Abstract

Techniques are provided herein to form a semiconductor diode device within an integrated circuit. In an example, a diode device includes separate fins or bodies of semiconductor material that are separated by an insulating barrier. One of the fins or bodies is doped with n-type dopants while the other fin or body is doped with p-type dopants. Each of the first and second fins or bodies includes an epitaxially grown region over it that includes the corresponding dopant type with a higher dopant concentration. Additionally, each of the first and second fins or bodies includes another epitaxially grown region on the backside (e.g., under the fins or bodies) of the corresponding dopant type with a lower dopant concentration compared to the epitaxial regions on the opposite side of the fins or bodies. An undoped or lightly doped layer may also be formed between the epitaxially grown regions on the backside.
