Abstract: A method of making semiconductor devices which enables control of the impurity concentration and fine patterning by making removal of residual stress due LOCOS oxidation compatible with the formation of deep wells. A selective oxide layer is formed for separating element regions on a principal plane of a semiconductor substrate, for example, a p.sup.- -type silicon substrate 1. A mask is formed (for example photoresist 47) on the surface including the selective oxide layer and impurities (for example phosphorous) of a conductivity type opposite that of the semiconductor substrate are introduced via an opening in the mask. Then the selective oxide film is annealed by a high-temperature treatment while a deep well (for example n-type deep well 50) is formed by introducing the impurities.

Abstract: A phase shifting mask is used for manufacturing a semiconductor integrated circuit device including a conductor pattern in which the line width of patterned conductor strips or the space between patterned conductor strips is not constant. For main transparent areas in the mask corresponding to the conductor pattern, auxiliary pattern segments are provided for compensating changes in the phase distribution of transmitted light caused by changes of the line width or the space. Alternately, the spaces between the conductor strips are adjusted to suppress the changes in the phase distribution of transmitted light. Whether the auxiliary pattern segments should have the phase shifting function is determined depending upon the disposition of the main transparent areas.
