Abstract: PURPOSE:To prevent a decline of accuracy in processing due to influence of level differences when performing etching of a surface of a substrate by forming a layer to be processed on the substrate having the level differences, which has the same thickness as that of the level differences, so as to level the surface. CONSTITUTION:On a surface of a layer 22, a coating film 27 which is thick enough and whose surface is even is formed as a layer to be processed. Next, a layer 28 which is hard to transmit light is formed and this is further coated with a mask layer 23 consisting of photoresist or the like. After that, this substrate is exposed through a photomask 24. A width of an aperture of the mask layer 23 formed by development is almost same as a width W1 of a black part 25 of the photomask 24. Further, a light screening layer 28 is etched by using a mask layer 23 as a mask to form an aperture and the coating film 27 is etched by using the light screening layer 28 as a mask to form an aperture. When the layer 22 is etched, a width W3 of a formed aperture is almost the same as the width W1 of the shaded part 25.

Abstract: PURPOSE:To form grooves into a form suitable for the formation of trench capacitors and to contrive the stabilization of characteristics of the capacitors by a method wherein the grooves of capacitors are formed by isotropic etching using insulating regions as masks. CONSTITUTION:Insulating regions 2a for interelement isolation are formed in an Si semiconductor substrate 1.

After a resist mask 6a, which exposes the regions 1a with a mask alignment margin in the regions 2a, is formed, grooves 11 are each formed in the regions 1a by isotropic etching. The inner side surfaces of the regions 2a are exposed on the side surfaces of the grooves 11, the bottom surfaces of the grooves are rounded and there exists no angularity and protrusion on the inner surfaces of the grooves. The mask 6a is removed and after an Si dioxide insulating film 12 is formed on the bottom surfaces of the grooves 11, a poly Si film is deposited on the whole surface and an impurity having a conductivity type opposite to that of the substrate 1 is diffused in this film to form a polychristalline Si conducting film 13. The film 13 is used as the electrode of one of trench capacitors, which are formed thereon.
