Connecting bar

Abstract

A connecting bar electrically connects separate circuit zones of an integrated circuit. The connecting bar is formed by a main portion that is a conductive strip extending above separate circuit zonesto be interconnected. The conductive strip is separated from the integrated circuit by a dielectric except at the circuit zones to be interconnected. The connecting bar further includes secondary portions that are conductive pads passing through the dielectric in a vertical direction from the circuit zone to the conductive strip.

Description

[0001] This application claims priority from French Patent Application No. 1750540, filed January 23, 2017, the disclosure of which is incorporated by reference in its entirety to the fullest extent permitted by law. technical field [0002] This application relates to the field of integrated circuits, and more particularly, to the production of tie bars that form electrical connections between elements of an integrated circuit, such as between the sources of multiple transistors formed in a thin silicon-on-insulator (SOI) layer . Background technique [0003] SOI transistors are an alternative to bulk silicon transistors. SOI transistors are formed in and on a thin layer of silicon separated from the silicon wafer by a layer of insulator, usually silicon dioxide. [0004] It has been observed that, in many cases, SOI integrated circuits in which tie bars connect multiple elements of the circuit contain defects. Contents of the invention [0005] Accordingly, one embodim...
