  • Publication number: 20240145316
    Abstract: A bonding tool includes a bonding monitoring system. The bonding monitoring system may include one or more sensors that are configured to generate bonding wave propagation data associated with a bonding operation. As a bond between a top semiconductor substrate and a bottom semiconductor substrate propagates from respective centers to respective perimeters of the top semiconductor substrate and the bottom semiconductor substrate, the one or more sensors of the bonding monitoring system generates the bonding wave propagation data. A controller that communicates with the one or more sensors receives the bonding wave propagation data from the one or more sensors. The controller may monitor the bonding wave propagation based on the bonding wave propagation data and/or may determine various performance parameters of the bonding operation, such as a bonding wave propagation rate and/or a bonding wave propagation uniformity, among other examples.

  • Publication number: 20240107780
    Abstract: A system on chip (SoC) die package is attached to a redistribution structure of a semiconductor device package such that a top surface of the SoC die package is above a top surface of an adjacent memory die package. This may be achieved through the use of various attachment structures that increase the height of the SoC die package. After encapsulating the memory die package and the SoC die package in an encapsulation layer, the encapsulation layer is grinded down. The top surface of the SoC die package being above the top surface of the adjacent memory die package results in the top surface of the SoC die package being exposed through the encapsulation layer after the grinding operation. This enables heat to be dissipated through the top surface of the SoC die package.
