#413 A word about substrates

Semiconductor process technology, understood as a technology developed and used for the purpose of manufacturing semiconductor devices, involves complex tools, methods, and procedures devised specifically for semiconductor device fabrication. Semiconductor manufacturing is unique as some devices, for instance cutting edge logic integrated circuits, are among very few mass-produced objects manufactured with truly atomic scale precision.


While discussing semiconductor manufacturing processes it is typically assumed that the substrate into which, or onto which devices are built is a rigid semiconductor wafer. What needs to be recognized, however, is that the way various processing step involved in the manufacture of semiconductor devices are implemented depends of the size, shape, degree of flexibility, and chemical makeup of materials used to construct such devices, and commonly referred to as “substrates”.

Posted by Jerzy Ruzyllo at 10:26 AM | Semiconductors | Link is a personal blog of Jerzy Ruzyllo. He is Distinguished Professor Emeritus in the Department of Electrical Engineering at Penn State University. With over forty years' experience in academic research and teaching in semiconductor engineering he has a unique perspective on the developments in this technical domain and enjoys blogging about it.

This book gives a complete account of semiconductor engineering covering semiconductor properties, semiconductor materials, semiconductor devices and their uses, process technology, fabrication processes, and semiconductor materials and process characterization.

With over 2000 terms defined and explained, Semiconductor Glossary is the most complete reference in the field of semiconductors on the market today.
