One of the pad structures provides a plurality of recessed pad areas which are formed in a single aluminum pad. An oxide mesa can he provided under the aluminum pad. Another pad structure provides a single recessed pad area which is formed in a single aluminum pad, and the aluminum pad is disposed above a copper pad and a plurality of trench/via pads.

Abstract: A method to maintain a well-defined gate stack profile, deposit or grow a uniform gate dielectric, and maintain gate length CD control by means of an inert insulating liner deposited after dummy gate etch and before the spacer process. The liner material is selective to wet chemicals used to remove the dummy gate oxide thereby preventing undercut in the spacer region. The method is aimed at making the metal gate electrode technology a feasible technology with maximum compatibility with the existing fabrication environment for multiple generations of CMOS transistors, including those belonging to the 65 nm, 45 nm and 25 nm technology nodes, that are being used in analog, digital or mixed signal integrated circuit for various applications such as communication, entertainment, education and security products.

Abstract: A pad structure and passivation scheme which reduces or eliminates IMC cracking in post wire bonded dies during Cu/Low-k BEOL processing. A thick 120 nm barrier layer can be provided between a 1.2 ?m aluminum layer and copper. Another possibility is to effectively split up the barrier layer, where the aluminum layer is disposed between the two barrier layers. The barrier layers may be 60 nm while the aluminum layer which is disposed between the barrier layers may be 0.6 ?m. Another possibility is provide an extra 0.6 ?m aluminum layer on the top barrier layer. Still another possibility is to provide an extra barrier layer on the top-most aluminum layer, such that a top barrier layer of 60 nm is provided on a 0.6 ?m aluminum layer, followed by another harrier layer of 60 nm, another aluminum layer of 0.6 ?m and another barrier layer of 60 nm.

Abstract: The present invention is directed to methods of fabricating a high-K dielectric films having a high degree of crystallographic alignment at grain boundaries of the film. A disclosed method involves providing a substrate and then depositing a high-K dielectric material assisted with an ion beam to enable the preferential formation of crystal lattices having a selected crystallographic orientation. The resultant dielectric films have a high degree of crystallographic alignment at grain boundaries. Another disclosed method involves providing a substrate and then angularly depositing a material onto the substrate in order to assist in the preferential formation of crystal lattices having a selected crystallographic orientation. The result is a dielectric film having a high degree of crystallographic alignment at grain boundaries of the film.

Abstract: A method of forming a self-aligned logic cell. A nanotube layer is formed over the bottom electrode. A clamp layer is formed over the nanotube layer. The clamp layer covers the nanotube layer, thereby protecting the nanotube layer. A dielectric layer is formed over the clamp layer. The dielectric layer is etched. The clamp layer provides an etch stop and protects the nanotube layer. The clamp layer is etched with an isotropic etchant that etches the clamp layer underneath the dielectric layer, creating an overlap of the dielectric layer, and causing a self-alignment between the clamp layer and the dielectric layer. A spacer layer is formed over the nanotube layer. The spacer layer is etched except for a ring portion around the edge of the dielectric layer.

Abstract: A method for redirecting void diffusion away from vias in an integrated circuit design includes steps of forming an electrical conductor in a first electrically conductive layer of an integrated circuit design, forming a via between a distal end of the electrical conductor and a second electrically conductive layer of the integrated circuit design, and reducing tensile stress in the electrical conductor to divert void diffusion away from the via.

Abstract: Different ways to reduce or eliminate the IMC cracking issues in wire bonded parts, including: changing to more compressive dielectric films for top, R1, and R2; changing the top passivation film stacks to more compressive films; changing the low k film to a higher compressive film; reducing the R layer thickness and pattern density to reduce tensile stress; and minimizing anneal and dielectric deposition temperatures. Each of the methods can be used individually or in combination with each other to reduce overall tensile stresses in the Cu/low-k wafer thus reducing or eliminating the IMC cracking issue currently seen in the post wire bonded parts.

Abstract: A method of forming a metal gate in a wafer. PolySi1-xGex and polysilicon are used to form a tapered groove. Gate oxide, PolySi1-xGex, and polysilicon is deposited on a wafer. A resist pattern is formed. A portion of the polysilicon, PolySi1-xGex, and gate oxide is removed to provide a tapered profile. The resist is removed; a dielectric liner is deposited, and then at least a portion of the dielectric liner is removed, thereby exposing the polysilicon and leaving the dielectric liner in contact with the polysilicon, PolySi1-xGex, and gate oxide. A dielectric is deposited, and a portion is removed thereby exposing the polysilicon. The polysilicon, PolySi1-xGex, and gate oxide is removed from inside the dielectric liner, thereby leaving a tapered gate groove. Metal is then deposited in the groove.
