Latest Patents

One of his latest patents is for an "Acoustic isolator having a high impedance layer of hafnium oxide." This invention supports a thin film acoustic resonator that comprises a layer of piezoelectric material with top and bottom electrical contacts. The resonant acoustic isolator consists of at least one pair of layers of materials with differing acoustic impedances. The materials are deposited in alternating layers of high and low impedance, with each layer having a thickness of 1/4 acoustic wavelength at the resonant frequency. Silicon dioxide (SiO₂) is preferred for the low impedance material due to its ubiquity in the semiconductor industry and low intrinsic acoustic loss. Hafnium oxide (HfO₂) is chosen for the high acoustic impedance material, as it can be deposited to form a hard, dense dielectric. This method allows for low-cost production using electron beam deposition techniques.

Another significant patent is the "Method of fabricating a diamond moth-eye surface." This process combines a high-temperature resist with microlithographic patterning to produce materials like diamond films that require a high-temperature deposition environment. A high-temperature silicon nitride resist is utilized for microlithographic patterning of a silicon substrate, which enhances diamond film adhesion and provides a uniform distribution of nucleation sites. The process can also create surface relief features and microstructures of fine-grained polycrystalline diamond, which possess desirable characteristics such as hardness, wear resistance, and low friction.
