Latest Patents
One of his latest patents is for a semiconductor laser with low vertical far-field. This invention describes a planar, topology-free, semiconductor quantum-well laser. The quantum-well active layer is formed and patterned in a specified region, constrained on all sides by high bandgaps created through impurity-free diffusion techniques. After this process, an upper portion is epitaxially deposited to complete the structure. High-power, single fundamental mode laser operation is achieved by funneling current into the constrained quantum-well active region, utilizing high bandgap regions along with low index of refraction in surrounding areas. The design also allows for low beam divergence in the direction perpendicular to the semiconductor laser junction.
Another significant patent is for a ceramic probe card and method for reducing leakage current. This electrical probe card is designed for parametric testing of microelectronics with reduced leakage current. It features a hydrophobic layer of a self-curing silicone material that coats the entire exposed surface of the ceramic card between the exposed conductors. The hydrophobic layer is thin, measuring less than 1 micrometer, and does not interfere with subsequent soldering to the contacts on the card. This innovative method of application involves applying an excess of the hydrophobic silicone material in its uncured state, followed by vigorous wiping to thin the layer and clean the exposed conductors.
