Abstract:
1. A method of fabricating a MOS transistor with a controllable and modulatable conduction path through a dielectric oxide layer, said transistor structure comprising said dielectric oxide layer formed between two silicon plates having surfaces, wherein, said silicon plates overhang said dielectric oxide layer all around to define an undercut having a substantially rectangular cross-sectional shape, said method comprising the steps of: chemically altering respective surfaces of said silicon plates defining said undercut to provide at said undercut first functional groups; chemically altering respective surfaces of said silicon plates outside of said undercut to provide second functional groups; and selectively reacting said first functional groups provided at said undercut with an organic molecule having ends and a reversibly reducible center, thereby establishing a covalent bond to each end of said organic molecule.
