ONE-TIME PROGRAMMABLE DEVICE WITH ANTIFUSE

Abstract:

Certain aspects of the present disclosure generally relate to a one-time programmable (OTP) device including an antifuse device. The antifuse device generally includes a first active region, a second active region, a channel region disposed between the first active region and the second active region, a gate region disposed above the channel region, and a first set of lightly doped drain (LDD) extension regions extending partially across the channel region from the first active region and the second active region and extending into a portion of the channel region underneath the gate region. The first set of LDD extension regions have a same dopant type as the gate region and at least one of the first active region or the second active region.
