MEMS Drive CEO Interview

Elektor publishes an interview with MEMS Drive CEO Colin Kwan. Few interesting quotes:

"Currently, OIS technology is mainly implemented in high-end phones, which is less than 20% of the cellphone market. Yet OIS technology is gradually penetrating the middle and low-end cellphone markets as people have higher requirements for photo taking.

OIS actuator technology in mobile phones has been mainly dominated by a few voice coil motor (VCM) suppliers. However, none has been able to provide all round shake compensation. No matter it is VCM shifting lens or tilting lens, the roll axis is not able to be compensated through lens movement. MEMS Drive saw this as an opportunity and came out with a MEMS OIS actuator, the world’s first five-axis (i.e., pitch, yaw, roll, x/y translation) optical image stabilization in mobile phones.

MEMS OIS is a MEMS actuator that sits underneath the image sensor. By moving the image sensor in the x/y plane in a very fast and precise way, MEMS OIS counteracts undesired vibrations that cause image blur while taking a photo. It makes fundamental changes on a camera module’s mechanical systems and breaks through the limitations of conventional VCM OIS, which works through lens movement. MEMS OIS has sub-micron accuracy and in-position compensation within 10 ms. It is ultra-low power (e.g., 50-plus times lower than traditional VCM OIS), which is extremely beneficial for mobile phones and other portable devices. MEMS OIS also has competitive advantages when applied in dual/triple cameras since it causes no magnetic interference."

Film-Based Light Sensing Review

University of Toronto repo publishes a Nature paper from January 2017 "Solution-processed semiconductors for next-generation photodetectors" by F. Pelayo García de Arquer, Ardalan Armin, Paul Meredith, and Edward H. Sargent. " Efficient light detection is central to modern science and technology. Current photodetectors mainly use photodiodes based on crystalline inorganic elemental semiconductors, such as silicon, or compounds such as III–V semiconductors. Photodetectors made of solution-processed semiconductors — which include organic materials, metal-halide perovskites and quantum dots — have recently emerged as candidates for next-generation light sensing. They combine ease of processing, tailorable optoelectronic properties, facile integration with complementary metal–oxide–semiconductors, compatibility with flexible substrates and good performance. Here, we review the recent advances and the open challenges in the field of solution-processed photodetectors, examin...

Synaptics Under-Display Fingerprint Scanner Reverse Engineering

SystemPlus Consulting publishes a reverse engineering report of Synaptics’ under-display fingerprint scanner found inside the VIVO X21 UD Smartphone: " This scanner uses optical fingerprint technology that allows integration under the display. With a stainless steel support and two flexible printed circuit layers, the Synaptics fingerprint sensor’s dimensions are 6.46 mm x 9.09 mm, with an application specific integrated circuit (ASIC) driver in the flex module. This image sensor is also assembled with a glass substrate where filters are deposited. The sensor has a resolution of 30,625 pixels, with a pixel density of 777ppi. The module’s light source is providing by the OLED display glasses. The fingerprint module uses a collimator layer corresponding to the layers directly deposited on the die sensor and composed of organic, metallic and silicon layers. This only allows light rays reflected at normal incidence to the collimator filter layer to pass through and reach the optical ...

Review of Ion Implantation Technology for Image Sensors

MDPI Sensor publishes " A Review of Ion Implantation Technology for Image Sensors " by Nobukazu Teranishi, Genshu Fuse, and Michiro Sugitani from Shizuoka and Hyogo Universities and Sumitomo. " Image sensors are so sensitive to metal contamination that they can detect even one metal atom per pixel. To reduce the metal contamination, the plasma shower using RF (radio frequency) plasma generation is a representative example. The electrostatic angular energy filter after the mass analyzing magnet is a highly effective method to remove energetic metal contamination. The protection layer on the silicon is needed to protect the silicon wafer against the physisorbed metals. The thickness of the protection layer should be determined by considering the knock-on depth. The damage by ion implantation also causes blemishes. It becomes larger in the following conditions if the other conditions are the same; a. higher energy; b. larger dose; c. smaller beam size (higher beam current d...
