Abstract:
Some embodiments of the invention include a connecting structure between a support and at least one die attached to the support. The die includes a number of die bond pads on a surface of the die. The connecting structure includes a plurality of via and groove combinations. Conductive material is formed in the via and groove combinations to provide connection between the die bond pads and bond pads on the support. Other embodiments are described and claimed.
Abstract:
A method and apparatus for soldering a chip (1a) to a substrate (3). A chip carrier (8) is provided between a flash lamp (5) and the substrate (3). The chip (1a) is attached to the chip carrier (8) on a side of the chip carrier (8) facing the substrate (3). A solder material (2) is disposed between the chip (1a) and the substrate (3). The flash lamp (5) generates a light pulse (6) for heating the chip (1a). The heating of the chip (1a) causes the chip (1a) to be released from the chip carrier (8) towards the substrate (3). The solder material (2) is at least partially melted by contact with the heated chip (1a) for attaching the chip (1a) to the substrate (3).
Abstract:
A method of forming a microelectronic package, and a package formed according to the method. The method includes: providing a microelectronic substrate including bonding pads and solder bumps on respective ones of the bonding pads; providing a microelectronic die including bumping sites thereon; providing solder caps on the bumping sites; positioning the die onto the substrate to form a die-substrate combination, positioning including placing respective ones of the solder caps on the die in registration with corresponding ones of the solder bumps on the substrate; and bonding the die to the substrate by subjecting the die-substrate combination to reflow to form solder joints from the solder caps and solder bumps.
