    • The invention relates to a method for producing a multi-layer structure which comprises a buried layer and is used for electronic, optic and optoelectronic engineering consisting in a) forming the layers of the structure including the buried layer, and in b) chemically treating said structure using chemical species for substantially engraving the buried layer material. The stage a) consists in forming, a buried protective layer which is arranged on the buried layer and made of a material selected such that it is sufficiently resistant to the chemical attack of the treating chemical species used at the stage b), thereby blocking possible access of said chemical species to the buried layer therethrough. The use of said method for producing structure for electronic, optic and optoelectronic engineering is also disclosed.
    • 本发明涉及一种用于制造多层结构的方法,其包括埋层并用于电子,光学和光电子工程,其包括:a)形成包括该掩埋层的结构层,以及b)化学处理所述 使用化学物质的结构基本上雕刻掩埋层材料。 阶段a)包括形成埋置的保护层,该掩埋保护层设置在掩埋层上并且由选择的材料制成,使得其充分抵抗在阶段b)处使用的处理化学物质的化学侵蚀,从而阻断可能 所述化学物质通过其进入掩埋层。 还公开了用于生产电子,光学和光电子工程结构的所述方法的使用。
