摘要:
A testing method is provided for a semiconductor device which includes a control terminal and a pair of main terminals wherein one of the main terminals is isolated from the outside by a dielectric. First, a voltage which changes with time is applied to the isolated main terminal through the dielectric. A control signal which controls conduction and non-conduction of the semiconductor device is the applied to the control terminal. Following this, the test is made by detecting a displacement current flowing through at least one of the two main terminals and the control terminal.

A liquid crystal display device has a plurality of pixel elements, the optical transmissivity of which is varied by suitable electrical signals. The liquid crystal display device has electrodes which apply electric fields to a liquid crystal layer, the electric fields having components in a direction generally parallel to the liquid crystal layer. Each pixel element has at least one pixel electrode which extends in a common direction as a signal electrode and common electrodes which extend over several pixel elements. The common electrodes may be on the same side of the liquid crystal layer as the pixel and signal electrodes, or they may be on opposite sides. Each pixel may have two pixel electrodes with the signal electrode disposed therebetween, and there are then a pair of common electrodes with the pixel electrodes therebetween. The common electrodes may be common to adjacent pixel elements. The pixel electrodes and the common electrodes may be separated by an insulating film.

In a liquid crystal display substrate in which the pixel electrode is applied with a voltage through the drain and source of a thin-film transistor (TFT) that conducts by a voltage applied to the TFT gate electrode, this gate electrode and a busline connected to the gate electrode are formed as a multi-layered structure consisting of a gate layer and at least two layers of a gate insulation film and an amorphous silicon film. The multi-layered structure is formed by etching through a single mask.

In a digital wireless communication system, a first unit transmits a digitally encoded signal to a second unit in a plurality of non-contiguous time slots. Within each time slot, the digitally encoded signal has a synchronization signal portion followed by a data signal portion. The second unit has an antenna to receive the synchronization signal portion of the digitally encoded signal. The second unit also has a clock to generate a clock signal at a first rate having a sampling phase. An analog to digital converter receives the clock signal and the synchronization signal and samples the synchronization signal at the first rate to generate a first plurality of symbols. An interpolator receives the first plurality of symbols and interpolates the first plurality of symbols to generate a second plurality of symbols at a second rate. The second rate is a multiple of the first rate. A match filter receives the second plurality of symbols and compares the second plurality symbol of symbols to a stored plurality of symbols to generate an error signal. The sampling phase of the clock signal is altered in response to the error signal, after to the receipt of the synchronization signal.
