Inventor: LEE DONG YUN
IPC: G06F1/12
Filed: 1999-10-13
Abstract: PURPOSE: There is provided a synchronizing circuit for minimizing a phase difference between a reference clock signal and an inner clock signal, and a time/digital converter used for minimizing the phase difference. CONSTITUTION: A time/digital converter(211) includes first and second delay chains for delaying one of two input signals by a predetermined time interval. This time/digital converter also has first and second phase comparators for comparing the phase of the delayed signal with that of the other signal to generate a digital signal. A synchronizing loop converts a phase difference between a feedback signal and an inner clock signal into a delay control signal group using the time/digital converter. The delay control signal group controls the amount of delay of a delay reflecting circuit(207) to minimize the phase difference between the feedback signal and the inner clock signal rapidly.

Abstract: An electrostatic adhesion tester for thin film conductors. In one embodiment, a device is provided for testing the adhesion strength of a thin film conductor that has been formed upon a substrate. The device includes an adhesion tester that is primarily comprised of a conducting portion. The conducting portion is applied to the thin film conductor so that it does not physically contact the thin film conductor, but leaves a small space therebetween. A power supply may further be provided for coupling to either the adhesion tester, the thin film conductor, or both in order to create a potential difference between the conducting portion and the thin film conductor. The potential difference creates an electric field between the conducting portion and the thin film conductor that induces stress in the thin film conductor. A measuring device may also be provided for coupling to the adhesion tester and the thin film conductor in order to measure an electrical parameter of the electric field, which is indicative of the adhesion strength.
