  • Patent number: 12291795
    Abstract: A susceptor assembly for supporting a crucible during a crystal growth process includes a susceptor base, a tubular sidewall connected to the susceptor base, and a removable sacrifice ring interposed between the susceptor base and the sidewall. Each of the susceptor base and the sidewall is formed of a carbon-containing material. The susceptor base has an annular wall and a shoulder extending radially outward from an outer surface of the annular wall. The sidewall has a first end that receives the annular wall to connect the sidewall to the susceptor base. The sacrifice ring has a first surface that faces the outer surface of the annular wall, a second surface that faces an interior surface of the sidewall, and a ledge extending outward from the second surface that engages the first end of the sidewall.

  • Publication number: 20250129512
    Abstract: Methods for determining suitability of Czochralski growth conditions to produce silicon substrates for epitaxy. The methods involve evaluating substrates sliced from ingots grown under different growth conditions (e.g., impurity profiles) by imaging the wafer by infrared depolarization. An infrared depolarization parameter is generated for each epitaxial wafer. The parameters may be compared to determine which growth conditions are well-suited to produce substrates for epitaxial and/or post-epi heat treatments.

  • Publication number: 20250120164
    Abstract: A multi-threshold voltage semiconductor device and a method for fabricating the device are disclosed, in which a first metal material layer is formed on exposed dielectric layer in a part of gate trenches, and an annealing process is then carried out to cause diffusion of metal ions from the first metal material layer into the corresponding portion(s) of the high-k dielectric layer. In this way, two different threshold voltages can be achieved simply with one photolithography process and one etching process. More different threshold voltages can be achieved by adding photolithography processes. As fewer photolithography and etching processes are involved, the multi-threshold voltage semiconductor device can be fabricated at lower cost and exhibits improved consistency.

  • Publication number: 20240094527
    Abstract: A defog lens for vehicles includes a lens barrel, a lens, and a hydrophilic layer. The lens barrel has an opening toward an object side. The lens is disposed in the lens barrel and is located at the opening. The hydrophilic layer covers a surface of the lens and includes silicone compounds. Water droplets condensed on the lens could form a sheet film sticking to the surface of the lens and hard to form spherical water droplets, thereby improving the problem that the field of view of the conventional lens is blocked by spherical water droplets, effectively improving the clarity of the image captured by the defog lens, and therefore the defog lens could be applied to various environments.
