| 摘要 |
A method of manufacturing a PIN (positive-intrinsic-negative) diode structure includes depositing an insulation or dielectric layer over the bottom PIN diode electrodes, prior to depositing the PIN semiconductor layers. The insulation layer results in a PIN diode structure with reduced leakage current, reduced RIE (reactive ion etching) chamber contamination, the reduction or elimination of post RIE processing, improved yields, and/or expands the potential materials that may be used for the bottom electrode. A corresponding PIN diode structure is also disclosed. The resulting PIN diode structures may be used in, for example, LCD (liquid crystal display) and solid state imager applications.
