Abstract: An electronic component includes a base insulative layer having a first surface and a second surface; at least one electronic device having a first surface and a second surface, wherein the electronic device is secured to the base insulative layer; at least one I/O contact located on the first surface of the electronic device; and a frame panel defining an aperture, wherein the electronic device is disposed within the aperture, and the frame panel is a multi-functional structure having a first region comprising a first material, wherein a surface of the first region secures to the base insulative layer; and a second region comprising a second material, wherein the first material and the second material differ from each other and have differing adhesability to the base insulative layer.

Abstract: A solder bump structure and an under bump metallurgical structure. An upper surface of a semiconductor substrate comprises a first conductive pad (200) disposed thereon. A passivation layer (202) overlies the upper surface. A second conductive pad (212) is disposed in an opening (204) in the passivation layer and in contact with the first conductive pad. The under bump metallurgical structure (300) encapsulates the second conductive pad, covering an upper surface and sidewalls surfaces of the second conductive pad, protecting both the first and the second conductive pads from environmental and processing effects. According to the present invention, the conventional second passivation layer is not required. Methods for forming the various structures are also presented.

Abstract: The quartz shadow ring of a conventional plasma etching apparatus is desirably coated with material which inhibits the liberation of oxygen into the plasma. Investigation has shown that the liberated oxygen degrades etching uniformity across the wafer.
