Isotropic etching — In semiconductor technology isotropic etching is non directional removal of material from a substrate via a chemical process using an etchant substance. The etchant may be a corrosive liquid or a chemically active ionized gas, known as a… … Wikipedia
Deep reactive-ion etching — (DRIE) is a highly anisotropic etch process used to create deep penetration, steep sided holes and trenches in wafers, with aspect ratios of 20:1 or more. It was developed for microelectromechanical systems (MEMS), which require these features,… … Wikipedia
Nerve guidance conduit — A nerve guidance conduit (also referred to as an artificial nerve conduit or artificial nerve graft, as opposed to an autograft) is an artificial means of guiding axonal regrowth to facilitate nerve regeneration and is one of several clinical… … Wikipedia
