    摘要: Gate electrodes of an N-channel transistor and a P-channel transistor are formed on a semiconductor substrate with a gate insulator therebetween. After conducting a first thermal treatment to the gate electrodes, N-type heavily doped diffusion layers to be a source or a drain of the N-channel transistor are formed using the gate electrode of the N-channel transistor as a mask. After conducting a second thermal treatment to the N-type heavily doped diffusion layers at a lower temperature than that of the first thermal treatment, P-type heavily doped diffusion layers to be a source or a drain of the P-channel transistor are formed using the gate electrode of the P-channel transistor as a mask. Then, a third thermal treatment is conducted to the P-type heavily doped diffusion layers at a lower temperature than that of the second thermal treatment.

    摘要: On a semiconductor substrate are successively deposited a silicon dioxide film and a silicon nitride film. The silicon nitride film, the silicon dioxide film, and the semiconductor substrate are sequentially etched using a photoresist film with an opening corresponding to an isolation region, thereby forming a trench. After depositing a diffusion preventing film, there is deposited an insulating film for isolation having reflowability. Although a void is formed in the insulating film for isolation in the isolation region, the insulating film for isolation is caused to reflow, thereby eliminating the void. After that, the whole substrate is planarized by CMP so as to remove the silicon nitride film and the silicon dioxide film, followed by the formation of gate insulating films, gate electrodes, sidewalls, and source/drain regions in respective element formation regions. Thus, in a highly integrated semiconductor device having a trench isolation, degradation of reliability resulting from the opening of the void in the surface of isolation is prevented.

    摘要: An isolation which is higher in a stepwise manner than an active area of a silicon substrate is formed. On the active area, an FET including a gate oxide film, a gate electrode, a gate protection film, sidewalls and the like is formed. An insulating film is deposited on the entire top surface of the substrate, and a resist film for exposing an area stretching over the active area, a part of the isolation and the gate protection film is formed on the insulating film. There is no need to provide an alignment margin for avoiding interference with the isolation and the like to a region where a connection hole is formed. Since the isolation is higher in a stepwise manner than the active area, the isolation is prevented from being removed by over-etch in the formation of a connection hole to come in contact with a portion where an impurity concentration is low in the active area. In this manner, the integration of a semiconductor device can be improved and an area occupied by the semiconductor device can be decreased without causing degradation of junction voltage resistance and increase of a junction leakage current in the semiconductor device.
