| 選択的トレンチフィリングCuめっきによる微細配線形成プロセス Advanced Trench Filling Process by Selective Copper Electrodeposition for Ultra Fine Printed Wiring Board Fabrication |
中野 広 Hiroshi NAKANO |
| ＜要旨＞ A
Trench-filling process for fabricating ultra-fine-pitch printed wiring
boards was developed by combining nano-imprint lithography (NIL) and
selective copper deposition. Copper was electrodeposited selectively
inside the trenches fabricated in the dielectric layer by NIL without
causing excess deposition on the surface. The selective deposition was
realized by a novel electrolyte containing an inhibiting additive. The
process of recessed interconnections is described. Keywords: Copper / Electrodeposition / Selective Deposition / Trench Filling Process / Nano-Imprint Technology |

| イオン液体を用いた新しい電子顕微鏡観察法の開発 Development of New Electron Microscopy Techniques Using Ionic Liquids |
桑畑 進 Susumu KUWABATA |
| ＜要旨＞ Ionic
liquids possess negligible vapor pressure that allows us to put the liquids
in a vacuum chamber without any vaporization of the liquid. This fact
led us to attempt the observation of ionic liquids by a scanning electron
microscope (SEM). Surprisingly it has been found that ionic liquids can
be observed without any charging of the liquid. This result means that
ionic liquids behave as electrically conducting materials in SEM observation.
Based on this finding, it was initiated to develop new electron microscopy
techniques; putting ionic liquids on the surfaces of insulating materials
for their observation by SEM, SEM observation of bio-materials wetted by ionic
liquids, and SEM observation of chemical reactions occurring in ionic
liquids. In the latest case, elemental analysis by electron dispersive
X-ray spectroscopy conducted at the same time was also found to be a
significant technique to clarify reaction mechanisms. Keywords: Ionic Liquid / Electron Microscope / SEM / SEM Observation of Wetted Samples / In Situ SEM Observation of Chemical Reactions / Energy Dispersive X-Ray Spectroscopy / EDX / In Situ EDX Analysis |
