Latest Patents

One of Wing Yau's latest patents is a method of making wide tuning range and super low capacitance varactor diodes. This semiconductor device includes a semiconductor die, an N-doped region, an N-contact metal, a PN junction mesa, a P-contact metal, a first passivation layer, an anode feed metal, and a cathode feed metal. The semiconductor die may consist of multiple semiconductor layers on an insulating substrate. The N-doped region defines the active area of the device, while the N-contact metal is placed on a portion of the N-doped region. The PN junction mesa is located on another portion of the N-doped region and comprises a hyperabrupt N-doping layer and a P-doped layer. The P-contact metal is situated on the P-doped layer of the PN junction mesa. The first passivation layer covers the semiconductor layers and has openings for the N-contact and P-contact metals. The anode feed metal connects the P-contact metal to a bond pad, forming an arch that defines a space between the anode feed metal and the first passivation layer.

Another notable patent is the planar broadband FET balun. This invention features three active FET baluns that utilize resonant, reactive, and resistive/reactive compensation, making them suitable for monolithic implementation. The design includes a single balanced mixer configuration with a resistive/reactive active FET balun coupled with a pair of single-ended FET mixers in a push-pull configuration, also suitable for monolithic implementation.
