Title: Formation of silicon oxide film
Inventor: KAMIMURA KENICHI
IPC: H01L21/316
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To form a gate oxide film having good electrical characteristics by a method wherein a silicon oxide film is previously formed on a silicon substrate in an oxidizing aqueous solution and thereafter, a silicon oxide film is further formed on the silicon substrate by a thermal oxidation. SOLUTION: In a method of forming this oxide film, a silicon substrate removed a natural oxide film, a contaminant and the like from thereon by a normal cleaning method is dipped in an oxidizing solution, such as the mixed solution of ammonia and water hydrogen peroxide, the mixed solution of a hydrochloric acid and water hydrogen peroxide, a hydrogen peroxide aqueous solution, a nitric acid solution and an ozone solution, to form previously a very thin silicon oxide film on the silicon substrate and thereafter, a thermal oxidation is performed to form a silicon oxide film on the silicon substrate. In the case where the substrate is heated up in high-purity nitrogen gas or inert gas at the time of a dry oxidation, recesses and projections, which are generated in and on the surface of the silicon oxide film, are inhibited.  Thereby, with the gate breakdown strength of an MOS device enhanced, an increase in the mass production of the MOS device can be executed in small equipment investments.

Filed: 1982-05-21
Abstract: PURPOSE:To set the current amplification degree at nearly an ideal level even in a region where the current amplification factor is small, by adding a transistor(TR) to a conventional current mirror circuit. CONSTITUTION:The total current of base currents of TRs Q21 and Q22 flows to the emitter of a TRQ23, and the base current of the TRQ23 flows to the collector of the TRQ21.

These TRs Q24 and Q25 form a current mirror circuit, and the current flowed to the common joint of the emitters of TRs Q24 and Q25 is branched to the earth side and the collector side of the TRQ22. The current amplification factor A is obtained as shown in an equation from the ratio between an output current I2 and an input current I1, where alpha show the current amplification factor of the base earths of the TRs Q21 and Q22, (a) is the emitter area ratio of the TRQ22 to the TRQ21, and (m) is the emitter area ratio of the TRQ25 to the TRQ24. In addition, Km=m/(1+m) is satisfied to obtain the relation between the current amplification factor and the current amplification degree with the Km set as a parameter. Thus, the degree of improvement for said relation is confirmed.

IPC: B03C3/66
Filed: 1980-06-26
Abstract: PURPOSE: To avoid the rescattering of dust by a flow of ions by supplying two or more different discharge currents to plural discharge electrodes.  
     CONSTITUTION: Discharge electrodes 2 and 3 receiving different discharge currents are provided to a dust collecting electrode 1, where a discharge wire having a large diameter and acute edges is used in order to weaken a flow of ions. When the discharge electrode 2 is placed on the upstream side in relation to the flow of gas and also the discharge electrode 3 is placed on the downstream side, dust is sufficiently charged electrically while jumping because of strong ion flow beneath the discharge electrode 2. When reaching the underneath of the discharge electrode 3, the dust is attracted by the dust collecting electrode 1 without scattering because the ion flow becomes strong, and then again charged sufficiently on the discharge electrode 2 having large discharge current because the charge of the dust is fully released. The dust is then collected beneath the discharge electrode 3 having a small ion flow.
