Conductive thin film production device for electron microscope sample preparation
Osmium Plasma Coater |
Osmium Plasma Coater(OPC) is the plasma coating device that uses the DC
glow discharge method to coat conductive thin film mainly for SEM samples. |

Cross sectional TEM image alternately laminated film |
|
The repeatability of the film thickness was confirmed by alternately laminating
the osmium ultra-thin film and the plasma-polymerized film.
■Sample:Epoxy block Size:10mmφ×3mmt
|
Condition1
① |
Plasma-polymerized film and osmium film are alternately coated on epoxy
block with low current method.
Each setting film thickness is as follows.
Naphthalene 10nm 6 layers
Osmium 1nm 5 layers |
② |
Re-embedded epoxy block with epoxy resin |
③ |
After cross-sectioning with an ultramicrotome, perform TEM observation. |

Condition2
① |
Plasma-polymerized film and osmium film are alternately coated on epoxy
block by mixed gas method.
Each setting film thickness is as follows.
Naphthalene 10nm 7 layers
Osmium 1nm 6 layers(*)
(*However, only the 4th layers was discharged for 4 seconds without mixed
gas.)
