Semiconductor device with advanced pad structure resistant to plasma damage and metnod for forming same
A connective structure for bonding semiconductor devices and methods for forming the same are provided. The bonding structure includes an alpad structure, i.e., a thick aluminum-containing connective pad, and a substructure beneath the aluminum-containing pad that includes at least a pre-metal layer and a barrier layer. The pre-metal layer is a dense material layer and includes a density greater than the barrier layer and is a low surface roughness film. The high density pre-metal layer prevents plasma damage from producing charges in underlying dielectric materials or destroying subjacent semiconductor devices.

Method for aligning micro-electronic components
Alignment of a first micro-electronic component to a receiving surface of a second micro-electronic component is realized by a capillary force-induced self-alignment, combined with an electrostatic alignment. The latter is accomplished by providing at least one first electrical conductor line along the periphery of the first component, and at least one second electrical conductor along the periphery of the location on the receiving surface of the second component onto which the component is to be placed. The contact areas surrounded by the conductor lines are covered with a wetting layer. The electrical conductor lines may be embedded in a strip of anti-wetting material that runs along the peripheries to create a wettability contrast. The wettability contrast helps to maintain a drop of alignment liquid between the contact areas so as to obtain self-alignment by capillary force. By applying appropriate charges on the conductor lines, electrostatic self-alignment is realized, which improves the alignment obtained through capillary force and maintains the alignment during evaporation of the liquid.
