Abstract: PURPOSE: A fluid supply apparatus for supplying a nitrogen gas into a cassette chamber containing wafers is provided to reduce particles accumulated on the wafers from the nitrogen gas. CONSTITUTION: The fluid supply apparatus(200) includes a guide pipe(210) for supplying the nitrogen gas into the cassette chamber(230) from a nitrogen supply source(260) so as to make an atmospheric pressure in the chamber(230). The chamber(230) accommodates a cassette(240) holding the wafers(220) therein. The guide pipe(210) is extended to the inside of the chamber(230) through a hole(232) and equipped with a diffusion outlet(245) in the chamber(230). The diffusion outlet(245) has a greater diameter than the guide pipe(210), so that the nitrogen gas flowing in the guide pipe(210) may slow down in the diffusion outlet(245). Therefore, the nitrogen gas can hardly run direct to the wafers(220). In addition, a mesh plate(250) is equipped on the front of the diffusion outlet(245) to scatter the nitrogen gas and to filter out the particles from the nitrogen gas.

Abstract: PURPOSE: A method for forming a gate oxide layer in a metal-oxide semiconductor field effect transistor is provided to prevent the creation of an undesirable pitting during an etch of a gate electrode and further to prevent the penetration of boron in a dual gate structure. CONSTITUTION: The first gate oxide layer is formed on a semiconductor substrate(100), and nitrogen ions are implanted into a specific portion of the substrate(100) through a photoresist pattern exposing the portion. The photoresist pattern and the first gate oxide layer are then removed. Thereafter, the second gate oxide layer(108) such as an oxynitride layer is formed on the exposed substrate(100) by thermal oxidation. In particular, the second gate oxide layer(108) is little grown at the portion where nitrogen ions are implanted, but sufficiently grown at the other portion. Therefore, the second gate oxide layer(108) has a dual thickness. A conductive layer is then deposited on the second gate oxide layer(108) and patterned to form the gate electrode without creating the conventional pitting.

Abstract: PURPOSE: A method for transmitting real time periodic and non-periodic data in a control communication network of a distributed control system is provided to secure transmissions of the real time non-periodic data and transmissions of hard real time periodic data, by using one communication network, and to secure transmissions of soft real time periodic data. CONSTITUTION: A control communication network of a distributed control system sets up a THT(Token Hold Time) and a TTRT(Target Token Rotation Time), and assigns transmission priorities. The control communication network decides whether data transmissions are secured, and implements a communication network for transmitting real time non-periodic data and real time periodic data. If a TTRT1 is smaller than a deadline(d11) of the real time non-periodic data and is smaller than a minimum period(d12) among hard real time periodic data, the calculated TTRT1 is used. If the TTRT1 is bigger than the 'd11' of the real time non-periodic data or bigger than a minimum period(d12), the control communication network sets up a value calculated by subtracting a communication band relating to non-periodic non-real time data from the TTRT1, as a TTRT2.

Abstract: A dismantlable, multi-story facade scaffold is formed of at least four vertical support elements and floor plates and railing elements which are mounted thereto. An additional scaffold story is erected by coupling an additional vertical support element to an already existing one and pivotally attaching one end of a railing element thereto at a location above where the floor plate for the next story will be placed. The other end of that railing element is pivotally attached to another vertical support element. This other vertical support element is then raised, thereby pivotally moving the rail element relative to the respective vertical support element until the rail element is in a horizontal position and the vertical support element is in the vertical position. The other vertical support element is now attached to the upper end of a corresponding vertical support of the lower scaffold story. Thereafter the floor plate for the additional scaffold story is installed so that a worker stepping on the floor plate of the higher story is protected from the very beginning against falling off. The connections between the ends of the railing and the respective vertical support elements are disengageable when they are in relatively inclined positions and become locked when the railing is perpendicular to the support elements. The scaffold is dismantled by reversing this procedure.
