ABSTRACT:
Stiffeners for tapes, films, or other connective structures, which are configured to be secured to a semiconductor device component, such as a semiconductor die or substrate, by tape-automated bonding processes, are fabricated by stereolithographic processes and may include one or two or more layers. The stiffeners are configured to prevent torsional flexion or bending of the connective structure to which they are to be secured. The stiffeners may reinforce sprocket or indexing holes in connective structures. The stiffeners may include apertures through which intermediate conductive elements or other structures secured to the connective structure may be exposed or protrude. The stereolithographic method for fabricating stiffeners may include use of a machine vision system that recognizes the position and orientation of one or more connective structures on which at least an element of each of the stiffeners is to be fabricated so that the application of material thereto may be controlled.
