Semiconductor-based chemical detection device

A semiconductor device, comprising:

• a plurality of first output circuits at a first side of a chemical detection circuit;
• a plurality of second output circuits at a second side of the chemical detection circuit, the second side being opposite to the first side;
• and
• a plurality of tiles of pixels each placed between a respective first output circuit and a respective second output circuit, each tile comprising:
• four quadrants of pixels, each quadrant comprising:
• a plurality of first columns;
• and
• a plurality of second columns interleaved with the plurality of first columns, each first column and second column having a plurality of pixels formed in rows,
• wherein each first column in first and second quadrants is coupled to the respective first output circuit, and each second column in first and second quadrants is coupled to the respective second output circuit,
• wherein each first column in third and fourth quadrants is coupled to the respective second output circuit, and each second column in third and fourth quadrants is coupled to the respective first output circuit.
