1. Wafer Preparation Before the long process of creating an integrated circuit can begin, a wafer of semiconductor material must first be manufactured. This essential substrate is the ultimate foundation upon which all integrated circuits are created. Basic Steps of Silicon Wafer Manufacturing and Preparation steps outlined below. 9 Crystal Growth and Wafer Slicing Process 9 9 9 9

3. What is Fabrication Semiconductor device fabrication is the process used to create chips. It is a multiple-step sequence of photographic and chemical processing steps during which electronic circuits are gradually created on a wafer made of pure semiconducting material. Silicon is the most commonly used semiconductor material today, along with various compound semiconductors. 9 Mask 1 defines the areas in which the deep p-well diffusions are to take place on an n-type substrate . 9 Mask 2 defines the thinox (or diffusion) regions, namely, those areas where the thick oxide is to be stripped and thin oxide grown to accommodate p and n-transistors and wires 9 Mask 3 is used to pattern the polysilicon layer that is deposited after the thin oxide 9 Mask 4 is a p-plus mask used to define all areas where p diffusion is to take place.

(cont…) 9 Mask 5 is usually performed using the negative form of the p-plus mask and defines those areas where ntype diffusion is to take place. 9 Mask 6 defines contact cuts . 9 Mask 7 defines the metal layer pattern 9 Mask 8 is an overall passivation layer that is required to define the openings for access to bonding pads .
