Abstract:
A hybrid diode comprising:a first semiconductor layer; a gate structure, formed on the first semiconductor layer with a second semiconductor layer stacked on an isolating layer; a first N-type diffusion region, formed on the first semiconductor layer adjacent to the gate structure; a second N-type diffusion region, formed on the second semiconductor layer, wherein the first and the second N-type diffusion regions belong to a first common region implanted during N-type implantation; a first P-type diffusion region, formed on the first semiconductor layer adjacent to the gate structure; a second P-type diffusion region, formed on the second semiconductor layer, wherein the first and the second P-type diffusion regions belong to a second common region implanted during P-type implantation; and an inter-connection; wherein the first N-type diffusion region and the first P-type diffusion region are respectively the cathode and anode of a first diode; the second N-type diffusion region and the second P-type diffusion region are respectively the cathode and anode of a second diode; and the inter-connection connects the first and second diodes in parallel or in series to form the hybrid diode.
