You can still keep the physical sensor size the same but use a smaller process. Of course, if you can use 450mm+ wafer sizes at 25nm vs. 300mm wafers at <=10nm

- sudosysgen 6y agoBut you still need to have the same wafer area if you are keeping the same sensor size. So you can't have 300mm wafers at <10nm, you still need 864+mm (for a FF sensor).
- aesthesia 6y agoThat’s the sensor area. GP is referring to the diameter of the wafer, on which you can fit many 36x24mm full frame sensors. Larger wafers improve throughput and thus reduce cost per sensor.
- sudosysgen 6y agoOh yep, misread it.
