Abstract
A novel method of fabricating a double-gate MOSFET structure is disclosed. The method utilizes selective lateral epitaxial growth of silicon into a thin gap formed between two sacrificial dielectric films for accurate thickness control. The sacrificial films are then replaced by a gate material (e.g., polysilicon) such that top and bottom gates are self-aligned to each other and to the channel region. Also disclosed is a self-aligned double-gate MOSFET constructed in accordance with the foregoing method.
