  • Patent number: 12114503
    Abstract: Some embodiments relate to an integrated chip that includes a first source/drain region and a second source/drain region disposed in a substrate. A plane that is substantially perpendicular to an upper surface of the substrate traverses the first source/drain region and the second source/drain region. Agate electrode extends over a channel region in the substrate between the first source/drain region and the second source/drain region. The gate electrode is separated from the channel region by way of a charge trapping dielectric structure. The charge trapping dielectric structure includes a tunnel dielectric layer, a charge trapping dielectric layer over the tunnel dielectric layer, and a blocking dielectric layer over the charge trapping dielectric layer. The channel region has a channel width measured perpendicularly to the plane, and the tunnel dielectric layer has different thicknesses at different respective points along the channel width.

  • Publication number: 20240146028
    Abstract: A method for manufacturing a distributed Bragg reflector is provided. The distributed Bragg reflector is applied to a 1550 nm vertical-cavity surface-emitting laser, which structurally includes a top distributed Bragg reflector, a bottom distributed Bragg reflector, and a vertical cavity (including a P-type and an N-type electrode) and a multiple quantum well light-emitting layer that are positioned therebetween. An optical multilayer film of the distributed Bragg reflector is formed by sputtering, and includes silicon layers and silicon dioxide layers alternately stacked to each other. The silicon dioxide layers are produced by a process of nano-sputtering and micro-plasma oxidation. A reflectance of the bottom distributed Bragg reflector at 1,550 nm is greater than 99.9%, and a reflectance of the top distributed Bragg reflector at 1,550 nm is controlled to be between 95% and 99%, so that basic physical/optical requirements for forming a resonant laser can be improved.
