Latest Patents
One of his latest patents is titled "Method and apparatus for populating an adhesive sheet with particles." This invention outlines a method for assembling electronic devices by moving particles on an adhesive sheet that has multiple adhesive areas. The process involves loading particles onto the adhesive sheet and transferring kinetic energy from a mechanical device to facilitate the movement of these particles. The adhesive sheet may consist of an adhesive coating laminated to a film, and the particles can be made from various materials, including minerals, solder, or polymers.
Another significant patent by Lessard is "Fixture and a method for plating contact bumps for integrated circuits." This patent describes a plating fixture designed to hold a silicon wafer containing integrated circuits in a metal plating bath. The wafer is coated with photoresist to achieve the desired bump height, and the locations for the bumps are patterned using standard photolithographic techniques. This innovative approach prevents yield loss by ensuring that air is not trapped in the photoresist pattern, which can lead to under plating or uneven plating of the bumps.
