Invisage publishes an impressively big list of newspaper articles covering the opening of its QFAB3 in Taiwan last month. The article that has attracted my attention is a Chinese site 52RD interview with Jess Lee, Invisage CEO. Few quotes, in Bing translation:
"Compared to CMOS, quantum films have a very big advantage, is very thin. Jess said, quantum well thin film sensor modules can do 4mm, and minimum can only do 4.8mm CMOS sensor module, though only the 0.8mm gap, but used on cell phone cameras and wearable devices, will be a big change, maybe your next-generation iPhone camera will not be highlighted."
"The Taiwan new factories are small, but the plant can support 10% market. Production processes are TSMC's wafers first, then we will spread the quantum film, then to partners to test, then made modules. This process and the traditional CMOS is the same, just adding the cover of quantum film, a step, so quantum thin film sensor camera performance can be increased 5 times."
"At present, we only produce a small number of wafer and will ramp up in the second half of this year. ...our first samples had been provided to a number of important customers, they have done tests and gave very positive feedback, later this year we will have more samples available to more customers. Over time, our formal product launches will be held in Shanghai, and after product formal release, we will provide samples for Mainland, 7 August should be, we can look forward to you."
"InVisage will focus on cell phone cameras, this is a very large market and opportunities. Smartphone carrying quantum thin-film technologies are expected to be listed in 1 year."
"...we have no competitors or partners before, but last year we held out olive branches of the two companies, Sony is one of their quantum is very interested in thin film technology."
"As shown in the image above, Orange represents QuantumFilm absorption capacity, gray are Silicon absorbs light, you can see the gap between the two great. The biggest advantage is that absorption capacity can increase the dynamic range of the camera, dynamic range represents the phone can take a much brighter white and dark black, best embodies quality and filmed under strong light at night. Low light performance is the greatest weakness of the CMOS sensor and mobile phones cannot be one of the main reasons that night."
The interview concludes with a comparison picture with the regular CMOS sensors on the left and Invisage QuantumFilm device on the right. The first row compares full well, I guess, (4000e- vs 12,000e-), the second row is a camera module z-height (5mm vs 4mm), the third row shows the absense of rolling shutter distortions in QF sensors.
