Abstract

An integrated circuit (10) has a vertical device, such as a transistor (71), formed by epitaxial growth from a substrate (12) and a horizontal device, such as a transistor (73, 75) grown epitaxially from the vertical device. In accordance with one embodiment of the invention, all six transistors of an SRAM cell can be formed in single crystal material for improved device characteristics and increased cell density. Utilization of various combinations of vertical and horizontal devices permits a large degree of vertical integration within semiconductor devices.
