    摘要: Disclosed are embodiments of a method that both monitors patterning integrity of etched openings (i.e., ensures that lithographically patterned and etched openings are complete) and forms on-chip conductive structures (e.g., contacts, interconnects, fuses, anti-fuses, capacitors, etc.) within such openings. The method embodiments incorporate an electro-deposition process to provide both the means by which pattern integrity of etched openings can be monitored and also the metallization required for the formation of conductive structures within the openings. Specifically, during the electro-deposition process, electron flow is established by applying a current to the back side of the semiconductor wafer, thus, eliminating the need for a seed layer. Electron flow through the wafer and into the electroplating solution is then monitored and used as an indicator of electroplating in the etched openings and, thereby, as an indicator that the openings are completely etched.

    摘要: A method is provided for making a bipolar transistor which includes a tapered, i.e. frustum-shaped, collector pedestal having an upper substantially planar surface, a lower surface, and a slanted sidewall extending between the upper surface and the lower surface, the upper surface having substantially less area than the lower surface. The collector pedestal can be formed on a surface of a collector active region exposed within an opening extending through first and second overlying dielectric regions, where the opening defines vertically aligned edges of the first and second dielectric regions.

    摘要: Electrically programmable fuse structures for an integrated circuit and methods of fabrication thereof are presented, wherein the electrically programmable fuse has a first terminal portion and a second terminal portion interconnected by a fuse element. The first terminal portion and the second terminal portion reside over a first support and a second support, respectively, with the first support and the second support being spaced apart, and the fuse element bridging the distance between the first terminal portion over the first support and the second terminal portion over the second support. The fuse, first support and second support define a α-shaped structure in elevational cross-section through the fuse element. The first terminal portion, second terminal portion and fuse element are coplanar, with the fuse element residing above a void, which in one embodiment is filed by a thermally insulating dielectric material that surrounds the fuse element.

    摘要: A voltage divider for integrated circuits that does not include the use of resistors. In one embodiment, voltage node VDD is connected with two n-type transistors, NFET1 and NFET2, which are connected in series. NFET 1 includes a source (12), a drain (14), a gate electrode (16) having a gate area A1 (not shown), and a p-substrate (18). NFET2 includes a source (20), a drain (22), a gate electrode (24) having a gate area A2 (not shown), and a p-substrate (26). Source (12) and drain (14) of NFET1 are coupled with gate electrode (24) of NFET2. The voltage difference between NFET1 and NFET2 has a linear function with VDD. As a result, voltage VDD may be divided between NFET1 and NFET2 by properly choosing the ratio between each of the respective transistor gate electrode areas, (A1) and (A2).

    摘要: A structure and method for providing an antifuse which is closed by laser energy with an electrostatic assist. Two or more metal segments are formed over a semiconductor structure with an air gap or a porous dielectric between the metal segments. Pulsed laser energy is applied to one or more of the metal segments while a voltage potential is applied between the metal segments to create an electrostatic field. The pulsed laser energy softens the metal segment, and the electrostatic field causes the metal segments to move into contact with each other. The electrostatic field reduces the amount of laser energy which must be applied to the semiconductor structure to close the antifuse.

    摘要: An inverse-T transistor is formed by a method that decouples the halo implant, the deep S/D implant and the extension implant, so that the threshold voltage can be set by adjusting the halo implant without being affected by changes to the extension implant that are intended to alter the series resistance of the device. Formation of the inverse-T structure can be made by a damascene method in which a temporary layer deposited over the layer that will form the cross bar of the T has an aperture formed in it to hold the gate electrode, the aperture being lined with vertical sidewalls that provide space for the ledges that form the T. Another method of gate electrode formation starts with a layer of poly, forms a block for the gate electrode, covers the horizontal surfaces outside the gate with an etch-resistant material and etches horizontally to remove material above the cross bars on the T, the cross bars being protected by the etch resistant material.
