  • Methods of stacking semiconductor dies
    Patent number: 10497691
    Abstract: A method of stacking semiconductor dies includes attaching a lower semiconductor die to a base substrate with an adhesive layer and attaching an upper semiconductor die to the lower semiconductor die with another adhesive layer. A thermo-compression bonding technique is applied to the upper semiconductor die to cure the adhesive layers and to bond the upper semiconductor die to the lower semiconductor die.
    Type: Grant
