Abstract: Damascene or non-damascene processing when used with a method that includes (a) forming a mask having an opening therethrough on a structure, said opening having sidewalls; (b) implanting an inhibiting species into said structure through the opening so as to form an inhibiting region in said structure; and (c) growing a dielectric layer on the structure in said opening, wherein the inhibiting region partially inhibits growth of the dielectric layer is capable of forming a semiconductor structure, e.g., MOSFET or anti-fuse, including a dual thickness dielectric layer. Alternatively, the dual thickness dielectric can be formed by replacing the inhibiting species mentioned above with a dielectric growth enhancement species which forms an enhancing region in the structure which aids in the growth of the dielectric layer.

Abstract: A universal fuse latch device includes a latch circuit receiving an electrical signal for initializing the latch circuit to a first state; one or more legs connected at the latch node, with a first leg implementing a fuse type element capable of transitioning the latch from the first state to a second state; and a second leg including an anti-fuse type element, wherein the fuse latch is provided with a fuse resistance trip point to ensure adequate reading of one of the fuse and anti-fuse type elements. The universal fuse latch device may be part of a programmable fuse bank including a plurality of information fuse latches for storing redundancy information in a memory system and capable of being simultaneously interrogated. A master fuse control device comprising the universal fuse latch circuit is programmed in accordance with a priority of legs to be interrogated in the information fuse latches.

Abstract: Described is an antifuse array comprising a plurality of antifuse elements and a plurality of cell plates. Each of the antifuse elements comprises a programming transistor and one of the cell plates. The programming transistor and the cell plate of each antifuse element are both activated to program the antifuse element. Each of the cell plates is coupled to a portion of the plurality of antifuse elements and to one of a plurality of decode circuits, and the decode circuits selectively activate its coupled cell plate. With a preferred embodiment, a multitude of interconnect lines are connected to the antifuses and in particular, each interconnect line intersects each of the cell plates and is associated with one antifuse in each group of antifuses. With this preferred embodiment, the array of antifuses are decoded by predecoding one of the cell plates by elevating the cell plate voltage from ground to a program voltage, and decoding one of the interconnect lines to program one of the antifuses.
