Latest Patents

One of his latest patents is titled "Dislocation free local oxidation of silicon with suppression of narrow space field oxide thinning effect." This innovative design of an oxidation mask improves control of the birds beak and tailors the field oxide isolation profile in sub half-micron integrated circuit technology. The mask utilizes a thin silicon nitride foot to allow nominal expansion of the oxide during early oxidation stages, facilitating in-situ stress relief and smoothing of the oxide profile. Additionally, a cantilevered portion of a thicker silicon nitride layer suppresses upward movement during later oxidation stages, significantly reducing shear stresses responsible for dislocation generation.

Another notable patent is the "Method and mask structure for self-aligning ion implanting to form various device structures." This method enables the creation of self-aligned sub-micrometer bipolar transistors and FETs on a substrate for BiFET and BiCMOS circuits. The novel LOCOS structure serves as a self-aligned implant mask, allowing for efficient formation of the emitter, base, and collector of bipolar transistors without the need for separate photoresist masks. This method minimizes the thermal budget and enhances the performance of the devices.
