Abstract:
A pair of directly coupled Field Effect Transistors (FETs) comprising:a first layered epitaxial stack having a channel layer of a first conduction type between a pair of layers of a second conduction type;a second layered epitaxial stack having a channel layer of one of said first conduction type and said second conduction type between a pair of layers of the other of said first conduction type and said second conduction type; anda gate insulator layer between said first and second epitaxial stacks,one layer in said pair of layers in each of said first and said second layered epitaxial stacks being thicker Man the other layer in said pair, each of said channel layers in said epitaxial stacks having a surface facing said thicker layer of the other said epitaxial stack and separated therefrom by said gate insulator, whereby said thicker layer of said first layered epitaxial stack is a gate of the second layered epitaxial stack, and said thicker layer of said second layered epitaxial stack is a gate of the first layered epitaxial stack, andwherein a height of said first layered epitaxial stack is same as a height of said second layered epitaxial stack.
