摘要:
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.

Poly-o-hydroxyamides include binaphthyl substituents as repeating units. The poly-o-hydroxyamides can be cyclized to give the polybenzoxazole by heating. Pore formation occurs, so that a dielectric having a very low dielectric constant k of less than 2.5 is obtained.

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.

摘要:
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.

The present invention provides a process for wiring electrical contact sites, in particular on the surface of an electronic or microelectronic component, with the following steps: applying and patterning at least one dielectric on the component surface; currentlessly depositing a conductor starting layer for producing metal wiring interconnects and substitute contact sites with short-circuit contacts for interconnecting the individual metal wiring interconnects and the corresponding electrical contact sites; reinforcing the conductor starting layer by a common electrodepositing process; and separating the short-circuit contacts for separating the electrical contact sites or the contact sites of the wiring from one another.

摘要:
A method for metallizing dielectrics includes applying a photosensitive dielectric to a substrate. The dielectric is then exposed to light through a mask, is seeded with a metal and is subjected to a temperature treatment. Afterwards, the dielectric is chemically metallized. Alternatively, the dielectric can be first be seeded with a metal after being applied to the substrate, and can then be exposed to light through a mask. Afterwards, excess seeding material is removed and the dielectric is chemically metallized.
