Beam-induced deposition of low-resistivity material |
摘要 |
An improved method of beam deposition to deposit a low-resistivity metal. Preferred embodiments of the present invention use a novel focused ion beam induced deposition precursor to deposit low-resistivity metallic material such as tin. Applicants have discovered that by using a methylated or ethylated metal such as hexamethylditin as a precursor, material can be deposited having a resistivity as low as 40 μΩ·cm. |

1. A method of depositing a low resistivity material onto a substrate, the method comprising:
directing a precursor gas comprising a methylated or ethylated tin toward a surface of the substrate; irradiating the surface of the substrate with an ion beam in the presence of the precursor gas, the precursor gas dissociating in the presence of the ion beam to deposit a material on the surface of the substrate; wherein the deposited material contains tin dissociated from the precursor gas and has a resistivity of 50 μΩ·cm or lower upon deposition. |
