Abstract:
1. A method of fabricating a sensor comprising a nanowire on a support substrate with a first semiconductor layer arranged on the support substrate comprising: forming a fin structure from the first semiconductor layer, the fin structure comprising at least two supporting portions and a fin portion arranged there between; oxidizing at least the fin portion of the fin structure thereby forming the nanowire being surrounded by a first layer of oxide; and forming a first conductive layer on a contact surface of the supporting portions; forming a first insulating layer above the first conductive layer and a portion of the fin structure; removing a part of the first insulating layer to form a part of a microfluidic channel to make accessible a contact surface of the first layer of oxide surrounding the nanowire; wherein the supporting portions and the first insulating layer form the microfluidic channel and the first conductive layer is isolated from the microfluidic channel by a portion of the first insulating layer.
