Blue Filters in Short Supply

Korea IT News, Digitimes report that so called "blue filters" used in high-resolution BSI camera modules are in short supply. The "blue filters" are made of IR-absorbing material that can keep its IR stopping efficiency in wide acceptance angle typical for modern BSI sensors. Older FSI-based modules used multi-layer IR cut filters which are more sensitive to the angle. Korean makers OPTRONTEC, OPTRONTECH, Nanos and LMS have entered the market dominated by Japanese Asahi Glass and German Schott and drive the prices down.


Samsung Securities report gives more examples of BSI sensor artifacts when used with older IR cut filters:

Toshiba to Start Sampling 3D Stereo Module in January 2014

Business Wire: Toshiba starts sample shipments of the previously announced TCM9518MD stereo camera module for smartphones, tablets and other mobile devices, on January 31, 2014. The new product is said to be the industry's first dual camera module to incorporate twin 1/4-inch 5MP sensors, which simultaneously outputs recorded images and depth data.

The depth data is calculated by a dedicated image processing LSI which measures and appends the depth data to objects in the image. Used in combination with customers' applications, the module supports new photo functions, including focus and defocus, and even allows objects in photographs to be extracted and erased. The image processing LSI generates 13MP images by upscaling images taken by the twin 5MP cameras, realizing a lower module height than that of conventional 13MP camera modules.

It's Official: TowerJazz Acquires 51% of Panasonic's Image Sensor Fabs, Including 12-inch 65nm CIS Line

Business Wire, Reuters: TowerJazz and Panasonic sign a definitive agreement to create a joint venture (JV) to manufacture Panasonic’s products. Panasonic will transfer its semiconductor manufacturing process and capacity tools of 8-inch and 12-inch wafers at its Hokuriku factories (Uozu, Tonami and Arai) to the JV, committing to acquire its products from the JV for a period of at least five years, and will transfer to TowerJazz 51% of the shares of this JV.

The JV is expected to increase TowerJazz’s technology offerings, including Panasonic's High Definition FSI technology known for high QE and low dark current. High Definition FSI is said to enable the use of FSI even for small pixels. It consists of light separation walls combined with a light pipe structure that funnels the light into the individual pixels with minimal light loss. This technology provides a high QE, and wide acceptance angles that helps in preventing shading at the periphery and improves color separation leading to true and vivid colors.

The dark current performance CIS technology is said to be one of the best in the industry, not only in the average very low values of dark currents even at elevated temperatures, but also with extremely small tail of high dark current pixels, known as hot pixels. As a result, Panasonic technology allows excellent images at low light conditions with no hot pixels in the image. This technology is well suited for high end DSLR type cameras.

Russell Ellwanger, TowerJazz CEO, commented, "We are honored to place our name side by side with Panasonic Corporation to create an innovative joint venture that provides high capacity, highest quality, multiple world leading analog platforms and, as well, 300mm advanced technology nodes. This partnership brings together two leaders – Panasonic, an acknowledged analog components and systems leader, and TowerJazz, a recognized analog foundry leader - to create a company that will serve and grow the analog foundry space as no existing single foundry company can."

For its 51% equity holding in the JV, TowerJazz will issue to Panasonic ordinary shares in the value of approximately $8M, based on TowerJazz average shares value during March 2014. As a result of holding its ordinary shares, Panasonic will become a minority stakeholder in TowerJazz. The JV balance sheet assets will include, among others, the cap-ex tools of the three fabs, cash in the amount of approximately $40M to be invested by Panasonic and work in process (inventories) manufactured at Panasonic fabs before the closing date.

Following this transaction, TowerJazz will rationalize its Japanese business, which may include fab consolidations between TowerJazz's Nishiwaki facility and the JV's facilities, and to this end, TowerJazz is evaluating potential ventures for the Nishiwaki facility. the 8-inch Nishiwaki plant has been acquired from Micron in 2011. It's used to manufacture Aptina sensors in 90nm process. Recently, Tower started to offer a foundry CIS process at Nishiwaki fab too.


Update: Panasonic has published more details on the JV fabs:

Ziptronix Sells its Development Lab to Tezzaron

Marketwired: Ziptronix announces an agreement with Tezzaron Semiconductor and Novati Technologies, a wholly owned subsidiary of Tezzaron, to sell its 3D IC development lab to Tezzaron, to be operated by Novati. Due to widespread adoption of direct bonding in volume manufacturing, Ziptronix no longer has to dedicate its resources to supporting a lab for commercialization of its patented ZiBond and DBI technologies. The deal includes a strategic agreement with Tezzaron that provides Ziptronix's lab customers continued access to the facility.

Triange Business Journal adds that Novati takes over 11 Ziptronix employees. The six remaining Ziptronix staffers moved from the lab with the headquarters in Raleigh, NC. Ziptronix's work will still be conducted at the facility as part of the deal. The 11 employees will continue "to do what they always did, but they’re working for Novati."

"ZiBond has been in high-volume manufacturing for several years now and DBI is well on its way into production," said Dan Donabedian, CEO of Ziptronix. "Quite simply, as the market is now convinced of the value of our technology, our needs have shifted. As we look to accelerate 3D integration, our focus is increasingly on addressing the needs of the maturing and emerging markets that are adopting our technology via licensing."

Ziptronix's DBI (Direct Bond Interconnect) is said to achieve over 100,000,000 electrical connections per square centimeter; a significant increase over the ~100,000 connections per square centimeter density achieved with through-die vias used in other 3D interconnect approaches. DBI is said to be considered by several manufacturers of next generation image sensors to directly connect control electronics and memory to the pixel sensing layer. This can enable direct control of the individual pixel with extremely short connections.
