STRUCTURE AND METHOD TO USE ACTIVE SURFACE OF A SENSOR

Abstract: disclosed is an apparatus and method of forming, including a supporting structure, a sensor on the supporting structure, a pair of columns on the supporting structure at opposite sides of the sensor, the pair of columns having a column height relative to a top surface of the supporting structure, the column height being higher than a height of the active surface of the sensor relative to the top surface of the supporting structure, and a lidding layer on the pair of columns and over the active surface, the lidding layer being supported at opposite ends by the pair of columns. the active surface of the sensor, the lidding layer and the pair of columns form an opening above at least more than about half of the active surface of the sensor, and the supporting structure, the sensor, the lidding layer and the pair of columns together form a flow cell.
