This topic is aimed at giving the students an Idea about how a particular component is fabricated on a  semiconductor wafer using the different processes that they learned in previous topics. In this topic, a simple example of the fabrication of a transistor chip is explained in a very simple and understandable way.

This topic is aimed at giving students an idea of how a wafer chip is converted to a chip after its assembly process. The assembly process of a wafer can be seen as the process where the connections to the chip are made available for more practical use of the chip in the real world. Here, the complete assembly process is explained using the example of the acceleration sensor module. The focus is more on the process part rather than the design of the process part.
