5 What does it do? The Diode Pumped Solid State (DPSS) Laser is a source of light produced by a solid state laser which is charged by a pumping light emitting diode. After charging (~ 1 ms) the DPSS can generate short light pulses (< 4 ns) with high intensity (> 20 µj). The DPSS Laser is attached to the Diode Laser Station or Laser Station and operated for optical Fault Injection (FI) attacks on semiconductors. Figure 1 DPSS Laser DPSS Laser QSG / 29

6 How to build a setup Follow the next steps to install the DPSS Laser on the Diode Laser Station or Laser Station. ESD sensitivity The laser head is very sensitive to electro static discharge. To prevent damage to the laser head: keep the red colored ESD protection plug connected to the laser head whenever the laser head is not connected to the power supply. Prevent ESD by proper grounding of equipment and your body during connection or disconnection of cables or plugs to laser head or power supply When connecting cables to the laser head, make sure the other side of the cable has been connected to the other equipment first and this equipment has been grounded DPSS Laser QSG / 29

12 Installation of required drivers Two drivers can be installed. One required driver is for the attenuator control and one optional driver for setting the laser parameters. The attenuator controller driver controls the attenuator which influences the optical output power of the laser. This driver is also required for Inspector software. The installation of the optional driver is described in the next chapter. Installation of Newport attenuator driver and detecting COM-port The attenuator reduces the laser power. The attenuator is positioned between laser pulse generator and output fiber. The attenuator keeps its reduction value during power off. The reduction value can be influenced via Inspector software or via the Conex-AGP GUI after installation of the attenuator driver. The attenuator driver and Conex-AGP GUI installation file can be found at the USB memory key which is part of the shipment: CONEX-AGP 2.0.2\setup.exe. Run this set-up executable as administrator. After driver installation, please start the Windows device manager. While keeping the device manager open, insert the USB cable connector from the Attenuator Controller into a USB port at your computer. The USB device will be detected and identified, and a Newport CONEX-AGP USB Serial Port (COMxx) entry is added to device group COM & LPT. Remember the port number xx, as you will need it for the configuration of Conex- AGP GUI and Inspector. Configure attenuator COM port baud rate in Inspector Now configure the communication between Inspector and the Attenuator Controller to use baud rate to This is done via the menu bar in Inspector: Select Menu bar > Tools > Hardware Manager > Raw I/O devices > COMXX Select the Settings button in the top right-hand corner DPSS Laser QSG / 29

13 Enter for baud rate bps, and press Enter. Close the Settings dialog, and the Hardware Manager Attention: If the baud rate has not been configured correctly. It is then required, before configuring again the baud rate, to reboot the Attenuator Controller, by disconnecting and reconnecting the USB cable. Then restart Inspector. 0% transmission position of the attenuator When using the Conex-AGP GUI or Inspector, you need to be aware of the attenuator position which corresponds to 0% transmission. This position is indicated in the Final Test Report as delivered by the manufacturer. Figure 8 Final test report shows 0% transmission position In the example above, the 0% transmission position equals 12. If you are using the Inspector software, you need to enter this value as setting for the DPSS laser via the Hardware Manager by the following steps: DPSS Laser QSG / 29

14 Select Menu bar > Tools > Hardware Manager > Add device > Dpss laser Choose a title for the DPSS laser in the Name field (e.g. COMMXX) The Laser port field is not used yet in Inspector version 4.9 Select COMXX for the Attenuator port Set Attenuator offset to the value found in the Final test report (in this example 12 degrees) Press OK to store the values Close Hardware Manager DPSS Laser QSG / 29

17 9. The laser is now ready to fire. The laser will fire upon a positive rising edge coming from the trigger source connected to TRIGGER connector of the Power Supply Unit. Integration with Riscure products The laser control is integrated in Inspector software and can be trigger via the VC Glitcher or Spider. Inspector software You need to start with the installation of the attenuator interface. Please follow the steps in section Installation of Newport attenuator driver and detecting COM-port and 0% transmission position of the attenuator. The DPSS laser is now supported in the Perturbation 2 framework but not in the legacy modules. Select any module out of the Perturbation > Single XYZ group. In the tab Glitch Source, you will find the pull down list Glitch source which will also contain the dpss laser (e.g. COMXX). The only difference in control between the DPSS laser and the diode laser is the power setting; see section Adjusting the laser attenuator. The training and tutorials for the diode laser can be used for the DPSS laser as well. VC Glitcher or Spider The DPSS laser needs to be triggered to fire a pulse. Triggering can be done by: VC Glitcher via connector digital pulse out Spider via connector glitch out 1 or glitch out 2 This output needs to be connected to TRIGGER connector (6) of the laser power supply. The timing conditions with regards to the minimum trigger pulse duration and trigger pulse delay need to be obeyed. See the Specification section for the appropriate values. Adjusting the laser attenuator DPSS Laser QSG / 29

