摘要:
A silicon layer is formed on a silicon substrate by an epitaxial growth, and, then a surface of the silicon layer is oxidized. The surface of the silicon layer is cleaned, to remove foreign material generated on the surface of the silicon layer during the epitaxial growth.

A semiconductor device includes cylindrical capacitors each including corresponding cylindrical electrodes. Each cylindrical electrode includes hemispherical silicon grains. The hemispherical silicon grains protruding from an upper region of the cylindrical electrode have a large size, and the hemispherical silicon grains protruding from a lower region of the cylindrical electrode have a small size or the lower region of the cylindrical electrode has no hemispherical silicon grains.
摘要:
A first space partitioned by first and second line patters (52, 53) is filled with a multilayer film that is composed of a first silicon film (55) having a high impurity concentration (a first concentration) relative to a standard plug impurity concentration (a third concentration) and a second silicon film (57) having a low impurity concentration (a second concentration) relative to the standard plug impurity concentration, and is divided by forming a groove (59) using a mask film (58) on the side wall of the second line pattern (53). As a result, expansion of a seam, which is formed only on the second silicon film (57) having a low impurity concentration, is suppressed. After that, an isolation insulating film is embedded in the groove and impurity diffusion is carried out by a heat treatment, so that divided plugs (60) as a whole are made to have the third concentration.
摘要:
A semiconductor device comprises a material layer including a first surface and a trench with an opening in the first surface. The trench is formed in the material layer. The trench comprises a tapered portion and a vertical portion. The tapered portion is in contact with the opening and comprises a scalloping-forming trench. The vertical portion has a substantially vertical sidewall. A width of the scalloping-forming trench is larger than a width of the vertical portion.
