Abstract: PROBLEM TO BE SOLVED: To provide a working method for single crystal alumina whereby objective deep unevenness or the like can be formed on the surface of single crystal alumina.
SOLUTION: The working method comprises the step of forming an etching mask comprising a nitrogen-containing compound on the surface of single crystal alumina and the step of subjecting the single crystal alumina to reactive ion etching with a plasma containing boron and chlorine by using the etching mask.

Abstract: (57)【要約】 本発明は、プラズマ(14)を用いた、基板(10)、特に構造化されたシリコン基板の有利には異方性エッチングのための装置である。 この場合プラズマは、プラズマ生成源(13)を用いて形成され、このプラズマ生成源には高周波電力の印加のために高周波発生器(17)が接続されている。 高周波生成源にはさらに、プラズマ生成源(13)に印加する高周波電力に周期的な変化を生じさせる第1の手段が接続されている。 その他にもそのつどの高周波電力の作用として変化するプラズマ発生源(13)のインピーダンスに前記高周波発生器(17)の出力インピーダンスを整合させる第2の手段が設けられている。 前記異方性エッチング方法は、交互に別個のエッチングステップと重合ステップにおいて実施され、エッチングステップ期間中には少なくとも時折、デポジションステップ期間の時よりも高い5000Wまでの高周波電力がパルス生成源に印加される。

Abstract: PROBLEM TO BE SOLVED: To remove non-crystalline carbon. SOLUTION: A substrate 1, in which crystalline carbon is formed on a catalytic metal, is placed inside of a reaction tube 2 equipped with a vacuum pump 3 for exhaust. Oxygen is supplied from a gas source 4 into the reaction tube 2, and a mixed gas is plasma gasified by a microwave from a microwave generator 5. Non-crystalline carbon, formed on the substrate 1 during crystalline carbon is formed, is made ashing by plasma gasified oxygen and removed selectively.

Abstract: PROBLEM TO BE SOLVED: To detect a crystal defect affecting the oxide film breakdown voltage and secular dielectric breakdown characteristics of a silicon wafer, to simplify a measuring method, to improve and simplify evaluating method for oxide film breakdown strength and secular dielectric breakdown characteristics, and to significantly shorten a measurement time while a cost is reduced. SOLUTION: This is related to a crystal defect detecting method for a wafer wherein a thermal process is performed for forming a thermally oxidized film on the surface of a silicon wafer before thermally treated in the atmosphere containing hydrogen, so that the crystal defect in the silicon wafer is generated as a pit on the thermally oxidized film. In an oxide film breakdown voltage characteristics evaluating method for a silicon wafer, these are measured with a particle counter and the oxide film breakdown voltage characteristics of the silicon wafer is evaluated from the total number of pits of 0.15 μm or larger in size.
