  • Patent number: 11985906
    Abstract: A magnetic tunnel junction (MTJ) memory cell and a metallic etch mask portion are formed over a substrate. At least one dielectric etch stop layer is deposited over the metallic etch mask portion, and a via-level dielectric layer is deposited over the at least one dielectric etch stop layer. A via cavity may be etched through the via-level dielectric layer, and a top surface of the at least one dielectric etch stop layer is physically exposed. The via cavity may be vertically extended by removing portions of the at least one dielectric etch stop layer and the metallic etch mask portion. A contact via structure is formed directly on a top surface of the top electrode in the via cavity to provide a low-resistance contact to the top electrode.

  • Patent number: 11983370
    Abstract: A two dimensional touch sensor panel can be thermoformed or curved by another process to a three-dimensional touch sensor panel, and the three-dimensional touch sensor panel can be laminated to a three-dimension surface having a highly curved or spherical shape. In some examples, thermoforming a two-dimensional touch sensor panel into a three-dimensional touch sensor panel can result in strain of the touch electrodes, and can result in non-uniform three-dimensional touch electrodes (distortion of the two-dimensional touch electrode pattern). The strain can be a function of the curved touch-sensitive surface and/or process related mechanical strain from thermoforming. In some examples, a three-dimensional touch sensor panel can be formed with uniform area touch electrodes using a two-dimensional touch sensor panel pattern with non-uniform area touch electrodes in accordance with the strain pattern expected for a given curved surface and thermoforming technique.

  • Patent number: 11980544
    Abstract: A holder for a hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a non-expandable, non-compressible prosthetic valve and a self-expandable anchoring stent, thereby enabling attachment to the annulus without sutures. A first suture connects the holder to the valve and constricts an inflow end of the anchoring stent. A second suture connects the holder to the valve and extends down three holder legs to loop through fabric on the valve. Both sutures may loop over a single cutting well on the holder so that severing the first and second sutures at the single cutting well simultaneously releases the tension in the first suture, permitting the inflow end of the anchoring stent to expand, and disconnects the valve holder from the prosthetic heart valve.

  • Publication number: 20240153843
    Abstract: A package structure is provided. The package structure includes a semiconductor die and a thermoelectric structure disposed on the semiconductor die. The thermoelectric structure includes P-type semiconductor blocks, N-type semiconductor blocks and metal pads. The P-type semiconductor blocks and the N-type semiconductor blocks are arranged in alternation with the metal pads connecting the P-type semiconductor blocks and the N-type semiconductor blocks. When a current flowing through one of the N-type semiconductor block, one of the metal pad, and one of the P-type semiconductor block in order, the metal pad between the N-type semiconductor block and the P-type semiconductor block forms a cold junction which absorbs heat generated by the semiconductor die.
