Abstract

An optoelectronic tweezer device includes a transparent substrate, a semiconductor layer, a first electrode and a dielectric layer. The semiconductor layer is located above the transparent substrate and includes a first doping region, a second doping region and a transition region, wherein the transition region is located between the first doping region and the second doping region. The first electrode is located on the first doping region and is electrically connected to the first doping region. The dielectric layer is located above the semiconductor layer and has a first through hole overlapping the first electrode.
