Inventor: HA JEONG HYEOK
IPC: H01L21/66
Filed: 1999-12-31
Abstract: PURPOSE: A method of sorting a wafer is to move the wafer between slots without using sorting equipment in a critical dimension-scanning electron microscope, thereby obtaining an easy operation and reducing the manufacturing cost. CONSTITUTION: A control portion displays the initial state at which a wafer is inserted into a slot. A wafer cassette contains the slots to the number of 25. The wafer is inserted into the 4th slot, the 7th slot, the 8th slot and the 15th slot. The control portion determines whether a key signal is applied or not. The key signal is used to command movement of a wafer from a key input portion. If the key signal which commands to move respectively the wafer inserted into the 14th slot and the 15th slot toward the 10th slot and 2nd slot is applied, the control portion controls a notch arrangement to move the wafer toward the appointed slot. Upon completion of movement of the wafer, the state of the wafer is displayed.

Abstract: PURPOSE: A method for forming a selective epitaxial layer is to previously remove oxide on a wafer substrate by flowing a washing gas under a certain condition, without providing a selective epitaxial growth(SEG) cleaning apparatus with an additional provision. CONSTITUTION: Before an SEG process is carried out, a lower structure of a substrate is cleaned in-situ using NF3 or SF6 gas. At that time, a pressure of the NF3 or SF6 gas belongs to a range from 0.001 to 760 torr, and the cleaning process is carried out under a condition that a temperature is within 500 to 1200 deg.C. Upon cleaning the lower structure, any one of inert gas consisting of N2, Ar and He is mixed with the NF3 or SF6 gas at a mixing ratio of 1 : 1 to 100. If the lower structure is cleaned using the NF3 or SF6 gas, an etching reaction regarding to silicon oxide is highly produced relative to silicon.

Abstract: A decelerator device for obtains constant and maximal decelerating power whatever the engine speed, by controlling the pressure of the gases upstream of the valve by balancing the efforts at the actuator cylinder rod. The decelerator device (1) includes a balancing device (25) incorporated in the actuator cylinder (9), cylinder rod (12) dissociated from the piston (11) and a calibrated spring member (26) mounted between them. When the valve (7) is closed and, based on a counter-pressure predetermined by the spring member calibration, the actuator rod (12) moves back by stroke C' which causes the valve (7) to open by an angle prop generating a leakage of the exhaust gases. Beyond the. threshold, the valve (7) reopening angle varies according the exhaust gas pressure thereby ensuring a constant and maximal counter-pressure whatever the engine speed. The invention is applicable to combustion engines and in particular to industrial vehicles.
