PROBLEM TO BE SOLVED: To provide a TEG chip which allows for measurement of the characteristics while separating a triac to the single level transistor of the smallest unit, while determining the acceptability.SOLUTION: A TEG chip (10) is a triac having an N type substrate (310), P type diffusion layers (320, 33), N type diffusion layers (34, 35, 36), a first electrode (T1), a second electrode (T2), and a gate electrode (G), and has a test electrode (7) for detecting the potential of the N type substrate (310).SELECTED DRAWING: Figure 4 |
