Title: Wei-Cheng Tzeng: Innovator in Complementary Field Effect Transistor Technology
Introduction
Wei-Cheng Tzeng is an inventor based in Hsinchu, Taiwan. He is known for his work in the field of complementary field-effect transistors (CFETs). Although he currently holds no granted patents, his innovative ideas are reflected in his latest patent applications.
Latest Patent Applications
Wei-Cheng Tzeng has submitted several notable patent applications. One of his latest applications is for a device that includes a complementary transistor. This device features a first transistor with a first and second source/drain region, and a second transistor stacked on the first. The third source/drain region of the second transistor overlaps with the first source/drain region, while the fourth source/drain region overlaps with the second source/drain region. The device also includes source/drain contacts, a gate isolation structure, and an interconnect structure that electrically couples the source/drain contacts.
Another significant application is for an integrated circuit (IC) device that incorporates a CFET device. This IC device features conductors on either side of the CFET device, with a local interconnect that electrically couples the two conductors. The gate of the CFET device is arranged in a plane that intersects the local interconnect, ensuring electrical isolation.
Conclusion
Wei-Cheng Tzeng is an innovative inventor making strides in the field of complementary field-effect transistors. His latest patent applications showcase his commitment to advancing technology in this area.
