Latest Patents

One of his latest patents is titled "Micro-electromechanical switch fabricated by simultaneous formation of a resistor and bottom electrode." This invention provides a method for integrating a bias resistor in circuit with a bottom electrode of a micro-electromechanical switch on a silicon substrate. The process involves sequentially depositing layers of resistor material, hard mask material, and metal material on a silicon substrate to form a stack. The bottom electrode and resistor lengths are then patterned and etched, followed by a second etching process to remove the hard mask and metal materials. Finally, the structure is encapsulated with a layer of dielectric, which is patterned and etched to correspond to the defined bottom electrode and resistor.

Another notable patent is the "Multi-output amplifier with isolation between outputs." This apparatus comprises a first circuit and a second circuit, where the first circuit generates an intermediate signal in response to an input signal. The second circuit generates multiple output signals that are amplified versions of the input signal and are isolated from each other.
