Samsung Join Hands With Fujifilm to Create ISOCELL PLUS Sensors

Korean Giant Samsung and imaging industry leader Fuji silently working together behind the curtain to create a completely new and more powerful ISOCELL sensor. The new ISOCELL PLUS sensor

.

Let me explain you what Fuji did inside ISOCELL sensor to make it ISOCELL PLUS, earlier every two-sub pixels of of ISOCELL sensor was separated by a metal grid. Now, the metal grid is replaced by Fuji new innovative material. (well they didn’t disclosed what the innovative material is).

Highlights of ISOCELL PLUS Sensors Press Release

  1. Today introduced its new ‘ISOCELL Plus’ technology
  2. Absorb and hold more light than the conventional backside-illuminated (BSI) image sensor
  3. Samsung replaced the metal barrier with an innovative new material developed by Fujifilm, minimizing optical loss and light reflection.
  4. The new ISOCELL Plus delivers higher color fidelity along with up to a 15-percent enhancement in light sensitivity
  5. The technology also enables image sensors to equip 0.8-micrometer (µm) and smaller-sized pixels without any loss in performance, making it an optimal solution for developing super-resolution cameras with over 20 megapixels
  6. The ISOCELL Plus will be showcased at the Mobile World Congress Shanghai, held from June 27 to 29.

With the help of new technology Samsung is not only able to create more better sensor, but they can also create higher resolution sensor without any loss in performance.

We also expect in near future both companies will work together for the betterment of Sensors as well imagine technology to bring new innovative products for for consumers.

Samsung ISOCELL is Better than Sony BSI

Finally Samsung developed new pixel technology called ISOCELL, with the help of ISOCELL Samsung able to increase the light sensitivity of the sensor.

ISOCELL-Image

Previous sensor technology developments focused on improving the light absorption of each pixel, and have progressed pixel technology from FSI (Front Side Illumination) to BSI (Back Side Illumination) which places photodiode at the top to maximize photoelectric efficiency. While being very effective at the time, this BSI technology also faced limitations in improving image quality as pixel sizes continued to decrease.

ISOCELL is the next generation of pixel technology, which is patent pending. ISOCELL technology forms a physical barrier between neighboring pixels – isolating the pixel. This isolation enables more photons to be collected from the micro-lens and absorbed into the correct pixel’s photodiode minimizing undesired electrical crosstalk between pixels and allowing expanded full well capacity (FWC).

Additionally, an imager designed with ISOCELL can feature a 20 percent wider chief ray angle (CRA), reducing the height of the camera module. This makes it suitable for slim and small form factor mobile devices with challenging low z-height requirements.

As the first Samsung image sensor to adopt this new technology, the S5K4H5YB 8Megapixel imager utilizes a 1.12um ISOCELL pixel and has a 1/4inch optical format. The S5K4H5YB is currently sampling to customers with mass production scheduled for Q4 2013.

According to market research firm Techno System Research, in 2014, approximately 66 percent of smartphones will feature image sensors with 8Mp or higher resolution.
