发明名称 ALKALINE AQUEOUS SOLUTION COMPOSITION USED FOR WASHING OR ETCHING SUBSTRATES
摘要 An alkaline aqueous solution composition is provided to improve prevents electrical feature and to ensure improvement of throughput by preventing metal from being absorbed to the surface of a substrate. An alkaline aqueous solution composition contains a chelating agent and a alkali component expressed as the general equation(1). In the equation, R may be acceptable that arbitrary 1 or 2 hydrogens are substituted with an identical or different substitution radical, and is C 2~6 alkylene group, 1, 2- cyclohexylene group or 1, 2- phenylene group; ring A and B may be acceptable that arbitrary 1 or 2 hydrogens are substituted with an identical or different substitution radical, and is a benzene ring.
