Patent number: 9564442Abstract: A method of forming contacts for a semiconductor device structure comprises forming contact holes extending into neighboring semiconductive pillars and into a nitride material of nitride-capped electrodes. Composite structures are formed within the contact holes and comprise oxide structures over sidewalls of the contact holes and nitride structures over the oxide structures. Conductive structures are formed over inner sidewalls of the composite structures. Additional nitride-capped electrodes are formed over the conductive structures and extend perpendicular to the nitride-capped electrodes. Pairs of nitride spacers are formed over opposing sidewalls of the additional nitride-capped electrodes and are separated from neighboring pairs of nitride spacers by apertures extending to upper surfaces of a portion of the neighboring semiconductive pillars. Portions of the oxide structures are removed to expose sidewalls of the portion of the neighboring semiconductive pillars.Type: GrantFiled: April 8, 2015Date of Patent: February 7, 2017Assignee: Micron Technology, Inc.Inventors: Sanh D.

Patent number: 9564443Abstract: After formation of trench capacitors and source and drain regions and gate structures for access transistors, a dielectric spacer is formed on a first sidewall of each source region, while a second sidewall of each source region and sidewalls of drain regions are physically exposed. Each dielectric spacer can be employed as an etch mask during removal of trench top dielectric portions to form strap cavities for forming strap structures. Optionally, selective deposition of a semiconductor material can be performed to form raised source and drain regions. In this case, the raised source regions grow only from the first sidewalls and do not grow from the second sidewalls. The raised source regions can be employed as a part of an etch mask during formation of the strap cavities. The strap structures are formed as self-aligned structures that are electrically isolated from adjacent access transistors by the dielectric spacers.Type: GrantFiled: January 20, 2014Date of Patent: February 7, 2017Assignee: International Business Machines CorporationInventors: John E.

Patent number: 9564444Abstract: At least one dielectric pad layer is formed on a semiconductor-on-insulator (SOI) substrate. A deep trench is formed in the SOI substrate, and a combination of an outer electrode, a node dielectric, and an inner electrode are formed such that the top surface of the inner electrode is recessed below the top surface of a buried insulator layer of the SOI substrate. Selective epitaxy is performed to fill a cavity overlying the inner electrode with an epitaxial semiconductor material portion. A top semiconductor material layer and the epitaxial semiconductor material portion are patterned to form a fin structure including a portion of the top semiconductor material layer and a portion of the epitaxial semiconductor material portion. The epitaxial semiconductor material portion functions as a conductive strap structure between the inner electrode and a semiconductor device to be formed on the fin structure.Type: GrantFiled: October 3, 2015Date of Patent: February 7, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Kevin K.

Patent number: 9564445Abstract: Trench capacitors can be formed between lengthwise sidewalls of semiconductor fins, and source and drain regions of access transistors are formed in the semiconductor fins. A dummy gate structure is formed between end walls of a neighboring pair of semiconductor fins, and limits the lateral extent of raised source and drain regions that are formed by selective epitaxy. The dummy gate structure prevents electrical shorts between neighboring semiconductor fins. Gate spacers can be formed around gate structures and the dummy gate structures. The dummy gate structures can be replaced with dummy replacement gate structures or dielectric material portions, or can remain the same without substitution of any material. The dummy gate structures may consist of at least one dielectric material, or may include electrically floating conductive material portions.Type: GrantFiled: January 20, 2014Date of Patent: February 7, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: John E.

Patent number: 9564446Abstract: A double sidewall image transfer process for forming FinFET structures having a fin pitch of less than 40 nm generates paired fins with a spacing determined by the width of a sidewall spacer that forms a second mandrel. Here, the fin pairs are created at two different spacings without requiring the minimum space for the standard sidewall structure. An enlarged space between paired fins is created by placing two first mandrel shapes close enough so as to overlap or merge two sidewall spacer shapes so as to form a wider second mandrel upon further processing. The fin pair created from the wider second mandrel is spaced at about 2 times the fin pair created from the narrower second mandrel. For some circuits, such as an SRAM bitcell, the wider second mandrel can be utilized to form an inactive fin not utilized in the circuit structure, which can be removed. In some embodiments, all dummy inactive fins are eliminated for a simpler process.Type: GrantFiled: December 16, 2015Date of Patent: February 7, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Mary E.
