  • Publication number: 20250046633
    Abstract: A semiconductor processing system is provided. The semiconductor processing system includes a first chamber arranged to perform a first semiconductor process; a second chamber arranged to perform a second semiconductor process; a cooling chamber having a pedestal; and a plurality of non-contact temperature sensors mounted in the cooling chamber, and arranged to measure a temperature of a wafer disposed on the pedestal. In one aspect, the first chamber is arranged to transfer the wafer to the cooling chamber upon completion of the first semiconductor process in the first chamber. In another aspect, the cooling chamber is arranged to measure the temperature of the wafer in the cooling chamber and arranged to transfer the wafer to the second chamber when the temperature of wafer is at a target temperature, or pause processing of the wafer when the temperature of the wafer is not at the target temperature.

  • Patent number: 11557470
    Abstract: A sputtering target assembly, sputtering apparatus, and method, the target assembly including a backing plate having an aperture formed therein; and a target bonded to a front surface of the backing plate. The aperture is disposed on the backing plate such that a first end of the aperture is sealed by a portion of the target that is predicted by a sputtering target erosion profile to have the highest etching rate during a corresponding sputtering process.

  • Patent number: 9960244
    Abstract: A field effect transistor includes a substrate, an epitaxial layer, a remnant-oxide layer, an electrode, a surrounding-oxide layer, a surrounding-nitride layer, a gate oxide layer, a gate, a P-body region, a source region, an interlayer dielectric and a source electrode. The epitaxial layer on the substrate has a trench having a sidewall and a bottom. The electrode inside the trench is coated subsequently by the surrounding-oxide layer, the surrounding-nitride layer and the remnant-oxide layer. The gate formed on the gate oxide layer is separated from the electrode sequentially by the gate oxide layer, the surrounding-nitride layer and the surrounding-oxide layer. The P-body region and the source region, formed at the epitaxial layer, are separated from the gate by the gate oxide layer. The interlayer dielectric covers the source region and the gate. The source electrode covers the P-body region and the interlayer dielectric, and contacts the source region.

  • Patent number: 9905690
    Abstract: A field effect transistor is manufactured by firstly forming an epitaxial layer on a substrate. Then, a trench having an oxide layer is formed on the epitaxial layer. The oxide layer has a first electrode portion having a first width and a first height and a second electrode portion having a second width and a second height. A gate oxide layer covering the oxide layer and the second electrode portion has a gate portion having a third width. The epitaxial layer has a body region and a source region, where these two regions are adjacent to the gate portion and covered by an interlayer dielectric. A source electrode covering the body region and the interlayer dielectric contacts the source region. The first height is no less than the second height, the first width is smaller than the second width, and the second width is smaller than the third width.

  • Patent number: 9741825
    Abstract: A method for manufacturing a field effect transistor having a widened trench forms sequentially an epitaxial layer, a trench, an oxidation layer, a trench-oxidation layer, a polysilicon layer, a residual oxidation layer, an electrode portion, a lower trench, a widened trench, a gate portion, a body region, a source region, an interlayer dielectric layer and a source electrode. The trench is formed at the epitaxial layer. The oxidation layer, the trench-oxidation layer and a polysilicon layer are then formed. The residual oxidation layer and the electrode portion are formed in the trench by etching the polysilicon layer and the trench-oxidation layer. The lower trench is formed by etching the epitaxial layer. The widened trench is formed by widening a portion of the trench away from a trench bottom so as to have the electrode portion and the residual oxidation layer disposed at the lower trench.
