Abstract
Devices and methods for forming a device are disclosed. The device includes a contact region disposed over a last interconnect level of the device. The device includes a final passivation layer having at least an opening which at least partially exposes a top surface of the contact region and a buffer layer disposed at least over a first exposed portion of the top surface of the contact region. When an electrically conductive interconnection couples to the contact region, the buffer layer absorbs a portion of a force exerted to form an interconnection between the electrically conductive interconnection and the contact region.
