    摘要: An E-fuse and a method for fabricating an E-fuse are provided integrating polysilicon resistor masks. The E-fuse includes a polysilicon layer defining a fuse shape including a cathode, an anode, and a fuse neck connected between the cathode and the anode silicide formation. A silicide formation is formed on the polysilicon layer with an unsilicided portion extending over a portion of the cathode adjacent the fuse neck. The unsilicided portion substantially prevents current flow in the silicide formation region of the cathode, with electromigration occurring in the fuse neck during fuse programming. The unsilicided portion has a substantially lower series resistance than the series resistance of the fuse neck.

    摘要: Electrically programmable fuse structures and methods of fabrication thereof are presented, wherein a fuse includes first and second terminal portions interconnected by an elongate fuse element. The first terminal portion has a maximum width greater than a maximum width of the fuse element, and the fuse includes a narrowed width region where the first terminal portion and fuse element interface. The narrowed width region extends at least partially into and includes part of the first terminal portion. The width of the first terminal portion in the narrowed region is less than the maximum width of the first terminal portion to enhance current crowding therein. In another implementation, the fuse element includes a restricted width region wherein width of the fuse element is less than the maximum width thereof to enhance current crowding therein, and length of the restricted width region is less than a total length of the fuse element.

    摘要: Semiconductor methods and device structures for suppressing latch-up in bulk CMOS devices. The method comprises forming a trench in the semiconductor material of the substrate with first sidewalls disposed between a pair of doped wells, also defined in the semiconductor material of the substrate. The method further comprises forming an etch mask in the trench to partially mask the base of the trench, followed by removing the semiconductor material of the substrate exposed across the partially masked base to define narrowed second sidewalls that deepen the trench. The deepened trench is filled with a dielectric material to define a trench isolation region for devices built in the doped wells. The dielectric material filling the deepened extension of the trench enhances latch-up suppression.

    摘要: Methods of forming a semiconductor structure having FinFET's and planar devices, such as MOSFET's, on a common substrate by a damascene approach. A semiconductor fin of the FinFET is formed on a substrate with damascene processing in which the fin growth may be interrupted to implant ions that are subsequently transformed into a region that electrically isolates the fin from the substrate. The isolation region is self-aligned with the fin because the mask used to form the damascene-body fin also serves as an implantation mask for the implanted ions. The fin may be supported by the patterned layer during processing that forms the FinFET and, more specifically, the gate of the FinFET. The electrical isolation surrounding the FinFET may also be supplied by a self-aligned process that recesses the substrate about the FinFET and at least partially fills the recess with a dielectric material.

    摘要: Methods of forming semiconductor structures characterized by a thin active silicon layer on an insulating substrate by a crystal imprinting or damascene approach. The methods include patterning an insulating layer to define a plurality of apertures, filling the apertures in the patterned insulating layer with amorphous silicon to define a plurality of amorphous silicon features, and re-growing the amorphous silicon features to define a thin active silicon layer consisting of regrown silicon features. The amorphous silicon features may be regrown such that a number have a first crystal orientation and another number have a different second crystal orientation.
