摘要:
The present invention relates to a planographic printing plate employed in the field of offset printing, and more particularly, to a preparation method for a printing plate employing a conventional planographic printing original plate with a novel light source. In this method, an image is formed to a planographic printing original plate, in which at least one photosensitive layer sensitive in the region of 300 nm˜450 nm is provided on a substrate, by scan irradiating the plate with high density energy light in the form of the image, and then performing wet development and a post-treatment. This preparation method for the printing plate is characterized in that the output wavelength of the high density energy light is within the range of 300 nm or more, but less than 370 nm, and the high density energy light is high density energy light of the second or third harmonic obtained from a solid-state semiconductor or a solid-state exited by semiconductor. By means of this method, it is possible for an image to be directly drawn stably and at low cost to a conventional planographic printing original plate that was manufactured for an application with active rays, by employing high density energy light that is scan irradiated according to digital information. As a result, high resolution images can be reproduced easily.

This newly invented film possesses good blocking resistance and excellent adhesiveness with print ink, laminate, and other coating mixtures, and is especially suitable for boiling sterilization, retort sterilization, and packaging of liquids.

An inscribed character is recognized with a device including a memory for storing signals representing the shapes of plural inscribed characters, a sensor for the shapes of inscribed characters, a comparator for the stored signals and signals from the sensor, and a display. The comparator compares a signal representing the sensed shape of the inscribed character and the stored signals representing the shapes of plural characters likely to be inscribed to derive signals representing plural selected candidate characters similar in shape to the inscribed character. In response to the signals representing plural selected candidate characters similar in shape to the inscribed character the plural candidate characters are displayed on a first region of the display abutting a second region where there is a representation of the inscribed character. One of the displayed plural candidate characters that is the intended character for the inscribed character is selected by an operator pressing a stylus against the intended character. A signal indicative of which of the displayed candidate character is the selected character is derived and causes the selected character to replace the inscribed character.

A semiconductor integrated circuit device having a switching MISFET, and a capacitor element formed over the semiconductor substrate, such as a DRAM, is disclosed. In a first aspect of the present invention, the impurity concentration of the semiconductor region of the switching MISFET to which the capacitor element is connected is less than the impurity concentration of semiconductor regions of MISFETs of peripheral circuitry. In a second aspect, the Y-select signal line overlaps the lower electrode layer of the capacitor element. In a third aspect, a potential barrier layer, provided at least under the semiconductor region of the switching MISFET to which the capacitor element is connected, is formed by diffusion of an impurity for a channel stopper region. In a fourth aspect, the dielectric film of the capacitor element is co-extensive with the capacitor electrode layer over it. In a fifth aspect, the capacitor dielectric film is a silicon nitride film having a silicon oxide layer thereon, the silicon oxide layer being formed by oxidizing a surface layer of the silicon nitride under high pressure. In sixth and seventh aspects, wiring is provided. In the sixth aspect, an aluminum wiring layer and a protective (and/or barrier) layer are formed by sputtering in the same vacuum sputtering chamber without breaking the vacuum between forming the layers; in the seventh aspect, a refractory metal, or a refractory metal silicide QSI.sub.x, where Q is a refractory metal and 0
摘要:
A semiconductor integrated circuit device having first and second field-effect transistors, wherein the gate electrode of the first field-effect transistor is defined by a first-level conductor layer, while a wiring which is connected to the source or drain region of the first field-effect transistor is defined by a second-level conductor layer, and the gate electrode of the second field-effect transistor is defined by a combination of the first- and second-level conductor layers which are stacked one upon the other. Further, the respective gate electrodes of the first and second field-effect transistors are formed through respective gate insulator films which are formed on the principal surface of a semiconductor substrate in the same manufacturing step. By virtue of the above-described means, it is possible to reduce the area required for connection between the source or drain region of the first field-effect transistor and the wiring and to thereby increase the scale of integration of the device. In addition, it is possible to lower the resistance of the gate electrode of the second field-effect transistor and to thereby increase the operating speed of the device. Since the first and second field-effect transistors can be formed on a semiconductor substrate having no damage generated thereto, it is possible to increase the dielectric strength of the gate insulator film and to thereby improve the electrical reliability of the device.
