  • Method for manufacturing semiconductor package substrate
    Patent number: 10840161
    Abstract: A method of manufacturing a semiconductor package substrate includes forming a trench in one surface of a base substrate formed of a conductive material, performing a first filling operation of filling the trench with resin, performing a first curing operation of semi-curing the resin filled in the first filling operation, performing a second filling operation of additionally filling resin on a semi-cured resin, performing a second curing operation of fully curing the resin, removing the resin exposed from the trench, and etching an opposite surface of the base substrate to expose at least part of the resin filling the trench.
    Type: Grant
