  • Publication number: 20250308951
    Abstract: Aspects of the present disclosure provide an apparatus that heats a semiconductor structure while holding the semiconductor structure. For example, the apparatus can include a semiconductor structure holding device that is configured to hold the semiconductor structure. The apparatus can also include a light projection device that is configured to generate a certain pattern of light. The light projection device can be integrated with the semiconductor structure holding device such that when the semiconductor structure holding device is holding the semiconductor structure, the certain pattern of light generated by the light projection device is projected onto the semiconductor structure holding device and a corresponding certain pattern of heat is generated and transferred through the semiconductor structure holding device and applied to the semiconductor structure, in order to correct the shape and size of the semiconductor structure.

  • Patent number: 12381118
    Abstract: Aspects of the present disclosure provide a bonding device for bonding two wafers. For example, the bonding device can include a first bonding chuck and a second bonding chuck. The first bonding chuck can have a first bonding head for a first wafer to be mounted thereon. The second bonding chuck can have a plurality of second bonding heads for a second wafer to be mounted thereon. The second bonding heads can be controlled individually to apply local pressures onto the second wafer to move the second wafer toward the first wafer to bond the second wafer to the first wafer, the local pressures corresponding to bow measurement of the first wafer and the second wafer.

  • Publication number: 20250226265
    Abstract: Aspects of the present disclosure provide a method for correcting an overlay error by shifting lithographic patterns to be formed on a wafer according to a bow measurement of the wafer. For example, the method can include receiving a first location at which one or more first semiconductor elements are to be formed on a first wafer, measuring the first wafer to identify a first bow measurement of the first wafer, calculating a second location that is shifted from the first location based on the first bow measurement, and forming the first semiconductor elements on the first wafer at the second location.

  • Patent number: 12099299
    Abstract: A method for patterning a substrate in which a patterned photoresist structure can be formed on the substrate, the patterned photoresist structure having a sidewall. A conformal layer of spacer material can be deposited on the sidewall. The patterned photoresist structure can then be removed from the substrate, leaving behind the spacer material. Then, the substrate can be directionally etched using the sidewall spacer as an etch mask to form the substrate having a target critical dimension.

  • Patent number: 6872301
    Abstract: A high shear rotating disc filter having a hollow interior and constructed of a porous material such as sintered metal or ceramic with finely structured openings. The disc is mounted and secured onto a hollow shaft. The hollow shaft is connected to a vacuum source, external to the filter, that allows for the passage of the filtrate to a receiver. There are elongated slots in the wall of the shaft which provide the passage of filtrate from the disc. The shaft provides rotational force for the discs.
