Abstract: First, a router (400) is rotated about a shaft (406) to cause a tip end (402) of the router (400) to move in a vertical direction with respect to a conductive layer (130) while being in contact with the conductive layer (130). In this way, the router (400) is inserted into the conductive layer (130) to form an opening in the conductive layer (130).
