Transistor
● Transistor Three terminations reflect light. One termination is on
the opposite side with two terminations.
Multi-scan camera Termination size: 0.5 mm sq. or larger
Note: Select [Standard] process type for the standard transistor.
Select [High Speed] process type for the power transistor.
● Pow. Tr. More than three electrodes reflect light. One flat
electrode (large electrode) is on the opposite side with
other electrodes.
Multi-scan camera Termination size: 0.5 mm sq. or larger
Power transistors can be handled by either the “Transistor” process or the
“Pow. Tr.” process.
However using the “Pow. Tr.” process can have better result than the
“Transisotor” process.
