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.
precipitously adv 1: very suddenly and to a great degree; conditions that precipitously increase the birthrate; prices rose sharply [syn: precipitously, sharply] 2: abruptly; in a precipitous manner; the mountains rose precipitously from the shore
By Anne Marie Helmenstine, Ph.D. Precipitate Definition: to form an insoluble compound either by reacting two salts or by changing the temperature to affect the solubility of the compound. Also the name given to the solid that is formed as a result of a precipitation reaction.Example: Mixing silver nitrate and sodium chloride in water will cause silver chloride to precipitate out of solution as a solid.Return to the Chemistry Glossary Index.lso the name given to the solid that is formed as a result of a precipitation reaction.
