What is wafer equipment?
Wafer fabrication equipment uses mainly physical and chemical processes to create minute, multi-layer cir- cuits on round silicon wafers. While various types of equipment are used for performing these microscopic processes, most of these products can be grouped into several broad categories.
WHAT IS wafer technology?
A wafer is a piece of silicon (one of the most abundant semiconductors available worldwide) or other semiconductor material, designed in the form of a very thin disc. Wafers are used to create electronic integrated circuits (ICs) and silicon-based photovoltaic cells.
What equipment is needed for semiconductor manufacturing?
Examples of wafer fabrication equipment are oxidation systems, epitaxial reactors, diffusion systems, ion implantation equipment, physical vapor deposition systems, chemical vapor deposition systems, photolithography equipment, and etching equipment.
Is wafer a biscuit?
The term ‘wafer’ usually refers to a thin crisp type of biscuit (see Figs 30.1 and 30.2). In this chapter we shall be considering only wafers which are biscuits baked from batters between heavy hot metal plates. Ice cream wafers.
What is a wafer made of?
Wafers are formed from flour and water dispersions (batter) with small amounts of fat, sugar, salt and sodium bicarbonate, which are mixed and then confined in preheated moulds3. Yeast may be used in place or in addition to sodium bicarbonate.
