Have you ever been reading through my textbook Fundamental Principles of Optical Lithography and thought “Boy, if I only had a set of Matlab exercises to do, I could really learn this stuff!”? Well if a laboratory manual full of Matlab problems is the only thing keeping you from learning optical lithography, your wait is over! Kevin Berwick of the Dublin Institute of Technology has been teaching a lithography course using my textbook and has been assigning Matlab problems to his class to help them get at the details of the topic. He has now collected up those problems and published a book called Optical Lithography Modelling with MATLAB®, Laboratory Manual to accompany Fundamental Principles of Optical Lithography, by Chris Mack. And if that is not enough to put any lithographer in a good mood, this book is available to be downloaded free! Click here for more information. A great Christmas present for that hard to shop for lithographer!
