Patent ID: 8703543

Claim:
A method to vertically bond a chip to a substrate, the method comprising: forming a metal bar having a linear aspect on the substrate; forming a first solder paste layer over the metal bar to form a solder bar; forming a plurality of metal pads on the substrate; and forming a second solder paste layer over the plurality of metal pads to form a plurality of solder pads on the substrate, each of the plurality of solder pads being offset from a long edge of the solder bar by an offset-spacing, wherein the chip to be vertically bonded to the substrate has a vertical-chip thickness fractionally less than the offset-spacing, wherein the chip to be vertically bonded fits between the plurality of solder pads and the solder bar, wherein the solder bar enables alignment of the chip to be vertically bonded; bonding the chip to the substrate, wherein the chip is vertically oriented between the plurality of metal pads and the solder bar, wherein the solder bar contacts and holds the chip in a vertical orientation before solder reflow and the solder bar does not touch the chip after the solder reflow.
