Title: Method and device for testing wiring characteristics
Inventor: OFUJI SHINICHI
IPC: G01R31/26
Filed: 1994-06-02
Abstract: PURPOSE:To reduce the temperature difference between specimen levels which is generated by Joule heat when large current density is used at the time of testing, by installing a testing current control equipment which uses the detection temperature detected from a wiring for temperature detection as an input, and uses the testing current applied to a wiring to be tested as an output. CONSTITUTION:A current having a specified density is applied to an Al wiring 3 to be tested in the temperature range of a test tank from the room temperature to 175 deg.C. From the potential difference between both ends of the wiring at the time of thermal equibrium, the resistance value and its temperature coefficient are obtained, and the effective wiring surface temperature is derived from the resistance value. At the same time, resistance is measured from the potential difference between both ends of an adjacent Al wiring 4 for temperature detection to which a current having a specified current density is applied. From the value, a calibration graph is formed which can obtain the effective wiring surface temperature of the Al wiring 3 to be tested at each of the test tank temperatures and for test current density. Thereby, when a large current density is used, the effective temperature in the vicinity of the surface of the wiring to be tested can be constantly maintained at a set temperature between each of the test levels.

Filed: 1995-05-19
Abstract: PURPOSE: To prevent monostabilization and the degradation in contrast. CONSTITUTION: An information signal is impressed from an information signal impression circuit (not shown in Fig.) to a liquid crystal panel P and ferroelectric liquid crystals attain a first optically stable state or second optically stable state with every pixel when an liquid crystal device 400 is driven. The respective pixels display either of a bright state or dark state when the pixels are irradiated with rays from a back light device 10. At this time, the absorption axis of a polarizer 9b is aligned to the direction of the first optically stable state. A motor M is driven and an analyzer 9a and the polarizer 9b are rotated by a prescribed angle and the absorption axis of the polarizer 9b is aligned to the direction of the second optically stable state when the prescribed time elapses in this state.  The signal from the information signal impression circuit to the liquid crystal panel P is changed over and all the optically stable states of the ferroelectric liquid crystals are changed. As a result, the dark state or bright state is continuously displayed. The optically stable states of the ferroelectric liquid crystals are properly changed over even in the case the bright state or the dark state is continuously displayed and, therefore, the monostabilization is prevented.
