2nd Edition
Handbook of Semiconductor Interconnection Technology
First introduced about a decade ago, the first edition of the Handbook of Semiconductor Interconnection Technology became widely popular for its thorough, integrated treatment of interconnect technologies and its forward-looking perspective. The field has grown tremendously in the interim and many of the "likely directions" outlined in the first edition are now standard in modern facilities. Reflecting those advances, this edition delves into the practical aspects of interconnections for manufacturing. It examines the interconnect and fabrication technologies now available, with an examination of future prospects for the field.
