Publication number: 20240005080Abstract: Aspects of the invention include systems and methods configured to provide parasitic capacitance-aware dummy metal fill methodologies. A non-limiting example computer-implemented method includes selecting one or more layers in a circuit design layout for interlayer parasitic capacitance reduction. One or more dummy metal shapes in each of the one or more layers selected for interlayer parasitic capacitance reduction is adjusted (e.g., trimmed, moved, and/or reshaped). One or more adjusted dummy metal shapes are modified until the circuit design layout satisfies design rule checking (DRC) analysis and timing is closed.Type: ApplicationFiled: June 29, 2022Publication date: January 4, 2024Inventors: LOUIS ZUOGUANG LIU, Nianzheng Cao, Sae Kyu Lee, Zhibin Ren

Patent number: 8809187Abstract: Contact with a floating body of an FET in SOI may be formed in a portion of one of the two diffusions of the FET, wherein the portion of the diffusion (such as N?, for an NFET) which is “sacrificed” for making the contact is a portion of the diffusion which is not immediately adjacent (or under) the gate. This works well with linked body FETs, wherein the diffusion does not extend all the way to BOX, hence the linked body (such as P?) extends under the diffusion where the contact is being made. An example showing making contact for ground to two NFETs (PG and PD) of a 6T SRAM cell is shown.Type: GrantFiled: September 14, 2012Date of Patent: August 19, 2014Assignee: International Business Machines CorporationInventors: Yue Tan, Zhibin Ren, Richard A.

Patent number: 8575699Abstract: SOI structures with silicon layers less than 20 nm thick are used to form ETSOI semiconductor devices. ETSOI devices are manufactured using a thin tungsten backgate encapsulated by thin nitride layers to prevent metal oxidation, the tungsten backgate being characterized by its low resistivity. The structure includes at least one FET having a gate stack formed by a high-K metal gate and a tungsten region superimposed thereon, the footprint of the gate stack utilizing the thin SOI layer as a channel. The SOI structure thus formed controls the Vt variation from the thin SOI thickness and dopants therein. The ETSOI high-K metal backgate fully depleted device in conjunction with the thin BOX provides an excellent short channel control and lowers the drain induced bias and sub-threshold swings. The structure supports the evidence of the stability of the wafer having a tungsten film during thermal processing, during STI and contact formation.Type: GrantFiled: January 9, 2013Date of Patent: November 5, 2013Assignee: International Business Machines CorporationInventors: Kevin K.
