7.3.5.2 Wait a minimum of 2 minutes.

7.3.5.3 On the High Voltage Main Power Source (TT-3, see Figure 11, High Voltage Main Power Source (TT-3)), slowly rotate the VOLTAGE ADJUST knob clockwise until the outer display on the Current Controller (TT-3/6 CONTROL, Figure 13, Current Controller) reads 6.5 KV.

7.3.6 Verify Beam Position

7.3.6.1 On the Function Generator (XY SWEEP), ensure both the LATERAL and LONGITUDINAL position LED’s are near 0 and green in color (see Figure 12, Function Generator).

7.3.6.1.1 If the lit LED is yellow (not near 0), adjust the POSITION knob until the lit LED is green and near 0.

!!! WARNING !!!

Once the beam initialization is started, DO NOT LEAVE THE SYSTEM UNATTENDED!

You must closely monitor and adjust the current, voltage, beam location, and deposition rate until the beam is turned off.

!!! WARNING !!!

7.3.7 Initialize Beam

7.3.7.1 On the Current Controller (TT-3/6, see Figure 13, Current Controller), slowly turn the EMISSION CURRENT ADJUST knob clockwise until the current is between 0.010 – 0.020 Amps.

NOTE: This step should take 1 – 2 minutes. 7.3.7.2 Wait a minimum of 5 minutes for the melt/crucible to glow orange.

7.3.8 Verify Beam

7.3.8.1 Using UV light protection, open the upper view shutter of the chamber.

7.3.8.2 Look at the melt/crucible.

7.3.8.3 If the beam size is not 50 – 75% the size of the melt/crucible, adjust the AMPLITUDE knob of the LATERAL and/or LONGITUDINAL control on the Function Generator (XY SWEEP, see Figure 12, Function Generator).

7.3.8.4 If the beam is not centered on the melt/crucible, adjust the POSITION knob of the LATERAL and/or LONGITUDINAL control on the Function Generator (XY SWEEP, see Figure 12, Function Generator).

NOTE: Rotating the LATERAL knob clockwise will move beam to the right. Rotating the LONGITUDINAL knob clockwise will move the beam up.

!!! WARNING !!!

Do not allow the beam to hit the edge of the crucible or the hearth. Sparks will be visible. Adjust the beam, as necessary, to center and size the beam.

!!! WARNING !!!

7.3.9 Reset Crystal Thickness Monitor

7.3.9.1 On the DEPOSITION CONTROLLER (see Figure 3, Deposition Controller), press the

button.

7.3.9.2 Press the 2 button to zero the thickness display.

NOTE: The crystal thickness is displayed in kiloAngstroms (1.000 KÅ = 1000Å = 100 nm = 0.1 um). TABLE 2, UNIT CONVERSIONS can be used for conversion between units.

7.4 Material Deposition

!!! WARNING !!!

Never adjust the current above 0.150 amps without Staff approval. High current settings can

damage crucibles and/or the equipment.

!!! WARNING !!!

7.4.1 VERY slowly increase the current (~0.010 Amps/minute) to an initial setting and allow the material to melt.

NOTE: The pressure will rise slightly as the material begins to melt and evaporate. The necessary temperature and current to melt varies by material.

Page 13: Denton E-Gun SOP

Denton E-Gun SOP Page 13 of 18 Revision 5-601019

7.4.2 On the Main Control Panel (see Figure 4, Main Control Panel), press the GUN SHUTTER button to open the shutter and begin deposition.

7.4.3 Using UV light protection, open the upper view shutter of the chamber and ensure the beam is scanning nicely across the material in the crucible.

7.4.3.1 If necessary, adjust the POSITION and AMPLITUDE knobs.

7.4.4 While watching the upper left corner of the DEPOSITION CONTROLLER (see Figure 3, Deposition Controller), VERY slowly turn the EMISSION CURRENT ADJUST knob on the Current Controller (TT-3/6, see Figure 13, Current Controller) until the desired deposition rate is achieved.

NOTE: The effect of the current change on the material and deposition rate will be delayed approximately 15 seconds.

NOTE: Typical deposition rates for common materials are shown in TABLE 1, COMMON MATERIAL PROPERTIES. Materials with higher melting points may have a lower deposition rate. If the actual deposition rate is much lower than typical, it is likely the crucible is cracked.

NOTE: During deposition, the chamber pressure will rise to approximately 1.0 x 10-6 Torr. 7.4.5 Verify the voltage on the Current Controller ((TT-3/6, see Figure 13, Current Controller) is

still set for 6.5 KV.

7.4.5.1 If necessary, adjust the voltage.

7.4.6 During deposition, frequently verify the deposition rate, material quantity in the crucible, and the beam position (using UV light protection).

7.4.6.1 If necessary, adjust the beam position, using the LATERAL and LONGITUDINAL knobs on the Function Generator (XY SWEEP, see Figure 12, Function Generator).

7.4.6.2 If the deposition rate drops dramatically, immediately stop deposition (see 7.5.2).

7.5 Stop Deposition

7.5.1 Wait until the desired thickness is displayed on the upper right corner of the DEPOSITION CONTROLLER (see Figure 3, Deposition Controller).

7.5.2 On the Main Control Panel (see Figure 4, Main Control Panel), press the GUN SHUTTER button to close the shutter and stop deposition.

7.5.3 On the Current Controller (TT-3/6) (see Figure 13, Current Controller), slowly turn the EMISSION CURRENT ADJUST knob counter-clockwise until the current is 0.000 Amps.

NOTE: This step should take 2 – 5 minutes. 7.5.4 Wait a minimum of 5 minutes for the melt/crucible to cool.

7.6 Deposit Additional Material(s) (Optional)

7.6.1 If another material is to be deposited, turn the crucible pocket selection knob to rotate the desired crucible pocket to the active position.

7.6.2 Repeat paragraphs 7.3.1 Program the Deposition Controller through 7.6 Deposit Additional Material(s) (Optional).

8.1.1 In October of 2003, aluminum was deposited on a glass slide in the middle of the sample holder (planetary) and another on the edge.

8.1.2 Rotation was used during the deposition cycle.

8.1.3 The thickness as measured by the crystal (Deposition Controller) was 1.000 micron.

8.1.4 Using a profilometer, the glass slide at the middle of the sample holder measured 1.2 microns.

8.1.5 Using a profilometer, the glass slide at the edge of the sample holder measured 0.93 microns.
