Applying the Moore's Law for a Long Time using Multi-Layer Crystal Square on a Chip

Abstract

Increasing the speed of a CPU and improving its performance play the main role in the design and architecture of each new generation of a microprocessor. Many factors are affected on the increasing of the CPU's speed, the main important one is the number of transistors on a chip; more transistors, more speed. Relating to Moore's law, the number of transistors should be increased twice every two years approximately. Some limitations effect on the increasing the number of transistors such as the die size, density of transistors, design complexity and others. This article introduces a new approach to delay these limitations; this allows applying the Moore's law for more years in future. The basic idea is to increase the number of transistors on a chip by manufacturing a multi-layer crystal square where the transistors can be fitted, in this case Moore's law can be applied as much as possible every 24 months by increasing the transistor count. Applying this approach needs to change the height of a chip for the two or more layers, this delays the changing in the design complexity and/or density of transistors in a crystal square and the changing in the die size.
