Latest Patents

One of his latest patents is titled "Methods for controlling dopant concentration and activation in semiconductor structures." This invention provides innovative methods for fabricating semiconductor structures and devices, particularly ultra-shallow doped semiconductor structures that exhibit low electrical resistance. The methods utilize modifications of the composition of semiconductor surfaces to fabricate a doped semiconductor structure with a selected dopant concentration depth profile. This advancement is crucial for creating useful junctions and other device components in microelectronic and nanoelectronic devices, such as transistors in high-density integrated circuits. Additionally, the surface modification allows for better control of the concentration and depth profile of defects in undersaturated semiconductor materials.

Another significant patent is the "Fast model predictive ellipsoid control process." This model predictive control process approximates a constraint set as an ellipsoid to directly address actuator limitations. It provides a robust controller structure while reducing computational demands. The process involves approximating a bounded polytope defining the constraint set as an ellipsoid through off-line computation. The ellipsoid is then scaled on-line via bisection to determine the optimal fit for the polytope, calculating a set of control moves for manipulating device actuators.
