  • Publication number: 20070164276
    Abstract: Layers are produced, where the layers include a first layer formed of a metal and a second layer formed of an organic compound, the metal and the organic compound entering into an interaction, so that the layer serves as an electroactive layer for nonvolatile memories, the metal layer being deposited onto a substrate and, if appropriate, patterned, then being coated with an organic compound and being treated with a second organic compound.

  • Patent number: 7244803
    Abstract: A dielectric for aluminum and copper metalizations is stable at high temperatures. Surprisingly, in spite of the elimination of water during the cyclization, the polymeric dielectrics are very suitable for filling narrow trenches. The filled trenches exhibit no defects and bubbles or cracks. The polybenzoxazoles have dielectric constants of k?2.7 and are suitable as an electrical insulator. Furthermore, these materials adhere very well on all surfaces relevant for micro-electronics.

  • Patent number: 6900284
    Abstract: Poly-o-hydroxyamides are cyclicized to obtain polybenzoxazoles. The poly-o-hydroxyamides provide effective filling of trenches. In particular, the poly-o-hydroxyamides can fill trenches having a width of less than 100 nm and an aspect ratio of more than 4. Further, the polybenzoxazoles of the invention are very suitable for the damascene process. A dielectric can be made from the polybenzoxazole. In turn, semiconductor devices can include the dieletric. Processes for making the poly-o-hydroxyamides, polybenzoxazoles, and semiconductor devices are included.

  • Patent number: 6861560
    Abstract: A bis-o-aminophenol has a formula I These bis-o-aminophenols permit the preparation of polybenzoxazoles stabilized at high temperatures. The bis-o-aminophenols are preferably prepared from the corresponding diols, which are first nitrosated. The nitroso compound is then reduced to the amino compound by hydrogenation with Pd/C and H2.

  • Patent number: 6806344
    Abstract: Novel poly-o-hydroxyamides can be cyclized to give polybenzoxazoles which have a good diffusion barrier effect with respect to metals. The poly-o-hydroxyamides can be applied to a semiconductor substrate by customary techniques and converted into the polybenzoxazole in a simple manner by heating. This results in a good barrier layer with respect to diffusion of metals. This allows the diffusion barrier between conductor track and dielectric to be substantially dispensed.
