RFsemi Develops MEMS Microphone... "Mass Production Begins"

[Asia Economy Reporter Hyunseok Yoo] RF Semi, a semiconductor device specialist company, announced on the 24th that it has completed the development of a high-performance MEMS microphone and has entered full-scale production.

MEMS (Micro-Electro-Mechanical Systems) is a technology that integrates ultra-fine mechanical parts and electronic circuits of micrometer (㎛) size on a silicon substrate by applying semiconductor manufacturing processes.

Microphones produced using this process allow automatic mounting compared to conventional Electret Condenser Microphones (ECM), making them suitable for mobile devices. The MEMS microphone developed this time applies the production technology and quality control know-how accumulated over 20 years in the ECM microphone business by RF Semi, securing 30% price competitiveness compared to existing products, the company explained.

RF Semi currently produces 2 million units per month at its Jeonju factory, which has a 6-inch fab and assembly line, and plans to expand production scale according to sales growth.

The company reduced facility investment costs by remodeling its existing ECM chip production line and expects to rapidly expand the market by utilizing the ECM chip sales network, which holds over 60% of the global market share.

Jinhyo Lee, CEO of RF Semi, stated, "RF Semi, ranked number one in the global ECM chip market share, has expanded its lineup with the MEMS microphone, securing a new growth engine," and added, "We are also developing MEMS microphone chips with built-in MLCC functionality."
