摘要:
A method of fabricating a semiconductor device having a recess region in an insulation layer on a silicon substrate, comprising the steps of depositing a barrier metal over the entire surface of the insulation layer including the substrate surface in the recess region, depositing selectively an anti-nucleation layer on the barrier metal except in the recess region, depositing a CVD-Al layer on the barrier metal in the recess region, depositing a metal or a metal alloy inhibiting aluminum migration on the anti-nucleation layer and the barrier metal except in the recess region, and depositing a PVD-Al layer and re-flowing the PVD-Al layer, for improving the quality of aluminum grooves. The present method inhibits PVD-Al migration and grain growth, which results in preventing abnormal patterning in the semiconductor device.

A conductive pattern structure includes a first insulating interlayer on a substrate, metal wiring on the first insulating interlayer, a second insulating interlayer on the metal wiring, and first and second metal contacts extending through the second insulating interlayer. The first metal contacts contact the metal wiring in a cell region and the second metal contact contacts the metal wiring in a peripheral region. A third insulating interlayer is disposed on the second insulating interlayer. Conductive segments extend through the third insulating interlayer in the cell region and contact the first metal contacts. Another conductive segment extends through the third insulating interlayer in the peripheral region and contacts the second metal contact. The structure facilitates the forming of uniformly thick wiring in the cell region using an electroplating process.

摘要:
A bonding pad structure for a semiconductor device includes a first lower metal layer beneath a second upper metal layer in a bonding region of the device. The lower metal layer is formed such that the metal of the lower metal layer is absent from the bonding region. As a result, if damage occurs to the structure during procedures such as probing or bonding at the bonding region, the lower metal is not exposed to the environment. Oxidation of the lower metal layer by exposure to the environment is prevented, thus improving reliability of the device.
