cavity etching, and blanket silicon etching for via reveal or thinning.

Deep Reactive Ion etching of Silicon (DRIE), or Deep Silicon Etching (DSiE), is a highly anisotropic etch process used to create deep, steep-sided holes and trenches in …

May 30, 2017 · Plasma Dicing uses Deep Reactive Ion Etch (DRIE), also known as The Bosch Process. This is a well-established "front-end" technology, used in silicon MEMS …
