    A novel composite bump, Smart bump, structure has been successfully developed for chip-on-glass (COG) package using non-conductive adhesive film (NCF). We have successfully verified the low contact resistance and high reliabilities using Smart bump and COG NCF process for the packages of 17"W, 12.1" and 2.4" TFT-LCD modules. We have realized that COG NCF process with Smart bump is simpler and lower cost in consumable materials than the conventional COG ACF process with Au bump. The COG NCF process also allows fine-pitch-driver package for high-resolution TFT-LCDs, and has a higher process yield in pilot production.
