摘要: A method of manufacturing a mask ROM. A sacrificial silicon oxide layer is formed on the active region upon the substrate. Patterning the sacrificial silicon oxide layer in order to form a plurality of parallel openings, thereby exposing a portion of the active region. A polysilicon layer is formed on the openings and openings are formed thereon. An ion implantation process is performed on the polysilicon layer. Using a thermal flow process, the ions within the polysilicon layer are driven through the openings into the lower portion of the substrate, thereby forming an ion doping region. The polysilicon layer is etchbacked until the sacrificial silicon oxide layer is exposed. The sacrificial silicon oxide layer is removed.

摘要: A method of fabricating CMOS image sensor. On a substrate, an isolation layer is formed to partition the substrate into a photodiode sensing region and a transistor element region. Next, on the transistor element region, a gate electrode structure is formed and then, a source/drain region is formed at the transistor element region of the two lateral sides of the gate electrode structure. At the same time, a doping region is formed on the photodiode sensing region. After that, a self-aligned barrier layer is formed on the photodiode sensing region and a protective layer is formed on the substrate. Then, a dielectric layer and a metallic conductive wire are successively formed on the protective layer. Again, a protective layer is formed on the dielectric layer and the metallic conductive wire, wherein the numbers of the dielectric layers and the metallic conductive wire depend on the fabrication process. A protective layer is formed between every dielectric layer.
