Latest Patents
One of his latest patents is titled "Method of forming a SIMOX structure." This invention focuses on creating a SIMOX structure with a reduced number of defects through a two-step anneal process. The first step involves a conventional anneal that densifies the buried oxide layer, making it less reactive with hydrogen. The second step, an H₂/Si anneal, forms a quasi-equilibrium at the surface of the semiconductor layer, minimizing silicon surface etching and allowing for the dissolution of oxide precipitates. Another significant patent is "Non-silicon and silicon bonded structure and method of manufacture." This invention describes a method for bonding a non-silicon substrate to a silicon substrate using a stress-relief layer. This layer mitigates the stress caused by differing thermal expansion coefficients between the two materials, ensuring a more stable bond.
