Then, an etch stop layer is formed on the entire surface of the resultant structure having the thermal oxide layer to an appropriate thickness such that the between the gate electrodes is not buried. Then, a first interlayer dielectric (ILD) film covering the space between the gate electrodes and the top of the gate electrodes is formed, and the first ILD film is then patterned to form a landing pad hole which exposes the spacer and the etch stop layer. Then, the etch stop layer and the thermal oxide layer are removed to expose the surface of the semiconductor substrate, and the landing pad hole is then filled with a conductive material to form landing pads.

Granted: 2000-03-21
Abstract: The present invention disclose a display device in which each pixel comprises a plurality of luminous components with different luminous intensity. The gray scale is represented by controlling the ON/OFF of each luminous components. The digital signals are transmitted to each pixel and the pixels are controlled by the thin film transistors connected to each luminous components in series. The luminous intensity of each luminous component is the geometric progressions of a common ratio of 2. The ON resistance of thin film transistors is smaller than the ON resistance of luminous components and the OFF resistance of thin film transistor is larger than the OFF resistance of luminous components. Therefore, it can reduce the nonuniformity of luminous intensity of luminous components caused by the nonuniformity in the conductivity of transistors so as to improve the display quality.

Title: Valve operating system in internal combustion engine
Inventor: NEMOTO HIROTOMI
IPC: F01L1/12
Filed: 1998-10-28
Granted: 1999-09-01
Abstract: An actuator is connected to one of components forming a power transmitting device capable of transmitting a power provided by a valve operating cam provided on a cam shaft, so that the actuator can drive an engine valve in a lift amount which is obtained by addition of a lift amount of the engine valve based on a cam profile of the valve operating cam and a lift amount of the engine valve based on the operation of the actuator. Thus, a portion of the lift amount of the engine valve is borne by the valve operating cam, whereby a valve-opening power borne by the actuator can be reduced, as compared with a system designed so that the engine valve is driven by only the actuator only. The amount of electric power consumed by the actuator can be smaller.
