Introduction

Chih-Lung Cheng is an inventive mind based in Tainan, Taiwan. He has made significant strides in the fields of semiconductor technology and health applications. Although he currently holds no granted patents, his innovative ideas are reflected in his latest patent applications.

Latest Patent Applications

One of his notable applications is for a "GUARD RING WITH DEEP TRENCH ISOLATION STRUCTURE." This process involves forming a first deep trench isolation (DTI) structure in a pixel region of a semiconductor substrate, which is also utilized to create a second DTI structure in a guard ring area. This structure effectively isolates the pixel region from a peripheral region. The guard ring area may incorporate a PNP guard ring structure, with trenches in each of the inner, middle, and outer rings. The conductive cores of these rings can be biased to different voltages, allowing the second DTI structure to function as a guard ring without the PNP structure.

Another significant application is the "PHYSICAL HEALTH CAP APPLICATION SYSTEM." This system features an electrode cap designed to fit any person's head, along with a main unit that includes a DC-stimulator and a positive and negative DC current generator. This setup is electrically connected to the electrode cap, enabling it to discharge direct electrical currents into specific regions of the cerebral cortex. This innovative approach aims to help relieve pain effectively.
