摘要： In a method for producing ferroelectric strontium bismuth tantalate having the composition SrxBiyTa2O9 (SBT) or SrxBiy(Ta, Nb)2O9 (SBTN), the element strontium, which is normally present in an amount y=2, is provided in excess in a range from 2.1≦y≦3.0. This makes it possible to carry out the heat treatment step for converting the deposited material into the ferroelectric phase at a temperature T1, which is lower than 700° C. In addition, the strontium content x can be reduced from a nominal value of 1 to 0.7.

摘要： A method for depositing an SiO.sub.2 layer, which acts as an inter-metal dielectric (IMD), is provided. The method includes the steps of applying to the topography an organodisiloxane which is dissolved in an organic solvent, the organodisiloxane is then polymerized, and the polymer formed is decomposed, the polymer changing in the process to become an SiO.sub.2 -rich layer. The method of the present invention results in SiO.sub.2 layers which achieve an excellent local and global degree of planarization and have a distinctly lower dielectric constant than SiO.sub.2 layers prepared using conventional methods.

摘要： For cleaning parasitic layers of silicon oxides or nitrides in a reaction chamber, an etching gas mixture is employed in which at least one fluoridated carbon, particularly CF.sub.4 and/or C.sub.2 F.sub.6, is the main constituent. Then, an ozone/oxygen mixture (O.sub.3 /O.sub.2) having optimally high ozone concentration is added to the reaction chamber. The etching gas mixture is excited in the reaction chamber by triggering the etching gas mixture to form a plasma, having extremely low power with an excitation frequency in the RF range. The etching gas mixture etches all surfaces in the reaction chambers free of residues with a high etching rate.

摘要： To create silicon boronitride layers that are utilized as intermetallization layers and/or as final passivation layers, the present invention provides a method wherein fluid initial compounds that already molecularly contain a part of the target composition of the silicon boronitride layer to be produced are utilized, and deposited through chemical vapor deposition in an alternating electromagnetic field. The silicon boronitride layers produced in this fashion have a dielectric constant whose value is below 4 .epsilon..sub.o and are distinguished by good insulating and blocking properties and by a high break down strength.

摘要： A method for the shrink-hole-free filling of trenches in semiconductor circuits which utilizes selective growth of a layer to be applied is described. In the method, a layer of a selective growing material is applied simultaneously to a growth-promoting layer and to a growth-inhibiting layer. Wherein raised portions which, before the layer of selective growing material is applied, are covered by the growth-inhibiting layer at least on their sides. After the growth-inhibiting layer has been applied, the growth-promoting layer is generated by anisotropic treatment on surfaces parallel to the substrate on and between the raised portions and the layer is then removed again on surfaces parallel to the substrate on the raised portions. The method makes it possible to produce in a particularly simple manner a pattern on the raised portions of which are covered by the growth-inhibiting layer on their sides and on their top whereas the bottom of trenches is covered with a growth-promoting layer.

摘要： When large-scale integrated circuits are produced, pronounced differences in height occur within conductor track levels. Those extreme topographies lead to difficulties during photo-lithographic processes, since there is a direct relationship between resolution and depth of focus. A production method for applying an insulation layer functioning as an intermetal dielectric is based on an ozone-activated selective deposition of silicon oxide. The conductor tracks are completely encapsulated with an insulation layer, so that bulges do not occur above upper edges of the conductor tracks.
