The processing of semiconductors involves photolithography, a process for making metal lithographic printing plates by acid etching. The electronics based version of this is the processing of copper printed circuit boards. This is reviewed in the Figure below as an easy introduction to the photolithography involved in semiconductor processing.
The idea with a semiconductor device is that they can either block a voltage, or conduct a current with low power loss, ie an ideal switch. To block a voltage, there has to be a depletion region inside the device. It is perhaps easiest to see this in a pn junction like here. The figure shows the electric field as a function of distance.
IntroductionIn semiconductor manufacturing, wafers must undergo hundreds of processes before becoming final products. In a clean wafer fab, expensive environment control equipments can keep the relative humidity at a fixed level and wipe out particles in the air, to make sure products of high quality are produced via reliable manufacturing processes.
steps in a typical wafer manufacturing process. Crystal Growth and Wafer Slicing Process The first step in the wafer manufacturing process is the formation of a large, perfect silicon crystal. The crystal is grown from a 'seed crystal' that is a perfect crystal. The silicon is supplied in granular powder form, then melted in a crucible.

In this back end semiconductor manufacturing process the completed wafer is sliced into individual chips. Automated methods include mechanical sawing and laser cutting. Mechanical sawing is accomplished with a dicing saw that uses a circular dicing blade to cut the die into sizes ranging from 35mm to 0.1mm.
1 THE FABRICATION OF A SEMICONDUCTOR DEVICE The manufacturing phase of an integrated circuit can be divided into two steps. The first, wafer fabrication, is the extremely sophisticated and intricate process of manufacturing the silicon chip. The second, assembly, is the highly precise and automated process of pack-aging the die.
