Abstract
PURPOSE:To provide a thin mounting structure capable of largely reducing the number of steps of inspecting and correcting a circuit substrate after bonding without spending a plenty of time to be spent for setting the conditions of bonding time. CONSTITUTION:A copper foil 2 formed with a finger and a reinforcing resin substrate 6 are bonded on and under an resin substrate 5 (the material of which is polyimide coated with epoxy adhesive coating) of the side formed with the finger, are etched with the bonded copper foil to a pattern, thereby forming a finger 2a. When an IC chip 3 is bonded and sealed with resin, the substrate 5 is reduced in the size of a device hole 5a smaller than the profile size of the chip. Accordingly, the substrate 5 is interposed between the upper surface to the chip 3 and the finger 2a, thereby completely electrically insulating the space between the edge and the finger on the outer peripheral surface of the chip 3.
