This book is extremely well illustrated. It is a pleasure thumbing through the book and learning something in a new area just by looking at all the diagrams and pictures. However, the discussions of semiconductor devices are pretty sketchy, and formula derivations are mostly non-existent. For example, the book gives expressions for the different mobility limits for ionized impurity and phonon scattering, but does not derive any of them like Seeger would, although references are given. Unlike the Seeger classic, in its 9th edition, where new topics kind of look like they were just thrown in, this book has a more coherent integrated treatment of "new" topics with the older classical topics. If you want in-depth discussions, you will likely be disappointed. However, if you are looking for a broad survey of modern areas of interest in semiconductor physics and technology, with lots of well-chosen figures and diagrams, this is a fine book.
