Basic Chemicals found in a Fab


There are basic chemistries found throughout a Semiconductor Fabrication Factory or what is commonly known as a Fab.  These chemistries are the work horses found throughout the Wafer Processing recipes of how to make a wafer.  The chemicals are Sulfuric Acid, Hydrogen Peroxide, Hydrochloric Acid, Hydrofluoric Acid, Ammonium Hydroxide, IPA, Ethyl Lactate, Phosphoric Acid, & Photoresist.  What I can tell you if you have a basic understanding of these chemicals and what their handling properties are, this knowledge will translate into a greater understanding of the properties of other chemicals.  So lets start with Sulfuric Acid.
