Abstract

The described embodiments may provide a method of fabricating a chemical detection device. The method may comprise forming a microwell above a CMOS device. The microwell may comprise a bottom surface and sidewalls. The method may further comprise applying a first chemical to be selectively attached to the bottom surface of the microwell, forming a metal oxide layer on the sidewalls of the microwell, and applying a second chemical to be selectively attached to the sidewalls of the microwell. The second chemical may lack an affinity to the first chemical.
