Abstract
Disclosed is a method for fabricating devices, and the resulting products, using Tape Automated Bonding (TAB) technology. Via holes are formed through a flexible insulating layer, such as polyimide, and are plated through when conductive fingers are formed on one surface of the layer. The resulting structure is then bonded to a semiconductor chip by means of the conductive pads formed on the surface of the insulating layer opposite to the conductive fingers.
