Abstract: A method is described for fabricating and antifuse structure (100) integrated with a semiconductor device such as a FINFET or planar CMOS devise. A region of semiconducting material (11) is provided overlying an insulator (3) disposed on a substrate (10); an etching process exposes a plurality of corners (111-114) in the semiconducting material. The exposed corners are oxidized to form elongated tips (111t-114t) at the corners; the oxide (31) overlying the tips is removed. An oxide layer (51), such as a gate oxide, is then formed on the semiconducting material and overlying the corners; this layer has a reduced thickness at the corners. A layer of conducting material (60) is formed in contact with the oxide layer (51) at the corners, thereby forming a plurality of possible breakdown paths between the semiconducting material and the layer of conducting material through the oxide layer.

A gate dielectric (30) and a gate electrode (40) are formed over the gate region. Current flows between the source node and the drain node when the predetermined bias is applied to both the drain node and the gate electrode.

Also included is a spiral shaped capacitor electrode which lends itself to modular design by offering a wide range of discrete capacitive values easily specified by the circuit designer.
