1. Check-in

1. Log-in on the ISIS scheduler

2. Vent Chamber

1. Touch/Click the "PC Vent" button on the right side of the screen.


3. When the venting procedure is done, the pop-up dialog box indicates "Recipe Complete".

4. Touch/Click the "Close" button.


3. Load Sample

* Note: Make sure that the power supply of e-beam evaporation is turned off behind the right door, for the sake of safety.

1. Open the door of the process chamber on the left side.

2. Touch the evaporation sources with the grounding rod; this will remove any harmful electrical charge.


3. Take out the sample chuck.

Note: As you can see in the pictures, you have to rotate the sample chuck and take it out of the hook (screws) on the chuck holder.

 

4. Using clips or Kapton tape, hold your sample(s) onto the chuck.


5. Put the chuck back to the chuck holder.

6. Put a Kapton film in front of the glass window on the back side of the left door.

4. Load Evaporating Material

1. Open the shutter(s) by touching/clicking the icon of "Source Shutter 1", the "Source Shutter 2", and/or the "E-beam Shutter" button in the "Source Shutter Control" box in the "Deposition" screen, if necessary. 


4.1 Preparation for thermal evaporation

1. Loosen the screws to take out a used evaporation boat, if necessary.

2. Replace it by a new evaporation boat, if necessary.

3. Tighten up the screws to hold the evaporation boat, if necessary.

4. Place the evaporating material onto the boat.

5. Close the shutter by touching/clicking the "Source Shutter 1" and/or the "Source Shutter 2" on the "Deposition" screen.

4.2 Preparation for E-beam evaporation


4.2.1. Remote Control

1. Open the right door of the PVD75 that has the PC monitor on the front.

2. You will find the remote control box on the middle of the tool panel. Since the default is in automatic mode, you have to change it to manual mode.

3. Press the "MENU/QUIT" button on the remote control box.

--->


4. Using the left joystick, move the inverse-highlight from "Set Pocket" to "Auto/Manual" in the left column.

5. Using the right joystick, move the pointed arrows from "Automatic Operation" to "Manual Operation" in the right column.

--->

Move the crucible liner

1. Using the left joystick, move the inverse-highlight from "Auto/Manual" to "Set Pocket" in the left column.

2. Using the right joystick, move the pointed arrows to the desired pocket in the right column.

3. Keep holding the right joystick to the right until the crucible stops rotating.

Change the crucible with the depositing material

1. Place the crucible liner with the appropriate material into the pocket.

2. Move the crucible pocket back to the original position, which is indicated to be in position on Crucible Indexer in Deposition screen. In this case, the pocket number is 4.

From Manual to Auto mode

1. Using the left joystick, move the inverse-highlight from "Set Pocket" to "Auto/Manual" in the left column. Then, press the joystick to the right.

2. Using the right joystick, move the pointed arrows from "Manual Operation" to "Automatic Operation" in the right column.

3. Press the "MENU/QUIT" button on the remote control box.

4. Make sure that the screen of the remote control box shows "Automatic Operation".

Close the shutter

1. Close the shutter by touching/clicking the "E-beam Shutter" button on Deposition screen.

3. When the pumping procedure is done, the pop-up dialog box indicates "Recipe Complete".

4. Touch/Click the "Close" button.

 

6. Conditions of The Sample Holder

6.1 Rotation Speed

1. The rotation speed of the sample holder can manually be set up in the "Deposition" and "Motion" screens.

2. The rotation speed of the sample holder can automatically be set up in the recipe.

 

7. Evaporation

7.1 Manual Operation

* Note:

1. Z-factor and density of the material need to be set up for thickness monitoring before deposition. 

2. Since these functional buttons are not available on the "Deposition" screen, the recipe is started and paused so that the Z-factor and density of the material in the recipe can be used in the manual operation.

3. Chart is opened, so that the deposition profile can also be observed.

4. You can manually deposit the material, but the deposition rate is not controlled. 

5. You can determine the conditions of the soak 1 and soak 2 processes, using the manual operation.  Then you can set up the conditions in the recipe later.
