With a total of 10 patents to his name, Knollenberg has demonstrated a remarkable capacity for innovation, leading to advancements in the manufacturing processes of electronic components.

Latest Patents

Among his most recent inventions is a patent for "Fabrication for Electroplating Thick Metal Pads." This method involves creating a seed region on a substrate, then forming a ground plane, which is kept electrically isolated from the seed region. The process of electroplating follows, enabling the formation of a structure that includes a substrate, a passivation layer, and at least one electroplated metal region that maintains contiguous contact with the passivation layer. This innovation culminates in a device featuring bond pads and solder beads that connect components to these pads efficiently.

Another significant patent is his work on "Laser-Induced Flaw Formation in Nitride Semiconductors." This method enables the selective decomposition of regions within a thin film structure to create flaws in a predetermined pattern. The induced flaws concentrate stress in the film layer during a stress-inducing operation, ultimately allowing for controlled fracturing of the material in accordance with the designed pattern.
