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
