     (b) R 1 -S-(CH 2 O) n -R 2 -SO 3 M(여기서, R 1 은, 수소 원자, -(S) n -(CH 2 O) n -R 2 -SO 3 M, 또는 -CS n -(CH 2 O) n -R 2 -SO 3 M이고, R 2 는 3~8개의 탄소 원자를 포함하는 알킬렌기이고, M은 수소 원자 또는 알칼리 금속이며, n은 0 또는 1이다)의 화학식으로서 표시되는 화합물을 함유하는 황산구리 도금조를 사용한다. 구리 도금은, 하지층(下地層; seed layer)을 포함하는 하나의 전극과 상기 황산구리 도금조에 침지(浸漬)된 또 하나의 전극과의 사이에, 정전해(正電解) 시간에 대하여 1~50msec, 역전해(逆電解) 시간에 대하여 0.2~5msec, 및 정지 시간에 대하여 1~50msec의 주기로 전류를 역전시킴으로써 실시한다.
