Abstract:
A method of fabricating a body tied to source transistor, comprising the steps of:(a) forming a semiconductor body region; (b) forming a gate and sidewall spacers; (c) forming at least one halo diffusion which is aligned to said gate and has the same conductivity type as said body region; (d) forming LDD/MDD regions with conductivity type opposite to said body region; (e) doping a body-tie diffusion with the same conductivity as the body, (f) forming source and drain diffusion with a conductivity type opposite to that of said body; and (g) cladding said source, drain, and body-tie diffusion with a material of metallic conductivity, to thereby form an ohmic connection between said source diffusion and said body-tie diffusion.
