Title: Semiconductor element and its manufacture, and treatment method after dry etching
Inventor: YABUTA TETSUSHI
IPC: H01L21/336
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To reduce the OFF-state current of a semiconductor element and to enhance its electric characteristic by a method wherein, after an etching operation, the number of defect levels generated in the semiconductor element is reduced. SOLUTION: When a post-treatment is executed after a dry etching operation, a plasma surface treatment is executed by using a gas whose reactivity to a substrate 101 and a device 102 is low such as, e.g. N2 , Ar, He or the like, and an etching gas or a reaction product element which is stuck to the substrate 101 and the device 102 is removed. Thereby, the plasma surface treatment can be continued through an apparatus which performs a dry etching operation, and it is not required to especially install an apparatus which is used to remove the etching gas or the reaction product element which is stuck to the substrate 101 and the device 102. Consequently, after the etching treatment, the etching gas or the reaction product element can be removed by executing a plasma surface treatment by the gas whose reactivity to the substrate 101 and the device 102 is low, and the reliability of the device 102 can be enhanced.

IPC: B22D43/00
Filed: 1991-07-05
Abstract: PURPOSE:To prevent entrapping of gas by arranging baffles for preventing the development of rotating vortex flow in inner wall in a holding vessel for temporarily storing a solid-liquid coexisting metal while keeping uniformity and fluidity of the metal under solid-liquid coexisting condition by stirring. CONSTITUTION:At the time of stirring the solid-liquid coexisting metal in the ordinary cylindrical vessel, in the case of using simple paddle type stirrer 1, fluidity of the solid-liquid coexisting fluid becomes circular flow having a little vertical movement according to the stirring. Therefore, the higher solid phase ratio is, the more deposit of solid phase particles are developed at bottom wall of the vessel, and the uniformity is obstructed. In the case of executing the stirring in the vessel fitting the baffles 2 for preventing circular fluidity on the side wall of the vessel, as the vertical flow is developed in the bath, the deposit of solid phase on the bottom wall of vessel according to stirring, is prevented. By this method, the metal under solid-liquid coexisting condition can be held with weak stirring force while maintaining the uniformity and the fluidity without disadvantage of developing the entrapping of gas.

Title: Noise eliminating device
Inventor: NAKAYAMA ISAO
IPC: H04N5/21
Filed: 1994-07-22
Abstract: PURPOSE:To suppress the gain variance of a chroma signal and to reduce the circuit scale by providing an LPF which can vary the cut-off frequency by a control current and then switching the control current to the prescribed set value in response to the ON/OFF switching state set for removal of noises. CONSTITUTION:A subtractor 5 subtracts the output of a 1/N device 6 from the output of a voltage/current converter 4 and inputs this subtracted output to the right contact of a switch 3. The switch 3 selects the output of the converter 4 of the left contact and the output of the subtractor 5 of the right contact when an NR (noise removal) signal is turned off and on respectively. Meanwhile the mutual conductance of an LPF 1 of 4.5MHz is controlled and its cut-off frequency is set at 4.5MHz when a control current is controlled by the control voltage in an OFF state of the NR signal. If the N of the device 6 is set at 15 under such conditions, the cut-off frequency of the LPF 1 is set at 4.2MHz in an ON state of the signal NR. Thus it is possible to reduce the circuit scale and to suppress the gain variance of a chroma signal in an ON/ OFF switching state of the NR signal in order to improve the S/N.
