This is a welcome 2nd edition of Sze's basic introduction to the technology underlying modern conventional semiconductor devices. The first edition of 1985 served the needs of its time admirably, but the 17 years since have seen much progress in the field, especially in the area of fabrication technology.
It should be stressed that this text is an introductory text, covering the basics well, but not taking the material much beyond the intermediate level. It is also very much an engineering text rather than a physics text, for the focus is squarely placed on the technology and not the underlying solid-state physics. As such, it is suited to undergraduate electrical/electronic engineers wishing to gain some appreciation of the physics underpinning conventional semiconductor devices, and the way they are fabricated, or for physicists wishing to gain some perspective on the fabrication and operation of the same, but it is in no way a comprehensive textbook on semiconductor physics.
Nevertheless, the material that is presented is well chosen, and well explained. The English prose style is somewhat pedestrian, but this is no great flaw in an engineering textbook. All the essentials of semiconductor materials (almost exclusively Si and GaAs) are described, the p-n junction, as well as the major device types (BJTs, (MOS/MES)FETs, microwave diodes, LEDs, lasers, etc.) and the modern technologies employed for their fabrication. In some senses, the section on fabrication technologies, taking up fully a third of the book, is perhaps its best section, for fabrication is rarely given such emphasis (although, again, not detailed, but covering most salient points) in an introductory book.
The pedagogical method employed by Sze is sound, and relevant worked examples are provided. The only short-coming is perhaps the relative brevity of the end-of-chapter problems, for which no answers are provided, but, in such a textbook, I feel that it is not really necessary to work through them to gain a solid grasp of the material presented.
Physically, the book is much more attractive than the previous edition. The cover is more appealling, and the text is well set in a two-colour print. The diagrams are nothing special, but they are generally clear and explain their point well, and are certainly much improved from the first edition, especially those in the fabrication section.
Just a final comment on other reviews: it is difficult to see how this book may be regarded as a bible of any sort, for the material is covered in quite a superficial manner. I wonder if they are not mistaking it for the 'big Sze', viz., Sze's 'Physics of Semiconductor Devices', which is another, much larger and more comprehensive, work of Sze's.
