Patent Overview — US 9,831,306 B2

Title: Self-aligned gate edge and local interconnect and method to fabricate same

Patent number: US 9,831,306 B2 (application US 15/024,750; pre-grant publication US 2016/0233298 A1)

Inventors: Milton Clair Webb; Mark Bohr; Tahir Ghani; Szuya S. Liao

Original assignee: Intel Corp. Current assignee (as listed): MediaTek Inc. (the source notes listed assignees may be inaccurate and that no legal analysis was performed.)

Key dates: Priority/filing date 2013-12-19; publication of application 2016-08-11; grant 2017-11-28; anticipated expiration 2033-12-19. Legal status listed as Active.

Purpose and plain-language scope (from the supplied text): The patent concerns semiconductor device fabrication, specifically forming a self-aligned gate edge and a local interconnect, and a method of making the same. The classification data places it in the field of inorganic electric semiconductor devices, including insulated-gate field-effect transistors (IGFETs) and fin field-effect transistors (FinFETs), with manufacture or treatment of such devices. The reclassification entries further tie it to FinFET source/drain electrode structures, replacement-gate (dummy-gate) processes where final gates are self-aligned to dummy gates, gate electrodes for field-effect devices, and integration of multiple components such as IGFETs on a semiconductor substrate.

Prior-art keywords listed: gate, semiconductor, edge isolation, pair, disposed.

What the excerpt does not establish: The supplied text is a Google Patents bibliographic/classification page and does not include the abstract, claims, written description, or drawings. Therefore it does not establish the specific claim limitations, the precise structural or process scope, the number or content of claims, embodiments, or the actual technical details of how the self-aligned gate edge and local interconnect are formed. Classification entries indicate a general technical field but are not claim scope. No assertion is made here about validity, prior art, litigation, or ownership transfers.
