Latest Patents

Seiichi Bamba holds a patent for a method of fabricating MMIC semiconductor integrated circuits. This method involves forming an active device, such as a HEMT (High Electron Mobility Transistor), on a GaAs (Gallium Arsenide) substrate. The characteristics of this active device are measured, and a circuit pattern for a passive circuit device, including a serial microstrip line, is simulated based on these measurements. The resulting circuit pattern is then directly drawn on a substrate to create the passive circuit device. This process ensures that the passive circuit device is tailored to the characteristics of the active device for each chip, effectively canceling variations in the active device's characteristics and resulting in an MMIC with superior matching.
