Title: Method for forming capacitor of semiconductor
Inventor: LEE GI JEONG
IPC: H01L27/10
Filed: 1998-12-30
Abstract: PURPOSE: A method for forming a capacitor of a semiconductor is to achieve a desired capacitance for high integration of semiconductor. CONSTITUTION: A storage node is connected to a semiconductor substrate(11) through a contact hole(15). A surface of the storage node is nitrified to prevent an oxide deteriorating the permitivity of the surface of the storage node. After that, A (Ta2))x-1 - (TiO2)x thin layer(21) is formed on the surface and a plate electrode is formed on the dielectric layer(21). The (Ta2))x-1 - (TiO2)x thin layer(21) has a lattice structure of tetragonal system and good anti-leakage current and high dielectric breakdown voltage. Thereby, achieving a desired capacitance for high integration of semiconductor.

CONSTITUTION: The atmosphere analyzer includes; at least 2 supply sources(SI, S2,...) of beginning gases to be analyzed; at least 2 divergence pipes(LP1, LP2,...) connected with one of the supply sources in upper part, connected with each flow orient factor(VI, V2,...) in lower part; at least 2 emit pipes(LE1, LE2,...) connected with one of the flow orient factors in upper part, connected with an emit or store point(E1, E2,...); at least 2 second divergence pipes(LS1, LS2,...) connected with one of the flow orient factors in upper part, connected with a collect point(R) in lower part; a third pipe(LT) connected with the collection point in upper part, connected with the emit or store point; at least 1 analyze pipe(LAi) connected with the third pipe in upper part separately, connected with at least 1 analyzer. The flow orient factor can decide moving direction of the sample from the supply sources to each emit pipe or collect point.

Abstract: PURPOSE: A bellows device for a semiconductor vacuum equipment is provided to improve the working ability of the semiconductor vacuum equipment by preventing the leakage of the vacuum. CONSTITUTION: A distance between corrugated portions of the bellows at both sides(11) of the bellows is larger than the other portion. The both sides(11) of the bellows are fabricated by using thicker panel as compared with a center portion(13) of the bellows so as to reduce the flexibility at the both sides(11) of the bellows. Accordingly, the corrugated portions of the center portion(13) of the bellows have a large transforming range. In addition, the both sides(11) of the bellows are fabricated by using material having a high mechanical strength.

Abstract: PURPOSE: Provided is a brush spring structure of a motor for a vacuum cleaner, which is characterized in that an electric current flows from a stator tap to the brush through the spring not electric wires. CONSTITUTION: The brush spring structure of the motor for the vacuum cleaner comprises the stator tap(12a), the brush(14c), a brush holder(14), the spring(20) connected between the stator tap(12a) and the brush(14c), wherein the electric current flows directly from the stator tap(12a) to the brush(14c) of the brush holder(14), and a proper load is added to a commutator(15).

Abstract: PURPOSE: An aqueous detergent having improved emulsifying capacity by suitably mixing several sorts of nonionic and ionic surfactants using characteristics of a microemulsion and forming a microemulsion by adding terpene oil thereto is provided, which can effectively clean oil materials on the surface of an object of cleaning such as cutting lubricant, rolling oil or the like. CONSTITUTION: The aqueous detergent as a substitute detergent for CFC-113 and 1,1,1 TCE detergents is prepared by microemulsifying glyceryl stearate and Tween-80 as a nonionic surfactant, dioctyl sodium sulfosuccinate (A-OT) as an ionic surfactant, oleic acid and D-limonene as terpene oil. The detergent does not have a risk of ozone layer destruction, is harmless and environmentally favorable and has excellent detergency.
