Selective segment via plating process and structure

A selective segment via plating process for manufacturing a circuit board selectively interconnects inner conductive layers as separate segments within the same via. Plating resist is applied to a conductive layer of an inner core and then stripped off after an electroless plating process. Stripping of the electroless plating on the plating resist results in a plating discontinuity on the via wall. In a subsequent electroplating process, the plug non-conductive layer can not be plated due to the plating discontinuity. The resulting circuit board structure has separate electrically interconnected segments within the via.

Dielectric anti-reflective coating surface treatment to prevent defect generation in associated wet clean

A method for preventing the formation of watermark defects includes the steps of forming a pad oxide, a silicon nitride layer and a silicon oxynitride layer over a semiconductor substrate. A photoresist mask is formed over the resulting structure, with the silicon oxynitride layer being used as an anti-reflective coating during exposure of the photoresist material. An etch is performed through the photoresist mask, thereby forming a trench in the substrate. The photoresist mask is stripped, and the silicon oxynitride layer is conditioned. For example, the silicon oxynitride layer may be conditioned by a rapid thermal anneal in the presence of oxygen or nitrogen. A wet clean step is subsequently performed to remove a native oxide layer in the trench. The conditioned silicon oxynitride layer prevents the formation of watermarks during the wet clean process.
