Fabrication process for an integrated circuit

The Microelectronics Fabrication Process Flow

A basic understanding of the fabrication technology for integrated circuit, which precedes that of MEMS in history, is necessary to understanding the micromachining process. A reader who is familiar with the basic microfabrication process of integrated circuits may skip this section. A fabrication process for integrated circuits generally involves many steps of material deposition, material
