Sony and Apple Think Alike

Sony patent application US20150129943 "Solid-state imaging device, method of manufacturing a solid-state imaging device, and electronic apparatus" by Nanako Kato and Toshifumi Wakano, presents a stacked global shutter pixel where the storage diode is shielded from the backside illumination:

Sony stacked GS pixel

Sony's idea looks quite similar to the one presented by Apple in US20150035028 application:

IC Insights: Sharp CIS Sales Surge

IC Insights posts its updated list of top 20 semiconductor companies. This time, Sharp has entered the list as #19. IC Insight writes: "Although Sharp as a whole is having a difficult time, its semiconductor group, which represents only about 14% of the company’s corporate sales, posted a whopping 62% growth rate (an 88% increase in yen), the best 1Q15 sales increase of any top-20 semiconductor supplier. This sales surge was almost entirely due to the company’s success in the CMOS image sensor market."

Update: Sharp's medium term management plan dated by May 14, 2015, reveals quite ambitious plans over the next few years:

The company notes: "Sharp has the leading share in the industry for smartphone camera devices, but since specific customers weight a large proportion of our business, we will aggressively work to expand our sales to new customers, and target 3 times the net sales of Fiscal 2014 by Fiscal 2017."

IHS on Omnivision Acquisition

IHS publishes its analysts opinions on implications of Omnivision acquisition by Chinese investment companies. Few quotes:

"One of the greatest concerns regarding China-backed Hua Capital Management Co. Ltd.’s proposed acquisition of OmniVision Technologies Inc. is that it would give OmniVision an unfair advantage over other image-sensor vendors, with Chinese firms favoring Omnivision products over others. But, according to IHS, this scenario is unlikely to play out.

...the vast majority of OmniVision’s current business is already in China. O’Rourke says about 75% of OmniVision’s 2014 revenues came from China-based companies.

“In this situation, there’s not a great deal of room left for OmniVision’s growth in China," O’Rourke says. "Thus, the question of Chinese companies or the Chinese government favoring it may be irrelevant.”

...the funding groups bought OmniVision mainly for a “capital operation” and will have the company listed in the China stock market to gain a sizable return.

Wang says he believes OmniVision will invest heavily in the near term—including spending more on R&D to develop high-end products—in order to help the company catch up with image sensor heavyweights Sony and Samsung.

Sony Presents New Generation Global Shutter Sensors with 3.45um Pixel

Sony announces 5.07MP 2/3-inch IMX250LLR/LQR and 3.2MP 1/1.8-inch IMX252LLR/LQR sensors featuring a new generation global shutter pixel. Sony says that the new 3.45um pixels are industry's smallest global shutter pixels for industrial applications. The pixels feature improved sensitivity, 1.1 times over the company's previous generation of 5.86 ┬Ám pixels. In addition, EXview HAD CCD technology is said to increases sensitivity in NIR (see the bigger 800 x 670 pictures on Sony site):

The sensors are fairly fast, slightly faster than the previous generation IMX174:

Sony also publishes a Youtube video showing a global shutter advantage:

Pelican Gets New COO

PRNewswire: Pelican Imaging announces that Mark Fulks has joined the company as COO to lead engineering and product development for Pelican's depth-sensing array solutions. Prior to joining Pelican, Fulks led Nokia's product and engineering teams that created Nokia's augmented reality product, Nokia City Lens, and led the core development teams at Sun Microsystems for Java ME (J2ME). He began his career as an embedded systems software engineer, after earning his Bachelor's degree in Computer Science with a minor in Physics from Sonoma State University. Fulks holds several patents related to augmented reality interfaces and displays.

"Pelican Imaging is uniquely positioned to achieve success across multiple growth markets. I'm very excited to join as COO, leading the engineering and product development teams to bring this disruptive 3D imaging technology to consumers," said Fulks.

Omnivision News: MIPI over Fiber, 3DInCites Award Nomination

PRNewswire: OmniVision and Silicon Line GmbH announced a collaboration to bring high-speed image and video data transfer technology to applications that are noise-sensitive and that require longer, thinner and lighter cables. This collaboration will focus on 1080p30 video transfer over 2-lane 1Gbps MIPI for OmniVision's OV5693 sensor, as well as other MIPI D-PHY 1.1, 1.2, 2.0 and MIPI C-PHY-based imaging solutions.

"We believe that Silicon Line's approach to high-speed data transfer, and the inherent benefits that its optical link technology brings to our mutual target markets, can help overcome many technical challenges faced by product engineers today," said Tehzeeb Gunja, senior marketing and business development manager at OmniVision. "The ability to affordably and power-efficiently transfer large amounts of uncompressed video data over long distances carries a tremendous potential for positive impact on a number of application areas."

"As OmniVision extends its portfolio with higher resolution and higher frame rate image sensors, the required data rate for transporting the image increases dramatically," said Ian Jackson, senior manager sales and marketing at Silicon Line. "A single optical fiber can transport up to 25 Gbps of data. This has obvious benefits in terms of size and weight reductions, enabling smaller and lighter industrial designs for space-constrained applications like tablets and notebooks. Another benefit of optical fiber is zero susceptibility to electromagnetic interference, which enables a noise free picture. Lastly, optical technology can transport high-speed image data over many meters whereas a traditional electrical connection is limited to 10 or 20 cm, making optical technology well-suited for applications such as automotive, medical and security imaging systems." (Actually, a single optical fiber transmits 100Gbps since 2012 in commercial products, and, this year, 200Gbps would be probably commercialized - ISW.)

3DInCites nominates OmniVision’s 23.8MP OV23850 PureCel stacked sensor for 3D Excellence Award. OV23850 "gives 3D manufacturing visibility across numerous application areas, including automotive, medical, mobile devices, and wearables."
