IntlVac Nanochrome I Evaporator, intlvac_evap, Automatic

This tool provides a combination of e-beam and thermal evaporation. The tool has a six-pocket hearth for e-beam evaporation and two boats for thermal evaporation. There is a separate crystal monitor for the e-beam evaporation and for the thermal evaporation sources. The e-beam controllers allow for automatic deposition (controlled ramps, pre-heat soaks, deposition rates and final thickness). A pattern generator controls the e-beam sweep patterns (e.g. in a circle or spiral). Oxygen and nitrogen are plumbed to the chamber for reactive deposition. There is also an ion beam source for pre-cleans and film modification during the deposition.

Picture and Location


The tool is located at E56 on the Lab Map.


Process Capabilities

Cleanliness Standard

Clean and Semi-Clean only, no gold category processing is allowed.  If you have any questions regarding the use of the system, make sure to ask prior to loading your samples.

Operating Procedures



Enable tool on Badger, intlvac_evap

Vent/Load chamber:

1)       On main screen, hit “login” and log In with your ID and password. 

2)      Make sure main screen is in auto mode (select “auto”).  On bottom of screen, hit “vent” to start venting. Whenever venting, stay by the machine, since the door swings open when it is done.

          It takes about 4 minutes +/-.

3)      Crystal check, On SQC-310, main menu ( hit twice), Sensor info  life should be above 85%.

          All Metals and material are to be measured before and after deposition.

4)      Change  your gloves

5)      Inspect the chamber

6)      Inspect the shutter using a mirror or a wafer.

7)      With clean gloves remove top wafer holder, place on clean wipes, on the cart next to the tool.  Unload the dummy wafers and put in the box that has been designated for INTLVAC dummies.  Load your wafers,. The plate is numbered 1, 2, 3, 4 all wafer slots require some type of wafers.  

Install wafer  holder back into machine.

Prior to loading sources, check correct material/metal position that is posted on the front of the bell jar. Recipes have been written with designated film/crucible slot.

8)      On MDC EV-CI Indexer, make sure left-most toggle in up position in manual mode, and toggle CW or CCW to go to every pocket that you plan to evaporate, and make sure there is both a metal in that pocket and that it is the correct metal.

                 Make sure that the pockets are centered, if not this is huge issue, shut down the tool.

9)       This is time to add pallets to your target if the height is low.

10)      Close door gently and close the top and bottom flaps. On the main screen, select “pump.”

11)     Within 10 seconds both arms will drop. If it does not something is wrong and you'll have to vent and try again. Notify maintenance if it continues to fail.

Program metals:

1)      Ensure pressure is below 5e-7.   Typically two hours. You may have to re-login if timer has timed out.

2)      If timer time out and you have not reached the base pressure, Log in again and hit pump again.


a)      Move two white switches on very bottom to the up position. This is already on

b)      If for any reason the power on main panel is not on, you need to ....  On second bank of switches above bottom white switches, turn on “main power” by turning key to “on” position, and then hitting the green “on” button.

c)       All 4 lights on  high voltage  should be green


d)      All 4 lights on Emission Current unit should be green


 All 8  lights should be green as above picture shows.


1)      On main screen, while in Auto, press Profile (top left corner)

2)      Verify that the column status rotation and source 1 e-beam are lite; all others are off (not lite). For deposition only.

3)      On top left corner, press chamber to go back to Main Screen.

4)      If the system in idle, pump for one minute, this will activate the start profile.

5)      Press up Load (this saves whatever is on in the Profile-dep-only.

6)      Press Start Profile (you will hear the wafer holder rotate).

7)      On the SQC-310 is the “Deposition Controller” to select desired recipe.

8)      Select the “next menu” button until you see the button for “auto/manual”.  It should be already set “auto/manual” if not press until the order is “auto/manual” is visible. 

a.      Select “next menu” until the menu contains “process menu,” and select it.

9)      Use the scroll bar to select the correct metal recipe and press edit.

10)  Edit only the initial rate (rate of deposition) and the final thickness (total thickness deposited).  (Due to delay in shutter, the final thickness is always slightly high >   10 to 50A thicker than expected) on the display.

11)  Select “to main” to go back to main menu.

12)  Press up load again

12)  Repeat steps 6-11 for every metal layer that you plan to evaporate.

13)      Repeat steps 6-11 for every metal layer that you plan to evaporate.



  1. In Auto mode, make sure that the MDC EV-CI toggle is in Auto position.
  2. Use scroll knob to choose correct metal, and press “Select” (SOC-310 deposition Controller).
  3. Press the Sweep (RED to Green on Sweep Controller)
  4. Press the button, (Green) start on the SQC-310. If the button is red, press it so that it resets itself and it will turn green so you press start again.
  5. Watching the SQC-310 screen assuring power, dep. rate, dev % , etc . are preforming.
    Correctly, and log information into the logbook.  Monitoring e-beam through the viewport to insuring the metal heats up, and that the beam is in the center. If not press “STOP” and contact super user/ staff. You need to stay next to the system till evaporation is done.
  6. After layer is done press Stop and repeat steps from page 1, step 7 to 12 and page 2, steps 1-5.


Dual recipe:

            Turn sweep off

            Pump the system for 1 minute. Go to SQC-310 

             Start—Stop, hit next menu till you see RESET button, RESET it.

            Start from step 2 of the program Metals      




1)      When done processing all metal depositions, press Process Adv.  Button (Large Green button)

waits 10 minutes for sources to cool.

2)       After the cool down, press “Process Advance” button (Large Green button) in the center. This will start venting the chamber. (~`four minutes)

3)      Door will slightly open once vented

4)      With clean gloves remove wafer holder and place on clean wipes. Replace your wafers with 4 clean dummies back in the slots. Load wafer holder back into the machine.

5)       Check the system and vacuum it if needed.  The hose for this system is yellow with a black  nozzle tip that has a semi clean tag on it ( should not be dropped on the floor). The hose is on the left side of the      


6)      Close door gently and close the top and bottom flaps. On the main screen, select “pump.”

7)       Stay with machine until cross-over is achieved.

8)      Measure final weight of your sources.

9)      Log-off and disable, entering the beginning and final weight of metals used in badger.
