Dielectric Trenches, Nickel/Tantalum Oxide Structures, And Chemical Mechanical Polishing Techniques

View page
US Patent:
7964508, Jun 21, 2011
Filed:
Aug 21, 2008
Appl. No.:
12/196065
Inventors:
Sergey Savastiouk - San Jose CA, US
Valentin Kosenko - Palo Alto CA, US
James J. Roman - Sunnyvale CA, US
Assignee:
Allvia, Inc. - Sunnyvale CA
International Classification:
H01L 21/302
US Classification:
438692, 438691, 438693, 216 90
Abstract:
A portion of a conductive layer () provides a capacitor electrode (). Dielectric trenches () are formed in the conductive layer to insulate the capacitor electrode from those portions of the conductive layer which are used for conductive paths passing through the electrode but insulated from the electrode. Capacitor dielectric () can be formed by anodizing tantalum while a nickel layer () protects an underlying copper () from the anodizing solution. This protection allows the tantalum layer to be made thin to obtain large capacitance. Chemical mechanical polishing of a layer () is made faster, and hence possibly less expensive, by first patterning the layer photolithographically to form, and/or increase in height, upward protrusions of this layer.

Structures With Through Vias Passing Through A Substrate Comprising A Planar Insulating Layer Between Semiconductor Layers

US Patent:
8431431, Apr 30, 2013
Filed:
Jul 12, 2011
Appl. No.:
13/181006
Inventors:
Valentin Kosenko - Mountain View CA, US
Sergey Savastiouk - Saratoga CA, US
Assignee:
Invensas Corporation - San Jose CA
International Classification:
H01L 21/00
US Classification:
438 98
Abstract:
A through via contains a conductor () passing through a substrate (). The substrate can be SOI or some other substrate containing two semiconductor layers () on opposite sides of an insulating layer (B). The through via includes two constituent vias () formed from respective different sides of the substrate by processes stopping on the insulating layer (B). Due to the insulating layer acting as a stop layer, high control over the constituent vias' depths is achieved. Each constituent via is shorter than the through via, so via formation is facilitated. The conductor is formed by separate depositions of conductive material into the constituent vias from each side of the substrate. From each side, the conductor is deposited to a shallower depth than the through-via depth, so the deposition is facilitated. Other embodiments are also provided.

US Patent:
20120228778, Sep 13, 2012
Filed:
Mar 7, 2011
Appl. No.:
13/042186
Inventors:
Valentin Kosenko - Palo Alto CA, US
Sergey Savastiouk - Saratoga CA, US
International Classification:
H01L 23/48
H01L 21/441
US Classification:
257774, 438668, 257E23011, 257E21477
Abstract:
A through via () contains a conductor () passing through a substrate () for connection to an integrated circuit element. The through via consists of two segments () formed from respective different sides () of the substrate and meeting inside the substrate. Each segment is shorter than the entire via, so via formation is facilitated. The second segment is etched after deposition of an etch stop layer () into the first segment. Due to the etch stop layer, the first segment's depth does not have to be rigidly controlled. The conductor is formed by separate depositions of conductive material into the via from each side of the substrate. From each side, the conductor is deposited to a shallower depth than the via depth, so the deposition is facilitated. Other embodiments are also provided.
