  • Patent number: 7986041
    Abstract: As etch-stop films or Cu-diffusion barrier films used in insulation films constituting conductor layers of a stacked structure, films having smaller dielectric constant than silicon nitride films are used, and an insulation film at a lower-layer part of the stacked structure is made to have smaller dielectric constant than that at an upper-layer part thereof, and further this insulation film is a silicon oxide (SiO) film and has, in the interior thereof, nano-pores of from 0.05 nm or more to 4 nm or less in diameter as chief construction. This makes it possible to dramatically reduce effective dielectric constant while keeping the mechanical strength of the conductor layers themselves, and can materialize a highly reliable and high-performance semiconductor device having mitigated the wiring delay of signals which pass through wirings.

  • Patent number: 7482650
    Abstract: For improving the filling properties between vertical MISFETs constituting a SRAM memory cell, the vertical MISFETs are formed over horizontal drive MISFETs and transfer MISFETs, and they are disposed with a narrow pitch in the Y direction and a wide pitch in the X direction. After a first insulating film (O3-TEOS) having good coverage is disposed over a columnar laminates having a lower semiconductor layer, an intermediate semiconductor layer, an upper semiconductor layer and a silicon nitride film and a gate electrode formed over the side walls of the laminates via a gate insulating film to completely fill a narrow pitch space, a second insulating film (HDP silicon oxide film) is deposited over the first insulating film, resulting in an improvement in the filling properties, even in a narrow pitch portion, between vertical MISFETs having a high aspect ratio.

  • Patent number: 6967407
    Abstract: A semiconductor device capable of high speed operation with a substantially small interlayer capacitance is produced by steps of using an insulating film comprising an organic insulating film and an insulating film composed of an organometallic polymer material as an interlayer insulating film formed by coating, patterning the insulating film in a semi-thermosetting state, etching the organic insulating film as the lower layer by means of the organometallic polymer as a mask, using a plasma gas containing oxygen as the main component, and then conducting ultimate baking treatment of these insulating films.

  • Patent number: 6731399
    Abstract: A color image processing system is provided which receives binary image data from an external device, which generates the binary image data, so as to form color images. This system has a first mode in which a receiving side receives the same binary image signal color plane by color plane so that a color process is performed. It also has a second mode in which a printer receives binary image data in a plane sequence, which data indicates color planes corresponding to the types of coloring materials used for a printing operation of the printer, and then, the printer performs binary printing in accordance with the binary image data. An indicating device for indicating the first or second mode selects the first or second mode with respect to the binary image data from the external unit.
