The Hummer sputter coater is used to sputter a thin gold layer on different small samples (up to 100 mm wafers).
One of the most effective ways to counter the problems with charging on non-conducting samples during SEM investigations is to apply a conducting coating to the surface. The Hummer sputter coater is an instrument that allows you to coat small samples with a gold layer. When securely grounded, i.e. connected electrically with a sample holder using aluminium tape or clamps the gold layer will effectively eliminate all charging problems in the SEM.
The Hummer sputter coater is located in servie area Cx1 in the clearoom.

Sputter coater 03 (Cressington) located in the 346 basement, room 907
The Sputter coater is used to sputter a thin gold layer on different small samples (smaller than 100 mm wafers). It is not allowed to use the sputter coater for other purposes.
One of the most effective ways to counter problems with charging on non-conducting samples during SEM investigations is to apply a conducting coating to the surface.

When securely grounded, i.e. connected electrically with a sample holder using aluminium tape or clamps, the gold layer will effectively eliminate all charging problems in the SEM.
The sputter coater consists of a sputter chamber with a gold target and a stage. The stage consist of four smaller stages. These small stages can rotate individually in a planetary motion, when the entire stage rotates at the same time. The rotation speed can be controlled. Small samples can be mounted on a SEM pinstub holder (only use the smallest pinstubs) with carbon pads and then placed on one of the small stages. The maximum sample size is a 4 inch wafer. If your sample is larger than one of the four small stages, or if the sample is not fastened on a pinstub, the stage rotation should not be activated.
The machine is controlled by a control panel. The sputter process will be done automatically, but the sputter time can be adjusted.
Please note that the sputter rate and uniformity have not been measured yet.
Argon is used as a sputter gas to generate a plasma in the sputter chamber and to vent the chamber.
