It's all about yield, dark current, and defectivity tolerance. The big boys in the industry (OV/TSMC, SONY, Samsung, ...) know the tricks. And the answer is technically, Yes (it is already in production).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-18035067182016217242011-07-06T01:59:00.930+03:002011-07-06T01:59:00.930+03:00The answer is:

It still looks possible to me, albeit a little awkward.Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-89130924670697124762011-07-05T22:43:46.258+03:002011-07-05T22:43:46.258+03:00So the answer is YES or NO please ???So the answer is YES or NO please ???Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-76909797631909707972011-07-05T20:30:40.780+03:002011-07-05T20:30:40.780+03:00Or on backside thinned CCDsOr on backside thinned CCDsDave Gilblomhttp://www.alt-vision.comnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-28477522197442487152011-07-05T20:28:37.195+03:002011-07-05T20:28:37.195+03:00Generally not.

In order to provide a good AR coating, you have to have access to the silicon surface so something with an index of refraction higher than that of SiO2 can be deposited as the first layer. You can see examples of these coatings on scientific silicon photodiodes.Dave Gilblomhttp://www.alt-vision.comnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-29669759019148546572011-07-04T22:32:07.873+03:002011-07-04T22:32:07.873+03:00A stupide question:
