Abstract
An electronic circuit device has an insulating substrate and an integrated circuit having a surface disposed opposite to and confronting a surface of the insulating substrate to form a gap therebetween. An adhesive material is disposed in the gap between the insulating substrate and the integrated circuit. Bumps project from the surface of the integrated circuit towards the surface of the insulating substrate. Electrode patterns are electrically connected to the bumps to electrically connect the integrated circuit to the electrode patterns. An adhesion-reinforcing pattern is spaced-apart from and surrounded by the electrode patterns. The adhesion-reinforcing pattern is disposed on a portion of the surface of the insulating substrate confronting a portion of the surface of the integrated circuit from which the bumps do not project.
