Title: Mutual connection of electrode terminals
Inventor: TAKAHASHI MASANORI
IPC: G02F1/1345
Filed: 1990-07-23
Abstract: PURPOSE:To enable stable connection by charging conductive fine particles and scattering them and further, sticking them selectively on the terminals of electrodes with electrostatic forces. CONSTITUTION:Takeoff electrodes 4 formed on a glass substrate 3 are grounded. The takeoff electrodes 4 are covered with such an insulator that the opening parts of the insulator are provided only in its places just over the respective connection portions of the takeoff electrodes. Thereafter, conductive fine particles 1a are charged by a boxer-charger 2 or the device for charging fine particles, and are scattered over the takeoff electrodes 4. As charged conductive fine particles 1b approach the glass substrate 3, the charged conductive fine particles 1b in proximity to opening parts A of an insulator film 5 generate image forces of attractive ones between the respective lead electrode terminals 4 and themselves. Thereby, the comparatively more charged conductive fine particles 1b are stuck on the lead electrodes 4. Then, the insulator film 5 is removed, and the electrode pads of a semiconductor device are aligned with the lead electrodes 4 in the manner of a face down bonding. Thereafter, while compression-contacting, they are interconnected respectively by hardening an insulating adherent agent.

Title: Method and device for measuring electrical conductivity of solution
Inventor: FUREDERITSUKU KEE BUREIZU
IPC: G01R27/22
Filed: 1993-07-14
Abstract: PURPOSE: To measure the electric conductivity of a solution with high accuracy over a wide range by charging the parallel capacity of a measurement cell up to a maximum limit at every half-period of the bipolar drive signals of two electrodes, and minimizing a measurement error generated due to the electric conductivity of the cells. CONSTITUTION: One of the feedback resistors Rf of the resistance network 24 of a current-voltage conversion circuit is selected with a range selector switch 26 and set at a low value. Then, the parallel capacity CP of a measurement cell 20 across both of electrodes 14 and 16 is fully charged during an initial charging period at every half-period of bipolar rectangular drive signals VDRIVE. When the resistor Rf is selected to obtain the optimum gain of an operational amplifier 22 during the measurement of the electric conductivity of a solution within the range of maximum conductivity, the final value of cell current ICELL is obtained during a charging period ending relatively early within each half-period, due to the capacity CP. Thus, when the current ICELL is sampled during a sampling period near the termination of each half-period of the signal VDRIVE, distortion due to the capacity CP becomes minimum, thereby improving measurement accuracy.
