Abstract :
We have proposed a new three-dimensional (3D) integration technology based on a chip-to-wafer bonding method which is called a super chip integration technology. Various kinds of chips such as processor chip, memory chips, analog IC chip and sensor chips which are fabricated by different technologies can be vertically stacked into a 3D LSI chip by using a super chip integration technology. Such 3D LSI chip is called a super chip. Various kinds of chips with different chip size, chip thickness and material can be vertically stacked in the super chip integration technology. To establish the super chip integration technology, several key technologies of vertical interconnection formation, chip alignment and bonding, adhesive injection, and chip thinning and planarization were developed. By using the super chip integration technology, three-layer stacked LSI chips with vertical interconnections were successfully fabricated
