摘要:There is a method and apparatus for plating in which electroless copper platingis performed in a contact hole and an interconnect trench on a minute scale of asemiconductor integrated circuit device, and a plating structure. Organic material
originated from an organic gas carried over from the preceding step is removed from theinner surface of a blind hole, thereafter the surface of the barrier layer is subjected topredetermined pretreatments comprising a hydroxylation treatment, a couplingtreatment, a Pd colloidal solution treatment and the like, and following the
pretreatments, electroless plating with copper is effected desirably under influence ofultrasonic waves. Hence, a uniform, good quality plating layer is formed inside andoutside the hole and a CMP processing following the plating is performed with ease.
