Title: David Gaines: Innovator in Semiconductor Technology
Introduction
David Gaines is a prominent inventor based in Livermore, CA (US). He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work focuses on improving the efficiency and effectiveness of semiconductor processes.
Latest Patents
One of his latest patents is titled "Dual-loop control for laser annealing of semiconductor wafers." This invention discloses systems and methods for performing semiconductor laser annealing using dual loop control. The first control loop operates at a first frequency, managing the output of the laser and controlling the 1/f laser noise. The second control loop, operating at a lower frequency, measures the thermal emission of the wafer over an area the size of one or more die. This approach averages out within-die emissivity variations when determining the measured annealing temperature. The measured temperature and an annealing temperature set point are used to generate the control signal for the second control loop.
Another notable patent is "Systems and methods for measuring high-intensity light beams." This invention outlines methods for measuring an intensity characteristic of a light beam. The methods involve directing the light beam into a prism assembly that includes a thin prism sandwiched by two transparent plates. A portion of the light beam is reflected by a total-internal-reflection surface to an integrating sphere, while the remaining portion is transmitted through the transparent plates to a beam dump. The method also includes detecting light captured by the integrating sphere and determining the intensity characteristic from the detected light.
