SEM User Interface Description ELECTRON GUN VOLTAGE: The gun voltage section allows the gun voltage to be set three different ways; (1) Using the radio buttons; (2) Clicking on the plus or minus buttons or (3) Right clicking on the voltage setting label. Clicking on a radio button causes the gun voltage to be set to the corresponding value. If the SEM is a thermionic gun, the voltage jumps to the voltage setting immediately. If it is a field emission (FE) gun and the voltage setting is higher than the present setting and greater than 10KV, the voltage will immediately be set to 10KV, then it will ramp to the desired voltage at a rate of 1KV per 0.5 seconds. Right clicking on one of the radio button labels, brings up a dialog that allows the setting to be changed. This method of setting the voltage can be configured to automatically degauss the final lens when the voltage setting is changed. Left clicking on the plus or minus buttons causes the gun voltage to increase or decrease in 100V steps. Right clicking on the buttons causes the gun voltage to increase or decrease in 1000V steps. Right clicking on the voltage setting label opens a dialog form that allows a voltage to be typed in. When the Set button is clicked, the gun voltage is set and the dialog closes. If the SEM is a thermionic gun, the voltage jumps to the voltage setting immediately. If it is a field emission (FE) gun and the voltage setting is higher than the present setting and greater than 10KV, the voltage will immediately be set to 10KV, then it will ramp to the desired voltage at a rate of 1KV per 0.5 seconds. This method of setting the voltage can be configured to automatically degauss the final lens when the voltage setting is changed. BEAM ALIGNMENT: The beam alignment section has two slider bars that are used to change the beam alignment setting. The sliders can be changed three differ ways. The adjustment slider can be clicked on and dragged until the desired setting is achieved. For small jumps, the slider bar can be clicked on between the adjustment slider and one of the ends of the control. For fine adjustments the arrows at the end of the control can be clicked on. BEAM CURRENT: For a thermionic gun, an emission current meter is displayed along with a numeric read out in the center of the meter. If the system is equipped with a motorized filament rack, auto heat and auto bias buttons are available. The auto heat button will automatically ramp the filament current to a preset level. The button will flash while the filament is heating and will be shown as pressed when the filament is done heating. The auto bias button sets the emission current to a preset level. The button will be shown in the pressed state when auto bias is active.
SEM User Interface Description IMAGE ADJUSTMENT BUTTONS: CONTRAST BRIGHTNESS CONSENSER STIMATOR FOCUS MAGNIFICATION +/- BUTTONS: Each button is a multi-function button which accept left click (fine),right click (medium) and middle click (coarse) mouse clicks. When the mouse is clicked and held down on a button, the cursor changes to an Up / Down arrow and moves to the center of the left edge of the form. Moving the mouse up or down, adjusts the control in fine medium or coarse increments depending on which mouse button is pressed and held. When one of these buttons is clicked, the button face changes to an indicator bar which shows the amount of adjustment being set. The Mag plus and Mag minus buttons are multi-function buttons which accept left click (fine), right click (medium) and middle click (coarse) mouse clicks. When the mouse is either clicked on or clicked and held down on one of the mag buttons - the mag increases or decreases in fine, medium, or coarse increments, depending on which mouse button is clicked. Image Shift: Image shift is implemented as a click and drag function. When the magnification is above a user settable minimum magnification the image is moved using beam shift by left clicking on the image area and dragging the mouse. The image shift is reset to its center position when the magnification goes below a user settable magnification.
SEM User Interface Description SCANNING MODES: PARTIAL FIELD BUTTON: In partial field mode the box can be moved by clicking on the box and dragging it to a new location. It can be resized by clicking on the lower right corner of the partial field box and dragging. In partial field mode a new partial field box can be created by clicking outside the current partial field box and dragging the mouse to create a new box. The frame averaging can also be set to 0, 1, 2, 4 and 9 in partial field mode. FULL FIELD BUTTON: In full field mode, there are six scan rates. Rapid scan and slow scan rates 1 thru 5. For PIC systems, the resolution is fixed regardless of scan rates. For X-stream Imaging systems, the resolution will change depending on the scan field chosen. For example, in rapid scan and slow scan rate 1 the image size is 640 X 480. In slow scan rate 2 the image size is 1200 X 960. In scan rates 3, 4 and 5 the image size is 2400 X 1920. Rate 4 also does 2X line averaging and rate 5 does 4X line averaging. In rapid scan the frame averaging can be set to 0, 1, 2, 4 and 9. SCAN RATE RADIO BUTTON STRIP: In full field mode the scan rate is set using this control. The scan rate can be set to rapid scan or slow scan rates 1 thru 5. Rapid scan is five frames per second. Slow scan rate 1 is 8 seconds and doubled for each selected scan rate for a maximum scan rate of 128 seconds at scan rate 5. If the image is frozen, clicking this control will unfreeze the image and set the scan mode to full field at the clicked on rate. RAPID SCAN AVERAGE STRIP: In full field rapid scan or partial field, the frame averaging is selected using this control. Frame averaging of 2 0, 2 1, 2 2, 2 4 and 2 9 frames can be selected. IMAGE FREEZE: The image must be frozen before an image can be saved. The SEM annotation can be set up so that it will appear when the image is frozen. When active, the SEM annotation along with any displayed user text, measurements or graphics will appear on saved images.
SEM User Interface Description BOTTOM STATUS BUTTONS: MAGNIFICATION LABEL: The mag label can be set to display either mag or field of view. When set to mag, left clicking on the label brings up a quick set mag form with five user configurable mag settings. Clicking on one of the radio buttons sets the mag to the radio button setting and closes the form. Right clicking on one of the radio button labels brings up a dialog that allows the setting to be changed. Right clicking on the mag label opens a mag dialog form that allows mag to be typed in and when the Set Mag button is clicked the mag is set and the dialog closes. When set to field of view the action of this label is the same except that the forms and dialogs set the field of view instead of magnification. GUN VOTAGE, WORKING DISTANCE, SPOT SIZE and SCAN ROTATION LABELS: Left clicking on any of these labels brings up a quick set form with five user configurable settings.