18 The laser optical power is influenced by the setting of the attenuator. Adjusting the attenuator via Inspector or Conex-AGP GUI takes time. Adjustment from 100% to 0 % takes approximately 45 seconds. This adjustment duration may negatively influence the time to explore the correct set of parameters (e.g. location, timing and power level) to run and effective fault injection analysis. For that reason, the user should put the change of attenuator settings in the outer loop of the exploration to minimize the number of attenuator adjustments. Since the attenuator is a moving part, reducing the number of adjustments will positively influence the life time of the attenuator. Adjusting the laser spot Once the camera image is focused, the Fiber Coupler can be adjusted to fine-tune the laser spot on the die (Figure 10b) position the laser spot within the camera field of view (Figure 10c) DPSS Laser QSG / 29

19 Figure 10 Fiber Coupler adjustment controls Focusing the laser spot size without Spot Size Reducer Please follow the next steps to adjust the Fiber Coupler (Figure 10b): Unlock the locking ring (2) Unlock the fiber-end form the SMA connector on top of the Fiber Coupler but keep the fiber end inside. Rotate the head (1) of the Fiber Coupler while observing the effect in the camera view to focus the laser spot. To visualize the laser spot, the laser needs to fire. To fire the laser, you need to provide the laser with trigger pulses. This can be done via Inspector and VC Glitcher: o Make connections between the DPSS laser and PC via VC Glitcher. o Select Inspector > Perturbation > Single XYZ > Smart Card > Protocol. o Select Perturbation tab DPSS Laser QSG / 29

20 o Set Glitch length 1 at 250 ns or longer. o Select Glitch Source tab o Set Glitcher connected VC Glitcher o Set Glitch source to COMXX o Put a dummy object underneath the microscope to avoid damaging your device under test. o Press Test glitch source and increase Test glitch source power until the spot becomes visible. After focusing, fix the fiber end and apply locking ring again Focusing the laser spot size with Spot Size Reducer When a Spot Size Reducer tube is inserted in-between Fiber Coupler and microscope, you may need to perform the focusing procedure again but this time for the Spot Size Reducer instead of the Fiber Coupler. The head of the spot size reducer can be rotated relative to the body of the Spot Size reducer. This will influence the focus of the laser spot. Please refer to the Quick Start Guide of the Laser Station for further details. Aligning the laser spot position Two diagonal corners of the Fiber Coupler base are fitted with adjustment screws (3). Adjust the screws while observing the effect in the camera view. The screw can be adjusted with a hexagonal wrench which is supplied with the Diode Laser Station of Laser Station. Protect you Device under Test The DPSS laser generates pulses of high intensity which can easily damage the device under test. It is strongly advised to start the perturbation analysis at a very DPSS Laser QSG / 29

21 low power level e.g. several percent. After shooting laser pulses at various locations over the area of interest and at various moments within the time interval of interest without any changes in the device s response, the analyst can tune up the power level to run a succeeding scan over area and time interval at a higher power level. Keep the fiber end clean The fiber end can become easily contaminated by dust or dirt if the fiber end touches another object e.g. your finger. The contamination will reduce the laser power. The contamination should be removed as soon as possible to avoid permanent contamination. The contamination can often be removed by 99% pure alcohol or acetone. Fix fiber position and avoid mechanical stress Bending the fiber influences the set of optical modes inside the fiber and will have an influence on the optical output power coming out of the fiber up to +/- 10%. It is advised the fix the fiber to a certain position to avoid changing the bending radius and power level. The first part of the fiber directly at the exit of the laser head should be free of mechanical stress. Stress at the start of the fiber may influence the output power to a much greater extend DPSS Laser QSG / 29
