    摘要: An improved manufacturing method for a semiconductor device, which can reduce process inductive fault such as oxidation inductive stacking fault (OSF) and contribute to the improvement of the electric characteristics of the semiconductor device, is disclosed. A thermal oxide film is formed on a semiconductor substrate, then a nitride film is formed and a medium temperature heat treatment is provided to the semiconductor substrate within a temperature range from 600.degree. C. to 1,000.degree. C., whereby an interstitial oxygen concentration can be lowered. Subsequently, ion implantation, etc. are provided as a well region forming process, and a drive-in process is performed by means of a high temperature heat treatment. At this time, ion implantation dose is set to 9.times.10.sup.13 �cm.sup.-2 ! or less, and the temperature of the heat treatment is lowered or the duration of the teat treatment is shortened. After this, an element separation layer process is performed, and a gate oxide film, a gate electrode, a source/drain layer, a CVD oxide film, a contact hole and a metal wire are formed.

    摘要: An LOCOS film is formed on an Si substrate, a gate oxide film and a gate electrode are formed thereon, and source/drain impurities are ion implanted into the Si substrate using the gate electrode as a mask. Then, a BPSG film is formed at a film density of 1.8 g/cm.sup.3 or more. A recessed part is formed in the BPSG film by the first photolithographic process with an etching depth of 20% or more but under 100% of the thickness of the BPSG film. Thereafter, the BPSG film is fluidized by reflow treatment to shape a part which is to be a contact hole into a funnel with an "upwards convex" curvature. Finally, the part formed into the funnel is etched to make a contact hole. As a result, wiring disconnection within the contact hole can be prevented, the diffusion depth controllability for the source/drain impurities can be improved, and the fall in the impurity density in the source/drain surface can be prevented.

    摘要: In a manufacturing process of an SOI structure semiconductor device in which an MOS capacitor is located on an SOI substrate, the capacitor insulating film of the MOS capacitor is prevented from degrading due to a bimetal effect, which is caused by a thermal treatment and characteristic to the SOI substrate. A trench is formed to surround the MOS capacitor in the SOI substrate, thick oxide films are formed on sidewalls defining the trench, and the trench is filled with polysilicon to complete a trench isolation layer. Because the thick oxide films have a coefficient of thermal expansion that is different from that of a silicon semiconductor layer of the SOI substrate, the thick oxide films are able to prevent the capacitor insulating film from degrading in film quality due to the thermal treatment in the manufacturing process. As a result, an SOI semiconductor device in which an MOS capacitor on an SOI substrate offers performance comparable to an MOS capacitor on a silicon substrate can be formed.

After the transfer of a toner image of any particular color to the paper wrapped around a transfer drum, a cleaning roller assigned to the above color each collects the toner remaining on the drum and again deposits it on the drum. The drum conveys the redeposited toner to one of the developing devices storing a developer of the same color as the toner.
