SF Current and RTN

Japanese Journal of Applied Physics publishes Tohoku University paper "Effect of drain current on appearance probability and amplitude of random telegraph noise in low-noise CMOS image sensors" by Shinya Ichino, Takezo Mawaki, Akinobu Teramoto, Rihito Kuroda, Hyeonwoo Park, Shunichi Wakashima, Tetsuya Goto, Tomoyuki Suwa, and Shigetoshi Sugawa. It turns out that lower SF current can reduce RTN, at least for 0.18um process used in the test chip:

ST Announces 4m Range ToF Sensor

The VL53L1X TOF sensor extends the detection range of ST's FlightSense technology to four meters, bringing high-accuracy, low-power distance measurement, and proximity detection to an even wider variety of applications. The fully integrated VL53L1X measures only 4.9mm x 2.5mm x 1.56mm, allowing use even where space is very limited. It is also pin-compatible with its predecessor, the VL53L0X, allowing easy upgrading of existing products. The compact package contains the laser driver and emitter as well as SPAD array light receiver that gives ST’s FlightSense sensors their ranging speed and reliability. Furthermore, the 940nm emitter, operating in the non-visible spectrum, eliminates distracting light emission and can be hidden behind a protective window without impairing measurement performance.

ST publishes quite a detailed datasheet with the performance data:

Rumor: Mantis Vision 3D Camera to Appear in Samsung Galaxy S10 Phone

Korean newspaper The Investor quotes local media reports that Mantis Vision and camera module maker Namuga are developing 3-D sensing camera for Samsung next-generation Galaxy S smartphones, tentatively called the Galaxy S10. Namuga is also providing 3-D sensing modules for Intel’s RealSense AR cameras.

TechInsights: Samsung Galaxy S9+ Cameras Cost 12.7% of BOM

TechInsights Samsung Galaxy S9+ cost table estimates cameras cost at $48 out of $379 total. The previous generation S8 camera was estimated at $25.50 or 7.8% of the total BOM.

TechInsights publishes a cost comparison of this year and last yera;s flagship phones. Galaxy S9+ appears to have the largest investment in camera and imaging hardware:

Samsung CIS Production Capacity to Beat Sony

ETNews reports that Samsung is to convert its 300mm DRAM 13 line in Hwasung to CMOS sensors production. Since last year, the company also working to convert its DRAM 11 line in Hwasung into an image sensor production (named as S4 line). Conversion of S4 line will be done by end of this year. Right after that, Samsung is going to convert its 300mm 13 line. The 13 line can produce about 100,000 DRAM wafers per month. Because image sensor has more manufacturing steps than DRAM, the production capacity is said to be reduced by about 50% after conversion.

At the end of last year, production capacity of image sensor from 300mm plant based on wafer input was about 45,000 units.” said ETNews source. “Because production capacities of image sensor that will be added from 11 line and 13 line will exceed 70,000 units per month, Samsung Electronics will have production capacity of 120,000 units of image sensor after these conversion processes are over.

Sony CIS capacity is about 100,000 wafers per month. Even with Sony capacity extension plans are accounted, Samsung should be able to match or exceed Sony production capacity.

While increasing production capacity of 300mm CIS lines for 13MP and larger sensors, Samsung is planning to slowly decrease output of 200mm line located in Giheung.

Samsung capacity expansion demonstrates its market confidence. Samsung believes that its image sensor capabilities approach that of Sony. The number of the company's outside CIS customers is over 10.
