Abstract: In some implementations, one or more semiconductor processing tools may form a metal cap on a metal gate. The one or more semiconductor processing tools may form one or more dielectric layers on the metal cap. The one or more semiconductor processing tools may form a recess to the metal cap within the one or more dielectric layers. The one or more semiconductor processing tools may perform a bottom-up deposition of metal material on the metal cap to form a metal plug within the recess and directly on the metal cap.

Abstract: An antifuse-type non-volatile memory and a control method for the antifuse-type non-volatile memory are provided. During a program action of a program cycle, a timing controller generates a timing control signal. According to the timing control signal, a word line driver is controlled to provide an on voltage and an off voltage to an activated word line. In a total time period of plural on periods, the program current is sufficient to rupture a gate oxide layer of an antifuse transistor in the selected memory cell, and a heating process is completed. Consequently, the gate oxide layer of the antifuse transistor is in a solid rupture state. Consequently, the program action can be successfully performed on the selected memory cell.
