摘要： Disclosed are secure anti-fuse one-time programmable (OTP) bit cells. In an aspect, an OTP bit cell includes a P− well comprising an N+ region and a P+ region, a first contact electrically coupled to the N+ region of the P− well, a second contact electrically coupled to the P+ region of the P− well, an insulating layer disposed over a portion of the N+ region, a portion of the P− well, and a portion of the P+ region, a gate structure disposed over the insulating layer, and a third contact electrically coupled to the gate structure. In an unprogrammed mode, the insulating layer creates a high resistance between the third contact and the second contact, and in a programmed mode, a rupture in the insulating layer creates a low resistance between the third contact and the second contact.

摘要： A one-time programmable (OTP) fuse includes a fuse link including a thin film resistor (TFR) layer between a first insulator layer and a second insulator layer. A first terminal of the OTP fuse includes a first conductive pillar through one of the first and second insulator layers and in contact with the TFR layer; and a second terminal of the OTP fuse includes a second conductive pillar through one of the first and second insulator layers and in contact with the TFR layer. The second conductive pillar and the TFR layer have a lateral contact interface having a same shape as an outer portion of the second conductive pillar. The second conductive pillar does not simply land on the TFR layer, but extends through it. Application of a current to the OTP fuse results in programming via rupture of the lateral contact interface (not electromigration in the fuse link).
