However, the inventors have found that the reduction of cost in the stacking process and the increase in the degree of freedom of selecting the memory LSI to be stacked are required for a simple stacking of processor LSIs and memory LSIs as so far practiced. An external communication LSI including a circuit for performing the communication with the outside of the stacked LSI at a high rate of more than 1 GHz; a processor LSI including a general purpose CPU etc.; and a memory LSI including a DRAM etc. are stacked in this order and those LSIs are connected with one another with a through silicon via to enable a high speed and high volume communication at a shortest path.

  • Publication number: 20100059748
    Abstract: Application form of and demand for an IC chip formed with a silicon wafer are expected to increase, and further reduction in cost is required. An object of the invention is to provide a structure of an IC chip and a process capable of producing at a lower cost. In view of the above described object, one feature of the invention is to provide the steps of forming a separation layer over an insulating substrate and forming a thin film integrated circuit having a semiconductor film as an active region over the separation layer, wherein the thin film integrated circuit is not separated. There is less limitation on the shape of a mother substrate in the case of using the insulating substrate, when compared with the case of taking a chip out of a circular silicon wafer. Accordingly, reduction in cost of an IC chip can be achieved.
