    摘要: The method of the present invention provides in a simple manner, the deposition of boron nitride layers with microcrystalline cubic structure which are suitable as insulating layers in VLSI-circuits, as mask membranes in x-ray lithography, as well as coating hard substances. Due to the use of excited starting substances that already contain boron and nitrogen in one molecule and are preferably liquid or solid, and the use of a plasma-CVD-method, the method can be performed using in temperatures of below 500.degree. C. The excitation of the starting substance proceeds preferably in inductive or capacitative fashion in a hollow cathode.

    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.

    摘要: A method for controlling isolation layer thickness in trenches for semiconductor devices includes the steps of providing a trench having a conductive material formed therein, forming a liner on sidewalls of the trench above the conductive material, depositing a selective oxide deposition layer on the buried strap and the sidewalls, the selective oxide deposition layer selectively growing at an increased rate on the conductive material than on the liner of the sidewalls and top surface and removing the selective oxide deposition layer except for a portion in contact with the conductive to form an isolation layer on the conductive material in the trench. A method for fabricating vertical transistors by recessing a substrate to permit increased overlap between a transistor channel and buried strap outdiffusion when the transistor is formed is also included. A semiconductor device is also disclosed.
