3-D ICs

ABSTRACT

The unprecedented growth of the computer and the Information technology industry is demanding Very Large Scale Integrated (VLSI) circuits with increasing functionality and performance at minimum cost and power dissipation. VLSI circuits are being aggressively scaled to meet this Demand, which in turn has some serious problems for the semiconductor industry.

Additionally heterogeneous integration of different technologies in one single chip (SoC) is becoming increasingly desirable, for which planar (2-D) ICs may not be suitable.

3-D ICs are an attractive chip architecture that can alleviate the interconnect related problems such as delay and power dissipation and can also facilitate integration of heterogeneous technologies in one chip (SoC). The multi-layer chip industry opens up a whole new world of design. With the Introduction of 3-D ICs, the world of chips may never look the same again.
