Increasing the Transistor Count by Constructing a Two-Layer Crystal Square on a Single Chip

According to the Moore's law, the number of transistor should be doubled every 18 to 24 months. The main factors of increasing the number of transistor are: a density and a die size. Each of them has a serious physical limitation; the first one "density" may be reached "Zero" after few years, which causes limitation in performance and speed of a microprocessor, the second one "die size" cannot be increased every 2 years, it must be fixed for several years, otherwise it will affect the economical side. This article aims to increase the number of transistors, which increase the performance and the speed of the microprocessor without or with a little bit increasing the die size, by constructing a two-layer crystal square for transistors, which allows increasing the number of transistors two additional times. By applying the new approach the number of transistors in a single chip will be approximately doubled every 24 months according to Moore's Law without changing rapidly the size of a chip (length and width), only the height of a chip must be changed for putting the two layers.
