  • Publication number: 20250098187
    Abstract: A memory cell structure includes a transistor structure and a capacitor structure, where the capacitor structure includes a hydrogen absorption layer. The hydrogen absorption layer absorbs hydrogen, which prevents or reduces the likelihood of the hydrogen diffusing into an underlying metal-oxide channel of the transistor structure. In this way, the hydrogen absorption layer minimizes and/or reduces the likelihood of hydrogen contamination in the metal-oxide channel, which may enable a low current leakage to be achieved for the memory cell structure and reduces the likelihood of data corruption and/or failure of the memory cell structure, among other examples.

  • Publication number: 20250087491
    Abstract: A method includes forming a gate stack, growing a source/drain region on a side of the gate stack through epitaxy, depositing a contact etch stop layer (CESL) over the source/drain region, depositing an inter-layer dielectric over the CESL, etching the inter-layer dielectric and the CESL to form a contact opening, and etching the source/drain region so that the contact opening extends into the source/drain region. The method further includes depositing a metal layer extending into the contact opening. Horizontal portions, vertical portions, and corner portions of the metal layer have a substantially uniform thickness. An annealing process is performed to react the metal layer with the source/drain region to form a source/drain silicide region. The contact opening is filled to form a source/drain contact plug.

  • Patent number: 11984089
    Abstract: The present invention provides improved driving methods for four particle electrophoretic displays that improves the performance of such displays when they are deployed in low temperature environments and the displays are required to be updated when positioned vertically (i.e., the driving electric fields are substantially perpendicular to the direction of Earth's gravity). Methods are provided for displaying each of the colors at each pixel, as desired, with minimal interference (contamination) from the other particles.

  • Patent number: 11984090
    Abstract: The present invention provides four-particle electrophoretic displays with improved driving methods to achieve better color separation between adjacent pixel electrodes. The driving methods improve the color state performance when a first pixel is displaying a mixed state of a first highly-charged particle and a second lower-charged particle of the opposite polarity, while a neighboring pixel is displaying a state of a second highly-charged particle having the opposite polarity to the first highly-charged particle. The particles can be, for example, all reflective or one type of particle can be partially light transmissive.

  • Publication number: 20230097643
    Abstract: A high electron mobility transistor comprising a nucleation layer having a first lattice constant, a back-barrier layer having a second lattice constant and a stress management layer having a third lattice constant which is larger than both first and second lattice constants. The stress management layer compensates some or all of the stress due to the lattice mismatch between the nucleation layer and back barrier layer so that the resulting structure experiences less bow and warp.
