Abstract
The structure of a semiconductor device with an array of bioFET sensors, a biometric fingerprint sensor, and a temperature sensor and a method of fabricating the semiconductor device are disclosed. A method for fabricating the semiconductor device includes forming a gate electrode on a first side of a semiconductor substrate, forming a channel region between source and drain regions within the semiconductor substrate, and forming a piezoelectric sensor region on a second side of the semiconductor substrate. The second side is substantially parallel and opposite to the first side. The method further includes forming a temperature sensing electrode on the second side during the forming of the piezoelectric sensor region, forming a sensing well on the channel region, and binding capture reagents on the sensing well.
