摘要： A fabricating method for a system including a plurality of processing apparatuses connected to each other by an inter-apparatus transporter. The semiconductor waters are processed in the processing apparatuses and are transported to specified processing apparatuses in different time interval that are set to N times a unit time interval. Since the fabricating system includes processing apparatuses and an inter-apparatus transporter that are periodically controlled at time intervals related to a unit time, intervals related to a unit time, the scheduling of a plurality of works can be made efficiently to enhance the level of optimization, thus improving the productivity.

摘要： Disclosed is a fabricating system including a plurality of processing apparatuses connected to each other by means of an inter-apparatus transporter, wherein one group of semiconductor wafers are processed in processing apparatuses and other group of wafers are transported to specified processing apparatuses for a time interval from (To+T) to a time To; and another group of wafers are processed and the remaining group of wafers are transported for a time interval from (To+T) to (To+2T). Since processing apparatuses can receive at least one of works from the inter-apparatus transporter for a time interval T min, the distribution of works from the transporter to processing apparatuses is completed for the time interval T min. The transporter is emptied for each time interval T min, and works are unloaded to the emptied transporter, which makes easy the scheduling, control and management of the transporting of a plurality of works in the fabricating system. Moreover, since the fabricating system including processing apparatuses is periodically controlled at a cycle time T min, the scheduling of a plurality of works can be made easy, to enhance the level of optimization, thus improving the productivity.

摘要： In a bipolar device, such as transistor or a thyristor, the emitter layer or the anode layer is formed of two high-doped and low-doped layers, a semiconductor region for suppressing recombination comprising an identical semiconductor having an impurity density identical with that of the low-doped layer is present being in contact with a base layer or a gate layer and a surface passivation layer, and the width of the semiconductor region for suppressing recombination is defined equal with or longer than the diffusion length of the carrier. This provides, among other things, an effect of attaining reduction in the size of the bipolar transistor or improvement of the switching frequency of the thyristor without deteriorating the performance.

摘要： Conventionally, a MONOS type nonvolatile memory is fabricated by subjecting a silicon nitride film to ISSG oxidation to form a top silicon oxide film of ONO structure. If the ISSG oxidation conditions are severe, repeats of programming/erase operation cause increase of interface state density (Dit) and electron trap density. This does not provide a sufficient value of the on current, posing a problem in that the deterioration of charge trapping properties cannot be suppressed.For the solution to the problem, the silicon nitride film is oxidized by means of a high concentration ozone gas to form the top silicon oxide film.

摘要翻译： 通常，通过使氮化硅膜进行ISSG氧化来形成ONO结构的顶部氧化硅膜来制造MONOS型非易失性存储器。 如果ISSG氧化条件严重，编程/擦除操作的重复会导致界面态密度（Dit）和电子陷阱密度的增加。 这不能提供足够的导通电流值，这导致不能抑制电荷俘获特性的劣化的问题。 为了解决这个问题，氮化硅膜通过高浓度的臭氧气体被氧化，形成顶部氧化硅膜。

摘要： The method for promoting the size reduction, the performance improvement and the reliability improvement of a semiconductor device embedded with pressure sensor is provided. In a semiconductor device embedded with pressure sensor, a part of an uppermost wiring is used as a lower electrode of a pressure detecting unit. A part of a silicon oxide film formed on the lower electrode is a cavity. On a tungsten silicide film formed on the silicon oxide film, a silicon nitride film is formed. The silicon nitride film has a function to fill a hole or holes and suppress immersion of moisture from outside to the semiconductor device embedded with pressure sensor. A laminated film of the silicon nitride film and the tungsten silicide film forms a diaphragm of the pressure sensor.
