Abstract
A test interface board includes a first input terminal, a second input terminal, an output terminal, and a transmission line. The first input terminal receives a first test signal for testing a semiconductor device. The second input terminal receives a second test signal for testing the semiconductor device. The output terminal outputs the first test signal and the second test signal to the semiconductor device. The transmission line electrically connects the first input terminal, the second input terminal, and the output terminal such that the first test signal and the second test signal are merged.
Claims13
A test interface board comprising:
- a first input terminal configured to receive a first test signal for testing a semiconductor device;
- a second input terminal configured to receive a second test signal for testing the semiconductor device;
- an output terminal configured to output the first test signal and the second test signal to the semiconductor device;
- and
- a transmission line electrically connecting the first input terminal, the second input terminal, and the output terminal, such that the first test signal and the second test signal are merged in the transmission line and output to the output terminal,
- wherein an active period of the second test signal and an active period of the first test signal do not overlap each other.
A test system comprising:
- a semiconductor device;
- and
- a test interface board comprising input terminals configured to receive test signals for testing the semiconductor device, an output terminal configured to output the test signals as a merged signal to the semiconductor device and apply the merged signal to the semiconductor device, and a transmission line electrically connecting the input terminals and the output terminal,
- wherein the transmission line includes first partial transmission lines each connected to one of the input terminals and a second partial transmission line connected to the output terminal, and a merge point connecting the first partial transmission lines with the second partial transmission line.
