  • Publication number: 20250062778
    Abstract: A processor decompresses a compressed data vector into an original data vector. The processor includes an execution circuit, which receives a decompress instruction that includes two input operands and an output operand. The input operands indicate an address of the compressed data vector in a memory, and the output operand indicates the vector register for storing the original data vector after decompression. The execution circuit executes the decompress instruction to decompress the compressed data vector. When executing the decompress instruction, the execution circuit performs the following operations: read a mask value from the mask register, the mask value being a binary sequence indicating zero positions in the original data vector; generate a selection signal based on the mask value; and generate the original data vector by applying the selection signal to a selection switch that receives the compressed data vector as input.

  • Patent number: 12229487
    Abstract: A method includes cropping a plurality of images from a layout of an integrated circuit, generating a first plurality of hash values, each from one of the plurality of images, loading a second plurality of hash values stored in a hotspot library, and comparing each of the first plurality of hash values with each of the second plurality of hash values. The step of comparing includes calculating a similarity value between the each of the first plurality of hash values and the each of the second plurality of hash values. The method further includes comparing the similarity value with a pre-determined threshold similarity value, and in response to a result that the similarity value is greater than the pre-determined threshold similarity value, recording a position of a corresponding image that has the result. The position is the position of the corresponding image in the layout.

  • Publication number: 20250053103
    Abstract: Some implementations described herein include operating components in a lithography system at variable speeds to reduce, minimize, and/or prevent particle generation due to rubbing of or collision between contact parts of the components. In some implementations, a component in a path of transfer of a semiconductor substrate in the lithography system is operated at a relatively high movement speed through a first portion of an actuation operation, and is operated at a reduced movement speed (e.g., a movement speed that is less than the high movement speed) through a second portion of the actuation operation in which contact parts of the component are to interact. The reduced movement speed reduces the likelihood of particle generation and/or release from the contact parts when the contact parts interact, while the high movement speed provides a high semiconductor substrate throughput in the lithography system.

  • Publication number: 20250054786
    Abstract: A die bonding tool includes a bond head having a moveable component. The moveable component may be moveable between an extended position in which a lower surface of the moveable component protrudes below a lower surface of the bond head and a retracted position in which the lower surface of the moveable component does not protrude below the lower surface of the bond head. The moveable component may be used to control a shape of a semiconductor die secured to the lower surface of the bond head during a process of bonding the semiconductor die to a substrate. Accordingly, void areas and other bonding defects may be avoided and the bond formed between the semiconductor die and the target substrate may be improved.
