A semiconductor device comprising a laminate structure of a first portion (103) principally composed of a component same as the principal component of the semiconductor layers (101), and a second portion consisting of a metal (104). PMOS device (P1) and NMOS device (N1) are formed on a semiconductor substrate (101) to constitute a CMOS circuit. On an oxide film (102) is formed a laminate electrode wiring structure consisting of a single semiconductor layer (103) and a metal layer (104), serving as gate electrodes and wirings for both devices. Said semiconductor layer (103) is doped in p-type in a portion 103A at the side of the PMOS device, and in n-type in a portion 103B at the side of the NNOS device on the entire area of the semiconductor layer (103) (e.g. polysilicon), there is deposited selectively a metal layer 104 composed of Al or principally of Al, or of another metal such Cu, Mo or W.
摘要:
Disclosed is a method of manufacturing semiconductor devices in which a desired pattern having an area size larger than the field size that can be obtained in one exposure process step of an exposure device is formed. The manufacturing method includes the steps of dividing the desired pattern into a plurality of portions, and conducting exposure on the dividing patterns in a joined fashion.

In a photoelectric conversion device comprising a photoelectric-conversion section and a peripheral circuit section where signals sent from the photoelectric-conversion section are processed, the both sections being provided on the same semiconductor substrate, a semiconductor compound layer of a high-melting point metal is provided on the source and drain and a gate electrode of an MOS transistor that forms the peripheral circuit section, and the top surface of a semiconductor diffusion layer that serves as a light-receiving part of the photoelectric conversion section is in contact with an insulating layer.
摘要:
A pattern forming method comprises subjecting a surface of a semiconductor substrate to surface treatment for imparting hydrogen atoms, irradiating a desired region of said surface with an energy ray, selectively forming a metal film on a non-irradiated region other than the desired region, and etching said semiconductor substrate using said metal film as a mask.
