Blank Silicon Plate (N1265A-002)
This is an insulation board used for placing a DUT. To use this board, see the following
simple instruction.
1. Prepare a DUT and cable or wire, adequate length and quantity, for making
connections. The following accessories are available.
• N1254A-520 UHV/SHV to no connector cables for UHV High/Low, see Figure
3-13 for connection. The cables need adapters or soldering to connect DUT.
• N1254A-522 banana-banana wire (yellow) or N1254A-523 banana to no connector
wire (yellow) for Selector Output High/Low Force
• N1254A-508 or 509 connection wire for Selector Output High/Low Sense, Gate,
SMU, and chassis
• N1254A-512 SHV cable and N1254A-513 adapter for capacitance measurement
(Bias Tee terminals)
• N1254A-510 dolphin clip adapter or N1254A-511 cable lug adapter
2. Attach the blank silicon plate to the test fixture.
3. Connect cable/wire between the DUT and the fixture output terminals.
For making the Kelvin connection, Force and Sense must be connected to Force and
Sense of the socket module respectively.
Selector Output and Gate should be connected as follows.
• Selector Output High to DUT high (ex. Collector/Drain)
• Selector Output Low to DUT low (ex. Emitter/Source)
• Gate High to DUT drive (ex. Base/Gate Force)
• Gate Low to DUT low (ex. Emitter/Source Force)
HC/MC/DHCSMU via SMU 3 terminals should be connected as follows.
• SMU 3 High Force and Sense to DUT high
• SMU 3 Low Force and Sense to DUT low
• GNDU Force and Sense to DUT low
The GNDU signals will appear at the Selector Output Low terminals as shown in
Table 3-7.
4. Make sure the DUT location. The DUT must be placed on the blank silicon plate
properly.
Make enough space between the cable ends, also between the high side cable end and
the shield/chassis, for example, about 1 mm for maximum 200 V output, 6 mm for
3000 V, and 32 mm for 10 kV, to prevent discharge and any accident. Also the creepage
distance must be more than 100 mm for 10 kV.
5. Close the fixture cover before starting measurement.
