  • Patent number: 12684767
    Abstract: The disclosure provides a structure with a buried doped region for coupling a source line contact to the gate structure of a memory cell. A structure according to the disclosure includes a memory cell having a gate structure extending in a first lateral direction over a substrate. A buried doped region is within the substrate and extends in a second lateral direction from below the gate structure to a portion of the substrate laterally distal to the gate structure. A source line contact is on the portion of the substrate laterally distal to the gate structure. The buried doped region couples the source line contact to the gate structure of the memory cell through a lower surface of the gate structure.

  • Publication number: 20260127345
    Abstract: The present disclosure relates to a method for developing a design of an electronic circuit system in one or more Electronic Design Automation (EDA) environments. The method comprises: receiving data indicative of an event related to a specific point in time during development of the design of the electronic circuit system using a first software tool. A development action may be determined based on the event. Design data descriptive of a state of the design at the point in time, and a library setup descriptive of libraries used by the first software tool to provide the design at that state may be determined. A design snapshot data structure comprising entries representing the design data and the library setup may be created. The design snapshot data structure may be shared with a second software tool for enabling execution of the development action using the second software tool.

  • Patent number: 12600857
    Abstract: A mixture contains at least one amino-regulated polyether block amide (PEBA) and at least one poly(meth)acrylate selected from poly(meth)acrylimides, polyalkyl(meth)acrylates, and mixtures thereof. The mass ratio of PEBA to poly(meth)acrylate is 95:5 to 60:40. The polyalkyl(meth)acrylate contains 80% by weight to 99% by weight of methyl methacrylate (MMA) units and 1% by weight to 20% by weight of C1-C10-alkyl acrylate units, based on the total weight of polyalkyl(meth)acrylate. The mixture can be processed to give foamed mouldings. The mouldings can be used in footwear soles, stud material, insulation or insulating material, damping components, lightweight components, or in a sandwich structure.

  • Patent number: 12557330
    Abstract: Disclosed are embodiments of a semiconductor device and method of forming the device. The device includes a gate with first and second sections on a semiconductor layer. The first section includes first gate dielectric and gate conductor layers and an optional additional gate conductor layer on the first gate conductor layer. The second section includes second gate dielectric and gate conductor layers on the semiconductor layer and further extending onto the top of the first gate conductor layer.

  • Publication number: 20240343901
    Abstract: Polymer compositions are made based on imidated polyalkyl (meth)acrylate, especially imidated polymethyl methacrylate. The polymer composition includes a polymer matrix A and at least one tribological additive B, especially selected from organic or inorganic solid hardening particles. The polymer compositions and formed articles made thereof exhibit low friction coefficients and high wear resistance even at elevated temperatures. They can advantageously be used in tribological application, in replacement of high-performance materials, such as polyether ether ketone (PEEK).
