Deposition: Rich man’s brick laying
Starter's first deposition. Construction is something that everyone of you has witnessed time and time again. Most of these buildings are made of brick and concrete. Concrete acts as the adhesive, joining the bricks together. Deposition is the construction of semiconductor manufacturing. Basic understanding of it is constructing thin films by laying atoms on a substrate. Atoms are the bricks and the bond between the atoms is the concrete. Figure 1: Location of deposition in the process flow. This topic is an absolute mammoth to cover due to the number of techniques and materials that can be laid on top of one another in such a minuscule scale. The huge range and properties of materials, whether they be elements or compounds, calls for multiple processing procedures. One technique may work for one material and may completely fail for the other one just due to a difference in melting point. There are three basic deposition principles: physical deposition, chemical deposition, and...
