An integrated semiconductor device for manipulating and processing bio-entity samples is disclosed. The device includes a microfluidic channel that is coupled to fluidic control circuitry, a photosensor array coupled to sensor control circuitry, an optical component aligned with the photosensor array to manipulate a light signal before the light signal reaches the photosensor array, and a microfluidic grid coupled to the microfluidic channel and providing for transport of bio-entity sample droplets by electrowetting. The device further includes logic circuitry coupled to the fluidic control circuitry and the sensor control circuitry, with the fluidic control circuitry, the sensor control circuitry, and the logic circuitry being formed on a first substrate.
