景点英语摘要:PURPOSE: To obtain a metal coat including a lf aligning contact easily, by patterning specified sites of trenches furthermore while preventing the undesired etching of a dielectric layer using a cond etching stop layer, and forming lf-aligned windows in a first dielectric layer. CONSTITUTION: A photoresist for rever metal patterning is removed, a new photoresist layer 35 is deposited, and patterning by a pattern for windows is performed. A pattern for windows is formed by standard lithography. Windows formed in the photoresist are larger than specified dimensions required. Accordingly, an etching stop layer 29 performs lf aligning at the etching time of the next window. Namely, the layer 29 prevents the etching of a dielectric material below it, and a lf-aligned window is formed by doing that way. A dielectric layer 23 is etched, and specific sites of a board below it are expod. Only the sites expod during rever metal etching are etched, and electric contacts are formed.
