How CCD sensors are made

Did you ever wonder how CCD sensors are made? A CCD, or Charge-coupled device, is the chip that converts light into electricity and is how a digital camera can record images. The Science Channel has a 'How Its Made' segment in their program where they answer this question.

Nowadays most DSLRs use CMOS sensors instead of CCD. These CMOS sensors are cheaper to manufactor. In their earlier days CMOS sensors produced more image noise that CCD sensors. Today the difference in quality is minimal. If you're wondering about the differences between these sensor types, check out this How Stuff Works article.
