Patent ID: 6855988

Claim:
A switching device comprising: a first device having a conducting path coupled between a first supply voltage and a common output; a second device having a conducting path coupled between a second supply voltage and said common output; and a common input to control said first and second devices; wherein said conducting paths of first and second devices comprises a single geometry of a very thin semiconductor material having a thickness t P1 in Angstroms; and wherein each of said conducing paths of the first and second devices comprises a hub region; and wherein each of said hub regions is designed to contain the entire surface inversion layer within said thickness t P1 during the conducting mode by satisfying the condition: 1/( D*t P1 2 )< X Angstroms; and wherein each of said hub regions is designed to be fully depleted of majority carriers inside said thickness t P1 to eliminate a floating body region during the conducting mode by satisfying the condition: 1/( D*t P1 2 )>0.5 *X/Ln ( D/N 1 ) Angstroms; where, X is a thickness parameter in Angstroms defined by X=q 2 /(2*kT*ε S ), q is the electron charge, kT/q is the thermal voltage, ε S is the permittivity of the semiconductor material in each hub region, D is the doping in each hub region in Atoms/Angstroms 3 , and N i is the intrinsic carrier concentration of the semiconductor material in Atoms/Angstroms 3 .
