- Sony will evolve, World of Digital Imaging

※ point press release August 20, 2012 1
Sony Corporation (hereafter Sony) CMOS image sensor "Exmor RS" newly developed recruitment and ※ 1, the world's first structure "stacked" own commercialized (Exmore ares es), shipments sequentially from October I will start. We will expand the three models imaging module that adopts towards such as smartphones and tablets to achieve and compact, high-performance high image quality further, the image of each sensor CMOS image sensor "Exmor RS" stacked 3 and the model, .
Sony has been actively promoting the future, the expansion of the product mix and technological development of CMOS image sensor "Exmor RS" stacked core technology to evolve products, digital imaging, spread the enjoyment of photography easier to use, which is a device Go.

Using the chip signal processing circuit is formed in place of the supporting substrate of the CMOS image sensor back-illuminated, superposed portions pixel pixel backside illumination type is formed thereon, "Exmor RS" is unique " It is a CMOS image sensor that employs a "stacked structure.

Three models of "Exmor RS" commercialized, raised the sensitivity without adding pixels (white) W to pixel (red / green / blue) RGB traditional detract from the quality signal processing technology and to its own devices this The capabilities and "RGBW Coding" You can shoot, set the exposure conditions of the two in the same screen at the time of shooting cleanly at night or a dark room, by appropriate signal processing to the image obtained there, it is a wide dynamic range to generate an image, the features can be vivid in color backlight "(High Dynamic Range) Movie HDR", "IMX134 of 8.08 million pixels" IMX135 "of 13.13 million effective pixel 1/3.06 type, valid for 1/4 is ISX014 "" of 8.08 million effective pixels 1/4 type with built-in camera and signal processing, ".Adoption of "stacked structure", in addition to the high image quality and high performance These were both downsizing.
In addition, each image sensor, auto focus to commercialize imaging module "IU135F3-Z" "IU134F9-Z", "IUS014F-Z" a compact unit with a lens with auto-focus mechanism. Imaging module of these three models, high resolution has been achieved by adopting a newly designed lens, which is optimized for the industry's smallest unit pixel ※ 1 1.12μm. "IU135F3-Z" is the auto focus imaging module that employs a high-resolution lens bright F2.2. "IU134F9-Z" is thin and miniaturization has been achieved (W: 4.2mm ※ 4 8.5x D:: 8.5x H). "IUS014F-Z" is an all-in-one imaging module type with a camera signal processing functions on the image sensor, with built-in auto-focus and image quality adjustment.

Future, actively promote the development of CMOS image sensor "Exmor RS" stacked, towards such as smart spaces embedded imaging module is limited by the increase in the size of the display screen, Sony is taking advantage of the features of the structure "stacked" aim was, the commercialization of imaging modules to achieve high performance and miniaturization, higher image quality, while expanding the product mix, we will continue to respond more to the needs of our customers.

By the mobile device market demand, such as smartphones and tablets is growing rapidly, to strengthen the ※ 2 supply system of CMOS image sensors stacked to achieve both miniaturization and high functionality, Sony is leading the CMOS image sensor consolidate the position, I will continue to lead the industry in the future.

※ In the Nagasaki Technology Center of Sony Semiconductor Co., Ltd. 2, are (dated June 22) announced the implementation of capital investment that aims to increase the production capacity of the CMOS image sensor stacked.
