Title: Floor nozzle with reinforced jet flow
Inventor: KADOWAKI TAKESHI
IPC: A47L9/02
Filed: 1989-09-26
Abstract: PURPOSE:To efficiently enhance the dust collecting force by providing an air inflow port on the left and the right side walls of a floor nozzle, providing two bulkheads in the longitudinal direction, inclining and placing a brush between the front wall and the rear wall, and two bulkheads, and installing a suction port in the center of a passage between two bulkheads. CONSTITUTION:An airflow port 1 is provided on the left and the right side walls of a floor nozzle, and two bulkheads 4 are provided in the longitudinal direction of the floor nozzle. Between the front wall 2 and the rear wall 3 of the floor nozzle and two bulkheads 4, a brush 5 is inclined a little and placed in the longitudinal direction of the floor nozzle, and a suction port 6 is installed in the center of a passage between the bulkheads 4. In such a state, a jet flow is led in from the inflow port 1 provided on the side wall of the floor nozzle, and the jet flow is reinforced since the inflow area is small, and also, a speed of the jet flow does not decrease either since it passes through a limited passage, and it advances to the suction port 6 of the center part in a state that high dust collecting force is maintained. Even if a gap between the wall surface of the floor nozzle and the floor surface is small, sufficient action force can be secured, therefore, an effect for sweeping the floor surface by the lower part of the wall surface is enhanced. Also, the brush 5 provided obliquely generates an air brush effect since the jet flow passes through so as to intersect, and simultaneously, can prevent that dust adheres to the brush.

Abstract: PURPOSE:To decrease a shift of a line of a pattern caused by a rounding error by detecting a side in which the rounding error generated at the time of similar conversion scarcely occurs, setting this side as a reference of a line width control and executing the line width control. CONSTITUTION:An inflextion point on a border line of a pattern is extracted by an extracting means 111, and to a significant inflection point for a line width control, line width control information is added by an adding means 112. A line width control value generating means 113 generates a line width control value, a similar conversion means 114 multiplies a coordinate of the extracted inflection point by a similar conversion rate, and thereafter, a coordinate after the similar conversion obtained by rounding said result to an integer value and a rounding error caused by the similar conversion are generated. Subsequently, at the time of similar conversion of the pattern, a line width control means 115 determines a reference position for executing a line width control, based on said rounding error, and controls the line width by referring to line width control information and a line width control value. In such a way, a position shift of a vertical line and a horizontal line of the pattern generated by a rounding error can be decreased.

Title: Patterning method for silicon material layer
Inventor: YANAGIDA TOSHIHARU
IPC: H01L21/302
Filed: 1994-10-18
Abstract: PURPOSE: To provide a patterning process for silicon material layers, including trench etching to a single-crystal silicon substrate, wherein the selectivity of mask to resist is improved, wherein excellent anisotropy is obtained, and wherein less particle contamination is caused. CONSTITUTION: Plasma etching is performed using a gas mixture of a gas of inorganic oxide, such as COx , NOx and COx and a halogen gas. A sidewall protective film 5 formed during this plasma etching is composed mainly of decomposition products from a resist mask 4. The protective film has a less halogen content and has taken in polar groups, such as C-O bonds; therefore, it is excellent in resistance to ion bombardment and radical attack. A sulfuric compound may be used together to form the sidewall protective film by adding sulfur halide gas. Thus the enhanced quality of the sidewall protective film reduces the amount of its deposition, and makes possible anisotropic etching with reduced energy of incident ion. This prevents particle contamination and the reduction of resist masks.

Filed: 1987-10-06
Abstract: PURPOSE:To perform quick reading by discharging a bit line by a cell transistor TR to read a logic. CONSTITUTION:When input signals E1 and E2 are inputted, the inverse of an ITD signal goes to a low level to turn on a TR Q2, and a product term line (a) is charged up (a TR Q4 is turned off at this time). The output logic of the product term line (a) is settled by the input of input signals E1 and E2 at this time, and it is quickly settled because the product term line (a) is charged up. When the inverse of the ITD signal is returned to a high level, the TR Q2 is turned off and the TR Q4 is turned on, and therefore, the output logic is transmitted to an input line (e) of an OR array 2 through an inverter 3. A TR Q7 is turned off at this time. The quick operation is performed and the phase deviation of a pulse is eliminated because this circuit is dynamically operated by one kind of signal pulse ITD and the inverse of the ITD which are generated by the level change of input signals E1 and E2 or the like.

Thus, a difference between voltages VC1, VC2 being control voltages of the AGC amplifier gain 11 is changed and to change the AGC amplifier gain increasingly. Thus, an output FiloutX-FiloutY reaches a sett amplitude.
