Title: Innovations of Dong Chun Park
Introduction
Dong Chun Park is a notable inventor based in Incheon, South Korea. He has made significant contributions to the field of micro-electromechanical systems (MEMS), particularly in the development of microphones. With a total of 3 patents to his name, Park continues to push the boundaries of technology.
Latest Patents
One of his latest patents is a MEMS microphone and method of manufacturing the same. This innovative microphone design includes a substrate that presents a vibration area, a supporting area surrounding the vibration area, and a peripheral area surrounding the supporting area. The substrate defines a cavity formed in the vibration area, with a lower back plate disposed over the substrate to cover the cavity and featuring a plurality of lower acoustic holes. The diaphragm, which is spaced apart from the lower back plate, generates displacement in response to applied acoustic pressure. An upper back plate is also included, which has a plurality of upper acoustic holes. An intermediate anchor supports the diaphragm, providing the necessary elasticity.
Another patent by Park involves a MEMS microphone that also includes a substrate with a cavity and a back plate covering the cavity. This design features a diaphragm that senses acoustic pressure to create displacement, along with a first insulation layer that supports the diaphragm. This innovation simplifies the manufacturing process by omitting the need for an anchor, thereby shortening process time.
