Our office uses the Schick 33 sensor, a start of the art chip with a suggested retail price north of $8,000.  Any CMOS chip as big as size 2 x-ray film is actually quite expensive...a $500 nVidia 1080 board has 340 square mm in its main chip. A $400 Intel i7 has 49 mm^2. The cost of producing a silicon chip is basically how many you can cram on a single silicon wafer.  In other words, they are priced by surface area, just like the carpet in your home.
