Abstract:
An electronic assembly (150) includes a workpiece (110), a through substrate via (TSV) die (120) including a substrate (105) and a plurality of TSVs (115), a topside (121) and a bottomside (122) having TSV connectors (113) thereon. The TSV die is attached to the workpiece with its topside on the workpiece. A heat spreader (130) having an inner open window (131) is on the bottomside of the TSV die. Bonding features (161) are coupled to the TSV connectors or include the TSV connectors themselves. The bonding features protrude from the inner open window to a height above a height of the top (132) of the heat spreader that allows a top die to be bonded thereto.
Abstract:
A method (100) of through-substrate via (TSV) die assembly includes positioning (101) a plurality of TSV die with their topside facing down onto a curable bonding adhesive layer on a carrier. The plurality of TSV die include contactable TSVs that include or are coupled to bondable bottomside features protruding from its bottomside. The curable bonding adhesive layer is cured (102) after the positioning. A plurality of second IC die each having a plurality of second bonding features are bonded (103) onto the plurality of TSV die to form a plurality of stacked die assemblies on the carrier. Debonding (104) after the bonding separates the carrier from the plurality of stacked die assemblies. The plurality of stacked die assemblies are then singulated (105) to form a plurality of singulated stacked die assemblies.

Abstract:
A semiconductor device (10) includes a first memory die (12) having a first memory type, a second memory die (14) having a second memory type different from the first memory type, and a logic die (16) such as a microprocessor. The first memory die (12) can be electrically connected to the logic die (16) using a first type of electrical connection preferred for the first memory type. The second memory die (14) can be electrically connected to the logic die using a second type of electrical connection different from the first type of electrical connection which is preferred for the second memory type. Other devices can include dies of the same type, or two or more dies of a first type and two or more dies of a second type different from the first type.
Abstract:
A method (100) for assembling die packages includes attaching contacts (101) on a first side of a plurality of first die to substrate pads on a top surface of a composite carrier. The composite carrier includes a package substrate including at least one embedded metal layer having its bottom surface secured to a semiconductor wafer. The composite carrier minimizes effects of the coefficient of thermal expansion (CTE) mismatch between the die and the package substrate during assembly reduces warpage of the die. After the attaching, the semiconductor wafer is removed (103) from the package substrate. Electrically conductive connectors are attached (104) to the bottom surface of the package substrate, and the package substrate is sawed (105) to form a plurality of singulated die packages.
