    摘要: A photolithographic mask having half tone main features and perpendicular half tone assist features. One embodiment provides for the exposure of radiation-sensitive resist layers on semiconductor substrates. The mask has at least one radiation-transmissive substrate and at least one half-tone layer. The half-tone layer is used to provide main features, the main features being formed in such a way that the pattern formed by the main features is transferred into the resist layer when irradiated, and the half-tone layer is also used to provide assist features, the assist features being formed substantially perpendicular to the main features in such a way that the pattern formed by the assist features is not transferred into the resist layer when irradiated.

    摘要: A method of forming a doped portion of a semiconductor substrate includes: defining a plurality of protruding portions on the substrate surface, the protruding portions having a minimum height; providing a pattern layer above the substrate surface; removing portions of the pattern layer from predetermined substrate portions; performing an ion implantation procedure such that an angle of the ions with respect to the substrate surface is less than 90°, wherein the ions are stopped by the pattern layer and by the protruding portions, the predetermined substrate portions thereby being doped with the ions; and removing the pattern layer.

    摘要: A mask for fabricating semiconductor components contains first transparent regions and second transparent regions. The second regions are laid out such that they do not act on the regions of the photoresist directly beneath them in the exposure of the photoresist through the mask. The transparent regions define a size and a shape of structures to be formed.
