Looking at the sensor under microscope the amount of photons received is determined more by the area of the pixel than the size of the features under that area:<p><a href="http:&#x2F;&#x2F;petapixel.com&#x2F;2013&#x2F;02&#x2F;12&#x2F;what-a-dslrs-cmos-sensor-looks-like-under-a-microscope&#x2F;" rel="nofollow">http:&#x2F;&#x2F;petapixel.com&#x2F;2013&#x2F;02&#x2F;12&#x2F;what-a-dslrs-cmos-sensor-loo...</a><p>I&#x27;d still like to get a link in support of the claim of significant benefit of lithography process improvement to the sensor sensitivity, unless it&#x27;s about the smallest sensors (as in mobile phones or smaller) and very high pixel count.
