SeekingAlpha: Tower Q2 2020 earnings call has few updates on the foundry's imaging business:
"Moving to our Sensor Business unit, we forecast single-digit year-over-year growth in spite of several segments being strongly adversely impacted by COVID-19. For example, dental x-ray sensors where we have major market share. The impact is mainly seen in the form of customer requests to push out orders, dental clinics were closed for a long period and are still not back to full speed hence customers are very inventory cautious. Industrial sensors namely manufacturing line inspections is also down as a function of reduced new manufacturing line build out. Due to our very strong CIS platform and compatibility, our fingerprint sensors namely the under OLED 101 sensor and the under LCD lens type modules, we were developed and qualified in very short times. We target our first volume production revenue in the fourth quarter wrapping throughout 2021.
Our time-of-flight program is moving along very well. We are prototyping the first sensor to our lead customer this quarter and plans for after production in the first half of next year. This would be our first product moving to mass production utilizing our stacked wafer BSI pixel level bonding platform.
And as stated, for us, one of the beauties of that market is that we were able to very, very quickly develop and qualify flows because of a very, very strong and diverse CIS core that we have throughout the company. So CMOS image sensor throughout the company, and take advantage of a market need. As far as the time-of- flight, there's a variety of applications are going out for time of flight. It's predominantly at 300 millimeter. And it's focused with backside illumination and stack wafers. And that is also more than one customer with blue chip customers that are signed up on long-term agreements. Of course, we have to perform, but that is a very, very substantial market for us.
But we have seen a very, very big reduction in the forecast of the image sensors for dental X-ray."
