    Abstract: Very fine circuit structures in microelectronics are produced by first applying a thin metal oxide layer uniformly over an entire surface of a layer to be etched, then applying a resist layer uniformly over the entire metal oxide layer and structuring such oxide layer by ion-beam etching and, utilizing the structured oxide layer as a mask, performing a dry-etching with an ion beam of the metal layer lying thereunder so as to attain structures having very unfavorable resist height to etching depth ratios.

    Abstract: A method for making large scale integrated circuits on a disklike semiconductor substrate includes grinding a disk thin enough to be able to be sawn apart into individual chips. A damage zone caused by the grinding on a back side of the wafer is removed by etching while protecting a front side of the wafer, prior to sawing. The etching is carried out in the form of a microwave or high-frequency-excited downstream plasma etching process using fluorine compounds in an etching gas.

    Abstract: A carrier has a surface with a mask layer thereon. An irradiation-sensitive layer on the mask layer is exposed and developed to form a first exposure structure. The first exposure structure is used as an etching mask while the mask layer is etched. The first exposure structure is subsequently removed. A second irradiation-sensitive layer is applied to the mask layer and the carrier. The second irradiation-sensitive layer is exposed with a first exposure dose and a second exposure dose. The second irradiation-sensitive layer is subsequently developed to form a second exposure structure with a first and second exposure structure thickness. The carrier is etched down to a first etching depth in the region of the first exposure structure thickness and down to a second etching depth in the region of the second exposure structure thickness. The first etching depth is larger than the second etching depth.
