    摘要: A planarized multi-layer metal bonding pad. A first metal bonding pad layer (13) that defines a metal bonding pad is provided. A first dielectric layer (14) is provided with a multitude of vias (17) that covers the first metal bonding pad layer (13), thereby exposing portions of the first metal bonding pad layer (13) through the multitude of vias (17) in the first dielectric (14). A second metal bonding pad layer (18) that further defines the metal bonding pad is deposited on the first dielectric layer (14) making electrical contact to the first metal bonding pad layer through the multitude of vias (17). Planarization of the second metal bonding pad layer (18) is achieved by having the second metal bonding pad layer (18) cover the first dielectric layer (14) and making contact through the vias (17).

    摘要: A method of manufacturing a semiconductor component includes providing a composite substrate (300) with a dielectric portion and a semiconductor portion and growing an epitaxial layer (400) over the composite substrate. The epitaxial layer has a polycrystalline portion (402) over the dielectric portion of the composite substrate and also has a monocrystalline portion (401) over the semiconductor portion of the composite substrate. A first dopant is diffused into the monocrystalline portion of the epitaxial layer to form an emitter region in the monocrystalline portion of the epitaxial layer while a second dopant is simultaneously diffused into the monocrystalline portion of the epitaxial layer to form an enhanced portion of the base region.

    摘要: Metal step coverage is improved by utilizing a multiple step metallization process. In the first step, a thick portion of a metal layer is deposited on a semiconductor wafer at a cold temperature. The remaining amount of metal is deposited in a second step as the temperature is ramped up to allow for reflow of the metal layer through grain growth, recrystallization and bulk diffusion. The thick portion of the metal layer deposited at the cold temperature is of adequate thickness so that it remains continuous at the higher temperature and enhances via filling.

    摘要: A residue-free plasma etch of high temperature aluminum copper metallization is provided by the use of a single plasma etcher. The metallization layer is covered by a protective oxide layer. This structure is then placed in the single etcher and a vacuum is established. The protective oxide layer is then etched and without breaking the vacuum or removing the structure from the etcher the metal layer is also etched. This results in the etched surface being residue-free.
