Microstructure patterned surfaces for integrated lead disk drive head suspensions

A disk drive head suspension component manufactured by a method comprising:

• depositing a layer of photoimageable polymer having an associated set of process parameters including a minimum resolution on a layer of a suspension component;
• exposing the photoimageable polymer through a photomask having a microstructure-producing region with features below the minimum resolution for the photoimageable polymer;
• developing the exposed photoimageable polymer to produce a layer of polymer having a thickness and a microstructured surface region having a pattern of depressions, each depression is located in a region corresponding to the microstructure-producing region of the photomask and is less than a thickness of the photoimageable polymer;
• depositing a layer of conductive material on the microstructured surface region of the developed polymer to produce a microstructured surface on the conductive material at a polymer-conductive material interface;
• and
• forming the layer of conductive material into one or more of a trace and a connector pad of the suspension component.
