Title: The Innovations of Wood-Hi Cheng: A Pioneer in MEMS and LED Technologies
Introduction
Wood-Hi Cheng, an accomplished inventor based in Kaohsiung, Taiwan, has made significant contributions to the fields of micro-electro-mechanical systems (MEMS) and light-emitting diodes (LEDs). With a remarkable portfolio that includes nine patents, Cheng's work has been instrumental in advancing technologies that enhance audio and visual applications.
Latest Patents
Among his most notable inventions, Cheng has developed a MEMS microphone module and its innovative manufacturing process. This invention optimizes the thickness of a transparent temporary cover plate used in conventional plastic package structures. The process employs ultraviolet (UV) irradiation to minimize adherence on the cover plate and the back surface of the MEMS acoustic wave sensing chip, thereby creating an effective back-volume essential for the functionality of the MEMS microphone. This technique ensures that the back-volume is precisely aligned with the dimensions of the entire MEMS microphone chip.
Additionally, Cheng's LED package module structure represents another cutting-edge innovation in the industry. This design integrates a LED module within a reflection cup and features a light-transmitting color conversion member mounted on the annular surface of the cup. The stationary package secures the color conversion member without the need for adhesive agents, streamlining the packaging process and significantly reducing costs.
