It is about 98% pure. MG-Si is not pure enough for direct use in electronics manufacturing. A small fraction (5% – 10%) of the worldwide production of MG-Si gets further purified for use in electronics manufacturing. The purification of MG-Si to semiconductor (electronic) grade silicon is a multi-step process, shown schematically in Figure 2.

process. This is done to eliminate unsatisfactory wafer materials from the process stream and to sort the wafers into batches of uniform thickness and at a final inspection stage. These wafers will become the basic raw material for new integrated circuits. The following is a summary of the steps in a typical wafer manufacturing process.

Semiconductor manufacturing processes. Semiconductor devices are built up in a series of nanofabrication processes performed on the surface of substrates made from highly pure single crystal silicon. These substrates are usually known as wafers. Commonly used wafers include the 300 mm type, which offers the advanced miniaturization required for ...

Semiconductor Manufacturing Technology 2/41 by Michael Quirk and JulianSerda Objectives After studying the material in this chapter, you will be able to: 1. Draw a diagram showing how a typical wafer flows in a sub-micron CMOS IC fab. 2. Give an overview of the six major process areas and the sort/test area in the wafer fab. 3.

The stock removal process removes a very thin layer of silicon and is necessary to produce a wafer surface that is damage-free. On the other hand, the final polish does not remove any material. During the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish.

Similarly, the etching process in semiconductor fabrication uses a liquid or gas etchant to selectively remove unnecessary parts until the desired circuit patterns are left on the wafer surface. By repeating this process on multiple layers, …

Die preparation is a part of the wafer manufacturing process. It involves two major steps: wafer mounting and wafer sawing. Wafer mounting is the process of mounting a wafer on a plastic tape that is connected to a ring. This step aims to provide support to assist the processing of the wafer from wafer sawing to die to attach.
