摘要： A method for producing a filter includes the steps of providing a blank of etchable semiconductor material having a first side and a second side and affixing a holding element to the blank. The holding element is chemically resistant to an etching solution. A current source is connected to the blank and at least one of the first and second sides of the blank is illuminated with light. The holding element and the blank are immersed in the etching solution until the first side of the blank is wetted so that the first side is etched electrochemically. The holding element is affixed to the blank such that contact areas between the holding element and the blank remain free of the etching solution.

摘要： A method is proposed for acquiring a service sold over a data network (20) against presentation of a transaction medium (2). The service is ordered by a user (1) by a user end system (10) from a service provider (40). The latter calls in a clearing center (30) which enters into a data exchange with the transaction medium (2) to call for therefrom a necessary contribution in the form of certain data assumed for acquisition of the service. The ordering process and the data exchange with the transaction medium (2) for calling for the contribution are linked via an identifier (KM) associated with the transaction medium (2), the identifier being determined by the user end system (10) and used to secure the ordering process and the call for the contribution.
摘要翻译：提出了一种用于获取通过数据网络（20）销售的服务以反对交易介质（2）的呈现的方法。服务由用户（1）由用户端系统（10）从服务提供商（40）排序。后者呼叫在与交易媒体（2）进行数据交换的结算中心（30），以便以为购买服务而假设的某些数据的形式向其提出必要的贡献。通过与交易媒体（2）相关联的标识符（KM）链接与用于呼叫贡献的交易媒体（2）的订购过程和数据交换，该标识符由用户端系统（10）确定并使用以确保订购过程和要求的贡献。
