Latest Patents

Junwei Hu's latest patents include a temperature compensation circuit and a phased array apparatus. The temperature compensation circuit is designed to be applied to a signal processing path. It consists of a temperature detection circuit, a temperature conversion circuit, and a passive variable attenuator. The passive variable attenuator is connected in series within the signal processing path. The temperature detection circuit generates a temperature signal and a reference signal, which are then output to the temperature conversion circuit. This circuit generates a control signal based on the temperature signal and the reference signal. The passive variable attenuator adjusts the attenuation value of the processed signal under the control of the control signal.

His second patent involves a method of forming a perforated opening in the bottom substrate of a flip-chip pop assembly to reduce the bleeding of underfill material. This semiconductor device features a flip-chip semiconductor die mounted to a first substrate using multiple first bumps. An opening is formed in the first substrate at the center of the flip-chip semiconductor die placement. A second substrate holds multiple semiconductor dies that are electrically connected with bond wires. An encapsulant covers the semiconductor dies and the second substrate. The second substrate is then mounted to the first substrate with several second bumps. Underfill material is dispensed through the opening in the first substrate, and the dispensing is stopped as it approaches the perimeter of the flip-chip semiconductor die to minimize bleeding.
