Filed:

Jan 18, 2002

Appl. No.:

10/051971

Inventors:

Stephen T. Chambers - Portland OR
Valery M. Dubin - Portland OR
Andrew W. Ott - Hillsboro OR
Christine S. Hau-Riege - Milpitas CA

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H01L 2144

US Classification:

438687, 438627, 438634, 438643, 438653, 438682

Abstract:

A method, apparatus, system, and machine-readable medium for an interconnect structure in a semiconductor device and its method of formation is disclosed. Embodiments comprise a carbon-doped and silicon-doped interconnect having a concentration of silicon to avoid to forming a copper silicide layer between an interconnect and a passivation layer. Some embodiments provide unexpected results in electromigration reliability in regards to activation energy and/or mean time to failure.

Shahriar Ahmed - Portland OR
Mark Bohr - Aloha OR
Stephen Chambers - Portland OR

Anand Murthy - Portland OR

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H01L 218228

US Classification:

438322, 438341, 438360

Abstract:

The invention relates to a process of forming a bipolar junction transistor (BJT) that includes forming a topology over a substrate. Thereafter, a spacer is formed at the topology. A base layer is formed from epitaxial silicon above the spacer and at the topology. A leakage block structure is formed in the substrate by out-diffusion from the spacer. Thereafter a BJT is completed with the base layer and the spacer.

International Classification:

H01L 214763

US Classification:

438626, 438663, 438675, 438691

Abstract:

A method of fabricating a copper-containing structure, preferably within a microelectronic device, including a rapid temperature ramp from about 20 degrees Celsius up to between about 300 and 500 degrees Celsius, preferably about 400 degrees Celsius, at a rate of between about 20 and 60 degrees Celsius per second, preferably about 40 degrees Celsius per second.

International Classification:

H01L 2131

US Classification:

438771, 438240, 438637

Abstract:

The present invention provides embodiments of methods and devices for the suppression of copper hillocks. Copper hillocks are suppressed by capping the copper layer with a dielectric film before any significant growth of copper hillocks can begin using a ramped temperature dielectric deposition process. Copper hillocks are also suppressed by doping a copper layer with a dopant that will constrain the grain size of the copper during subsequent processing. These methods are applicable to the construction of MIM capacitors and interconnect structures.
