Abstract
A bond pad structure is provided which has a primary bond pad region electrically connected to a secondary bond pad region. The secondary bond pad region is used to test a circuit for configuration, while the primary bond pad is covered with a protective oxide. After configuration and etching to complete desired disconnections, the oxide is removed from the primary bond pad region, leaving an undamaged surface for subsequent wire bonding. The primary bond pad region and the secondary bond pad region can be a unitary structure or two separate structures.
