  • Publication number: 20230411342
    Abstract: In one example, a system comprises a laser assisted bonding (LAB) tool. The LAB tool comprises a stage block and a first lateral laser source facing the stage block from a lateral side of the stage block. The stage block is configured to support a substrate and a first electronic component coupled with the substrate, and the first electronic component comprises a first interconnect. The first lateral laser source is configured to emit a first lateral laser beam laterally toward the stage block to induce a first heat on the first interconnect to bond the first interconnect with the substrate. Other examples and related methods are also disclosed herein.

  • Patent number: 11749637
    Abstract: In one example, a method to manufacture a semiconductor device comprises providing an electronic component over a substrate, wherein an interconnect of the electronic component contacts a conductive structure of the substrate, providing the substrate over a laser assisted bonding (LAB) tool, wherein the LAB tool comprises a stage block with a window, and heating the interconnect with a laser beam through the window until the interconnect is bonded with the conductive structure. Other examples and related methods are also disclosed herein.

  • Publication number: 20210398936
    Abstract: In one example, a system can comprise a laser assisted bonding (LAB) tool comprising a stage block and a laser source facing the stage block. The stage block can be configured to support a first substrate and a first electronic component coupled with the first substrate, the first electronic component comprising a first interconnect. The laser source can be configured to emit a first laser towards the stage block to induce a first heat on the first interconnect to bond the first interconnect with the first substrate. Other examples and related methods are also disclosed herein.
