									          CMOS
Complementary Metal Oxide Semiconductor




            Scott Moody
          CMOS Beginnings


1998 CMOS Emerged as alternative image capture
      technology
2000 Foveon Inc developed X3 technology
2002 First Widespread use of CMOS in high end
      digital cameras
           Foveon Inc Contribution
Before X3 developed sensor technology was
.35 to .50 micron technology

Company’s were trying to develop .25 micron technology

Foveon developed a .18 micron technology

Smaller diodes mean higher resolution and quality in the
same space
From Film to CMOS
X3 Foveon
               Benefits of CMOS


CMOS manufacturing process very similar to that of traditional
     computer processors
     CCD very specialist and costly to produce
CMOS capable of doing multitasking
     CCD just registers light
CMOS very low power consumption
     CCD high energy process
