  • Publication number: 20240162313
    Abstract: A method for forming a high electron mobility transistor is disclosed. A mesa structure having a channel layer and a barrier layer is formed on a substrate. The mesa structure has two first edges extending along a first direction and two second edges extending along a second direction. A passivation layer is formed on the substrate and the mesa structure. A first opening and a plurality of second openings connected to a bottom surface of the first opening are formed and through the passivation layer, the barrier layer and a portion of the channel layer. In a top view, the first opening exposes the two first edges of the mesa structure without exposing the two second edges of the mesa structure. A metal layer is formed in the first opening and the second openings thereby forming a contact structure.

  • Publication number: 20240149494
    Abstract: A method for silicon carbide ingot peeling includes the steps of: placing the silicon carbide ingot between first and second suckers; having a pressing head disposed on a top surface of the first sucker to apply mechanical oscillatory energy to both the silicon carbide ingot and the second sucker through the first sucker; and, having an elastic element disposed under the second sucker to absorb part of the mechanical oscillatory energy to transmit longitudinal waves thereof to a modified layer of the silicon carbide ingot for propagating individually intermittent invisible cracks at the modified layer to break silicon carbide chains at different levels. Till the cracks connect together for forming a continuous crack across the silicon carbide ingot, a top portion of the silicon carbide ingot is then separable therefrom to form a wafer. In addition, an apparatus for silicon carbide ingot peeling is also provided.

  • Publication number: 20240154015
    Abstract: A method includes forming a first fin and a second fin protruding from a frontside of a substrate, forming a gate stack over the first and second fins, forming a dielectric feature dividing the gate stack into a first segment engaging the first fin and a second segment engaging the second fin, and growing a first epitaxial feature on the first fin and a second epitaxial feature on the second fin. The dielectric feature is disposed between the first and second epitaxial features. The method also includes performing an etching process on a backside of the substrate to form a backside trench, and forming a backside via in the backside trench. The backside trench exposes the dielectric feature and the first and second epitaxial features. The backside via straddles the dielectric feature and is in electrical connection with the first and second epitaxial features.

  • Publication number: 20240148933
    Abstract: The present invention is directed to compressed hemostatic tablets or forms comprising a fibrous non-woven oxidized cellulose (OC or ORC) multilayer material compressed into a form stable tablet, further comprising calcium salt, with the tablets rapidly expandable on contact with blood or blood plasma. The compressed forms may further comprise a multi-arm PEG-SG and are dimensionally, preferably with regard to length and width, stable for at least 48 hours after compression. In some embodiments, the compressed forms will expand upon contact with blood from 1.5 to 5 times of tablet length in 5 seconds; from 2 to 6 times of tablet length in 20 seconds; and from 3 to 6 times of tablet length in 5 minutes. The compressed forms are effective in hemostasis in heparinized blood.
