Publication number: 20190172907Abstract: An integrated circuit is formed by forming an isolation trench through at least a portion of an interconnect region, at least 40 microns deep into a substrate of the integrated circuit, leaving at least 200 microns of substrate material under the isolation trench. Dielectric material is formed in the isolation trench at a substrate temperature no greater than 320° C. to form an isolation structure which separates an isolated region of the integrated circuit from at least a portion of the substrate. The isolated region contains an isolated component. The isolated region of the integrated circuit may be a region of the substrate, and/or a region of the interconnect region. The isolated region may be a first portion of the substrate which is laterally separated from a second portion of the substrate. The isolated region may be a portion of the interconnect region above the isolation structure.Type: ApplicationFiled: February 4, 2019Publication date: June 6, 2019Inventors: Dan Carothers, Ricky Jackson, Rajarshi Mukhopadhyay, Ben Cook

Patent number: 9793106Abstract: It has been discovered that poor TDDB reliability of microelectronic device capacitors with organic polymer material in the capacitor dielectric is due to water molecules infiltrating the organic polymer material when the microelectronic device is exposed to water vapor in the operating ambient. Water molecule infiltration from water vapor in the ambient is effectively reduced by a moisture barrier comprising a layer of aluminum oxide formed by an atomic layer deposition (ALD) process. A microelectronic device includes a capacitor with organic polymer material in the capacitor dielectric and a moisture barrier with a layer of aluminum oxide formed by an ALD process.Type: GrantFiled: November 3, 2015Date of Patent: October 17, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Honglin Guo, Tim A.
