Publication number: 20230317663Abstract: A semiconductor device has a semiconductor die. A first dielectric layer is formed over the semiconductor die. A second dielectric layer is formed over the first dielectric layer. A trench is formed in the second dielectric layer. A via opening is formed to expose a contact pad of the semiconductor die within the trench. A seed layer is formed over the second dielectric layer. The seed layer extends into the trench and via opening. A conductive material is deposited into the via opening and trench. The conductive material is overburdened from the trench. The seed layer around the conductive material is etched in a first etching step. The conductive material is etched in a second etching step.Type: ApplicationFiled: April 4, 2022Publication date: October 5, 2023Applicant: STATS ChipPAC Pte.

Patent number: 11767843Abstract: A scroll compressor may include an oil supply passage formed in a main frame. A first end of the oil supply passage may be open toward an orbiting space of the main frame and a second end may be open toward an Oldham ring. With this configuration, even if refrigerant suctioned through a refrigerant suction pipe sweeps away oil, which lubricates a sliding surface between a key and a key groove adjacent to the refrigerant suction pipe while passing through between the key and the key groove, oil may be quickly and smoothly supplied to the sliding surface. This may prevent wear between the key and the key groove so as to enhance efficiency of the compressor.Type: GrantFiled: June 17, 2022Date of Patent: September 26, 2023Assignee: LG ELECTRONICS INC.Inventors: Changeol Jo, Suchul Kim, Junghwan Jang

Publication number: 20230259033Abstract: A semiconductor manufacturing device has an outer cup and inner cup with a wafer mount disposed within the outer cup. A semiconductor wafer is disposed on the wafer mount. A dispenser dispenses a photoresist material onto a surface of the semiconductor wafer. A controller controls the dispenser to apply in a single application, the photoresist material to the surface of the semiconductor wafer while rotating at a first speed to form a thickness of the photoresist material up to 12.0 micrometers, or in the range of 3.0 to 12.0 micrometers. The first speed ranges from 400 to 700 RPM. The controller controls the dispenser to discontinue application of the photoresist material while rotating the semiconductor wafer at the first speed. The photoresist material dries while rotating the semiconductor wafer. The controller controls the dispenser to apply a coating to the semiconductor wafer prior to applying the photoresist material.Type: ApplicationFiled: February 11, 2022Publication date: August 17, 2023Applicant: STATS ChipPAC Pte.

Publication number: 20220365436Abstract: A semiconductor manufacturing device has an outer cup and inner cup with a wafer suction mount disposed within the outer cup. A photoresist material is applied to a first surface of a semiconductor wafer disposed on the wafer suction mount while rotating at a first speed. A gas port is disposed on the inner cup for dispensing a gas oriented toward a bottom side of the semiconductor wafer. The gas port purges a second surface of the semiconductor wafer with a gas to remove contamination. The second surface of the semiconductor wafer is rinsed while purging with the gas. The gas can be a stable or inert gas, such as nitrogen. The contamination is removed from the second surface of the semiconductor wafer through an outlet between the inner cup and outer cup. The semiconductor wafer rotates at a second greater speed after discontinuing purge with the gas.Type: ApplicationFiled: May 13, 2021Publication date: November 17, 2022Applicant: STATS ChipPAC Pte.
