摘要:
A photoresist system that is easily structurable and, in particular, is suitable for the deep ultraviolet range is provided. An increased etching resistance to a halogen-containing plasma is produced in a lithographically generated photoresist structure by treatment with a reactant. The reactant comprises predominantly aromatic structures and includes reactive groups that are suitable for chemical reaction with further reactable groups of the photoresist. In an embodiment, the photoresist includes anhydride or epoxy groups that are suitable for structuring with deep ultraviolet light.

A method of manufacturing a semiconductor package includes embedding a semiconductor chip in an encapsulant. First contact pads are formed on a first main face of the semiconductor package and second contact pads are formed on a second main face of the semiconductor package opposite the first main face. A diameter d in micrometers of an exposed contact pad area of the second contact pads satisfies d≧(8/25)x+142 μm, where x is a pitch of the second contact pads in micrometers.

A semiconductor device is disclosed. One embodiment includes a semiconductor substrate and at least two insulating elements located above the semiconductor substrate or above a mold compound embedding the semiconductor substrate. The at least two insulating elements have a first face facing the semiconductor substrate or the mold compound and a second face facing away from the semiconductor substrate or the mold compound. A conductive element for each of the at least two insulating elements extends from the first face of the insulating element to the second face of the insulating element.

The invention relates to a layer arrangement and to a process for producing a layer arrangement. The layer arrangement has a layer which is arranged on a substrate and includes a first subregion comprising decomposable material and a second subregion which is arranged next to the first subregion and has a useful structure comprising a non-decomposable material. Furthermore, the layer arrangement has a covering layer on the layer comprising decomposable material and the useful structure, the layer arrangement being designed in such a manner that the decomposable material can be removed from the layer arrangement.
摘要:
Bis-o-aminophenols, which carry on at least one of their hydroxyl groups a tert-butoxy-carbonyl group, can be reacted with dicarboxylic acids to give the corresponding poly-o-hydroxyamides. Following cyclization to the polybenzoxazole, these polymers have a lower dielectric constant than compounds prepared from corresponding poly-o-hydroxyamides which do not carry any tert-butoxycarbonyl group.
