The present invention relates to a novel dispensable medium for etching doped tin oxide layers having non-Newtonian flow behaviour for etching surfaces in the production of displays and/or solar cells and to the use thereof. In particular, it relates to corresponding particle-free compositions by means of which fine structures can be etched selectively without damaging or attacking adjacent areas.
摘要:
Bone cements containing polyacrylates or polymethacrylates and an X-ray contrast medium can be prepared by functionalizing the X-ray contrast medium with (meth)acrylate groups prior to being coating with melamine-formaldehyde resin and subsequent polymerization. The invention resultant bone cement can be used for anchoring prosthesis components in bone, for stiffening bone, as bone screw fixing plug and as implants for anchoring screws.
摘要:
The present invention relates firstly to HF/fluoride-free etching and doping media which are suitable both for the etching of silicon dioxide layers and also for the doping of underlying silicon layers. The present invention also relates secondly to a process in which these media are employed.

The present invention relates to a novel printable etching medium having non-Newtonian flow behavior for the etching of surfaces in the production of solar cells and to the use thereof. In particular, the invention relates to corresponding particle-containing compositions by means of which extremely fine structures can be etched very selectively without damaging or attacking adjacent areas.
摘要:
The present invention relates to a novel etching medium for the structuring of transparent, conductive layers, as are used, for example, in the production of liquid-crystal displays (LCDS) using flat-panel screens or of organic light-emitting displays (OLEDs) or in thin-film solar cells. Specifically, it relates to particle-free compositions by means of which fine structures can be etched selectively in oxidic, transparent and conductive layers without damaging or attacking adjacent areas. The novel liquid etching medium can advantageously be applied by means of printing processes to the oxidic, transparent, conductive layers to be structured. Subsequent heat treatment accelerates or initiates the etching process.
摘要:
The present invention relates to particle-containing etching media in the form of etching pastes which are suitable for the full-area or selective etching of extremely fine lines or structures in silicon surfaces and layers and in glass-like surfaces formed from suitable silicon compounds. The present invention also relates to the use of the pastes according to the invention in processes for etching surfaces of this type.
