  • Publication number: 20140327142
    Abstract: Techniques for reducing the specific contact resistance of metal-semiconductor (group IV) junctions by interposing a monolayer of group V or group III atoms at the interface between the metal and the semiconductor, or interposing a bi-layer made of one monolayer of each, or interposing multiple such bi-layers. The resulting low specific resistance metal-group IV semiconductor junctions find application as a low resistance electrode in semiconductor devices including electronic devices (e.g., transistors, diodes, etc.) and optoelectronic devices (e.g., lasers, solar cells, photodetectors, etc.) and/or as a metal source and/or drain region (or a portion thereof) in a field effect transistor (FET). The monolayers of group III and group V atoms are predominantly ordered layers of atoms formed on the surface of the group IV semiconductor and chemically bonded to the surface atoms of the group IV semiconductor.

  • Publication number: 20140299993
    Abstract: The semiconductor device has insulating films 40, 42 formed over a substrate 10; an interconnection 58 buried in at least a surface side of the insulating films 40, 42; insulating films 60, 62 formed on the insulating film 42 and including a hole-shaped via-hole 60 and a groove-shaped via-hole 66a having a pattern bent at a right angle; and buried conductors 70, 72a buried in the hole-shaped via-hole 60 and the groove-shaped via-hole 66a. A groove-shaped via-hole 66a is formed to have a width which is smaller than a width of the hole-shaped via-hole 66. Defective filling of the buried conductor and the cracking of the inter-layer insulating film can be prevented. Steps on the conductor plug can be reduced. Accordingly, defective contact with the upper interconnection layer and the problems taking place in forming films can be prevented.

A planarizing dielectric material is deposited onto the wafer, filling spaces between the first copper lines. One or more trenches are etched in the planarizing dielectric material. The trenches are filled with copper to form a plurality of second copper lines that are self-aligned with the first copper lines. An electronic device is also provided.

  • Publication number: 20140232000
    Abstract: A semiconductor arrangement and methods of formation are provided. The semiconductor arrangement includes conductive lines having sidewalls angled between about 45° to about 90° relative to a plane in which bottom surfaces of the conductive lines lie. A dielectric layer is formed over the conductive lines, where forming the dielectric layer after the conductive lines are formed mitigates damage to the dielectric layer, such as by not subjecting the dielectric layer to etching. The angled sidewalls of the conductive lines cause the dielectric layer to pinch off before an area between adjacent conductive lines is filled, thus establishing an air gap between adjacent conductive lines, where the air gap has a lower dielectric constant than the dielectric material. At least one of the substantially undamaged dielectric layer or the air gap serves to reduce parasitic capacitance within the semiconductor arrangement, which improves performance.
