Abstract

PROBLEM TO BE SOLVED: To provide an electroless copper composition which does not contain formaldehyde and is environmentally friendly. ;SOLUTION: The composition contains one or more copper ion sources, one or more thiocarboxylic acids, glyoxylic acid and a salt thereof, and one or more alkaline compounds for keeping the composition alkaline. The thiocarboxylic acid includes a compound having the following formula: HS-(CX1)r-(CHX2)s-COOH (wherein X1 represents -H or -COOH; X2 represents -H or -SH; and r and s are positive integers while r is 0 to 2, or 0 or 1 and s is 1 or 2). The composition is used for electroless plating. ;COPYRIGHT: (C)2008,JPO&INPIT
