In semiconductor device fabrication, the various processing steps fall into four general categories: deposition, removal, patterning, and modification of electrical properties. Deposition is any process that grows, coats, or otherwise transfers a material onto the wafer. Available technologies consist of physical vapor deposition (PVD), chemical vapor deposition (CVD), electrochemical deposition (ECD), molecular beam epitaxy (MBE) and more recently, atomic layer deposition (ALD) among others.

Precipitate delivery. Precipitate delivery refers to a delivery which results after an unusually rapid labor (combined 1st stage and second stage duration is <2hrs) and culminates in the rapid, spontaneous expulsion of the infant. Delivery often occurs without the benefit of asepsis.
