Latest Patents

One of Luc Ouellet's latest patents is focused on a method for forming a flip-chip-on-board assembly. This innovative technique involves joining an integrated circuit (IC) chip, which has a polyimide passivation layer, to a chip carrier using a series of solder bumps. These bumps create electrical connections between the contact pads on the IC chip and the corresponding contacts on the chip carrier. A unique aspect of this method is the creation of a space between the surface of the passivation layer and the chip carrier. Ouellet applies a plasma treatment to chemically modify the surfaces of both the chip carrier and the IC chip's passivation layer without roughening the passivation layer's surface. The plasma used can be either an O plasma or a microwave-generated Ar and N O plasma. An underfill encapsulant material is then applied to fill the space, enhancing adhesion between the encapsulant and both the IC chip and the chip carrier. This method can be performed either after joining the components or simultaneously, showcasing Ouellet's innovative approach to improving electronic assembly processes.
