PARAMETERS AFFECTING THE RESISTIVITY OF LP-EBID DEPOSITED COPPER NANOWIRES

Smith, Gabriel 01 January 2018 (has links)
Electron Beam Induced Deposition (EBID) is a direct write fabrication process with applications in circuit edit and debug, mask repair, and rapid prototyping. However, it suffers from significant drawbacks, most notably low purity. Work over the last several years has demonstrated that deposition from bulk liquid precursors, rather than organometallic gaseous precursors, results in high purity deposits of low resistivity (LPEBID). In this work, it is shown that the deposits resulting from LP-EBID are only highly conductive when deposited at line doses below 25μC/cm. When the dose exceeds this value, the resulting structure is highly porous providing a poor conductive pathway. It is also shown that beam current has no significant effect on the resistivity of the deposits. Nanowires with resistivity significantly lower than the previous best result of 67μΩ•cm were achieved, with the lowest resistivity being only 6.6μΩ•cm, only a factor of 4 higher than that bulk copper of 1.7μΩ•cm.
