Fingerprint identification chip when the phone is becoming "standard", the fingerprint sensor frequently out of stock news, and several domestic fingerprint identification chip manufacturers quickly jumped at the chance. CITE's booth at the interview, SMIC "carry" the two very unique clients, Lo Kei and Mindray micro, they each with its unique fingerprint identification products to attract the audience's attention. Also in SMIC foundry, the two companies fingerprint sensor used is not the same principle / based foundry: Using optical structures, and Mindray uses a capacitive micro structure Lo Kei technology; basket One of the core components of the sensor technology Kei readout chip (ROIC) is used in SMIC 0.18um mixed signal 3.3V technology, microelectronics AFS120 Mindray products using SMIC Semiconductor Manufacturing Co., mature technology 0.35umCMOS .With the rise of Chinese chip company, SMIC from solid growth in domestic orders, according to the company's executive vice president Li Zhi to "Electronic Engineering Times" reporter revealed that the current local customers SMIC contributed more than half of international revenues. It is worth mentioning that these two fingerprint sensor has a unique value not only in performance, but also in the patent application, but also to avoid the Apple patent barriers to success.
