The number of rewrites for memory cells is to be increased, and the reliability of data reading to be substantially improved. Where data in memory cells are to be erased, the switching of an erase voltage to be applied to the control gate of each memory cell, while switching from one to another of voltages of any different levels, as the control gate voltage (=soft erase voltage) is accomplished according to the quantity of electric charges accumulated at the floating gate of each memory cell so as to keep substantially constant the voltage applied to the tunnel film of the memory cell. Upon acceptance of an erase command, a CPU supplies a control signal to a decoder, and on the basis of the resultant decode signal an erase voltage switching circuit generates a soft erase voltage of a certain level. After that, while switching from one to another of soft erase voltages differing in level, data in the memory cell are erased. Upon completion of erasing data in the memory cell, erase verification is carried out.

When a detecting complex event condition expression is changed, a rule comparing unit compares the complex event condition expressions before and after the change. The changed portion identifying unit identifies the changed portion based on the comparison result, and the parallel operating unit operates the complex event condition expressions before and after the change in parallel for the detecting complex event condition expression including the identified changed portion. In this manner, the complex event processing apparatus disclosed therein can dynamically change a detecting complex event condition expression used in the complex event processing.

In order to provide an electronic device permitting a reduction in size or an expansion of its internal space while maintaining its mechanical strength, a structure having mechanical strength is integrally formed with hinges for fitting a lid-shaped display unit to a box-shaped body and a carrying handle projecting outward from the box-shaped body.
摘要:
In order to eliminate erroneous reading of data by preventing noise which might otherwise be transmitted at the data read time through parasitic capacitance in the data lines to other data lines, switches (Qt1 and Qt1′) are interposed between a sense amplifier (SA) for amplifying the potential of a data line (DL) and the data line, and the sense amplifier is fed with an operating voltage after the potential of the data line is transmitted to the sense amplifier, and the switch is turned off.
摘要:
Disclosed is a method for the formation of a silica-based coating film of a relatively large thickness in the manufacturing process of semiconductor devices and liquid crystal display panels by repeating the sequence consisting of coating of the surface with a coating solution containing a partial hydrolysis-condensation product of a trialkoxy silane compound followed by drying until a desired overall thickness of the coating film is obtained prior to a final baking treatment at 350 to 500.degree. C . The invention provides an improvement obtained by an ultraviolet irradiation treatment of the coating film intervening between a sequence of coating and drying and the next sequence of coating and drying so that the adhesion between the coating layers formed by repeating the sequence of coating and drying can be improved along with an advantage of absence of pinholes in the coating film.
摘要:
Proposed is a coating solution for the formation of a silica-based coating film on the surface of a substrate used in the manufacturing process of semiconductor devices as well as a method for the coating solution, which exhibits excellent storage stability without gelation and is capable of forming a silica-based coating film free from the troubles due to evolution of gases such as crack formation even when the coating film has a relatively large thickness. The coating solution is prepared by the hydrolysis reaction of a trialkoxy silane such as triethoxy silane dissolved in propyleneglycol dimethyl ether in a specified concentration with addition of a specified amount of water followed by removal of the alcohol formed by the hydrolysis reaction of the trialkoxy silane by distillation to such an extent that the content of the alcohol in the coating solution does not exceed 10% by weight or, preferably, 3% by weight.
