    摘要: A multi-tiered IC device contains a first die including a substrate with a first and second set of vias. The first set of vias extends from one side of the substrate, and the second set of vias extend from an opposite side of the substrate. Both sets of vias are coupled together. The first set of vias are physically smaller than the second set of vias. The first set of vias are produced prior to circuitry on the die, and the second set of vias are produced after circuitry on the die. A second die having a set of interconnects is stacked relative to the first die in which the interconnects couple to the first set of vias.

    摘要: An interconnect sensor for detecting delamination due to coefficient of thermal expansion mismatch and/or mechanical stress. The sensor comprises a conductive path that includes a via disposed between two back end of line metal layers separated by a dielectric. The via is coupled between a first probe structure and a second probe structure and mechanically coupled to a stress inducing structure. The via is configured to alter the conductive path in response to mechanical stress caused by the stress inducing structure. The stress inducing structure can be a through silicon via or a solder ball. The dielectric material can be a low-k dielectric material. In another embodiment, a method of forming an interconnect sensor is provided for detecting delamination.

    摘要: 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. The nanotube layer is etched except for portions that are underlying at least one of the clamp layer, the dielectric layer, and the spacer layer, thereby causing a self-alignment between the clamp layer, the overlap to the dielectric layer, the spacer layer, and the nanotube layer.

    摘要: A method for patterning CNTs on a wafer wherein a CNT layer is provided on a substrate, a hard mask film is deposited on the CNT layer, a BARC layer (optional) is coated on the hard mask film, and a resist is patterned on the BARC layer (or directly on the hard mask film if the BARC layer is not included). Then, the resist pattern is effectively transferred to the hard mask film by etching the BARC layer (if provided) and etching partly into, but not entirely through, the hard mask film (i.e., etching is stopped before reaching the CNT layer). Then, the resist and the BARC layer (if provided) is stripped, and the hard mask pattern is effectively transferred to the CNTs by etching away (preferably by using C1, F plasma) the portions of the hard mask which have been already partially etched away.

    摘要: The cost associated with alignment in a stacked IC device can be reduced by aligning multiple die instead of a single die during the alignment step. In one embodiment, the alignment structures are placed in the scribe line instead of within the die itself. Aligning four die instead of one eliminates the need for as many alignment indicators and thus more silicon on the wafer can be used for active areas. In addition, this method allows for yield improvement through binning of dies having the same yield configuration.

    摘要: A micro-electro-mechanical systems (MEMS) pixel for display and touch position sensing includes a substrate and a capacitive element. The capacitive element includes one or more pixels having a first conductive platelet above the substrate, and a second conductive platelet above and spaced apart from the first conductive platelet, the two platelets forming the capacitive element. A connection to each platelet provides for applying a voltage, wherein the platelet separation changes according to the applied voltage. A transparent dielectric plate, spaced apart from and positioned opposite the substrate, covers the at least one pixel. A capacitance sensing circuit attached to the connection to each platelet of the pixel senses changes in capacitance not resulting from the applied voltage.
