摘要:
The present invention relates to polymer powders with high rubber content and to their use as impact modifiers for rigid polyvinyl chloride (PVC) applications, and also to thermoplastic molding compositions comprising halogen and comprising the polymer powder, and to the use of the molding compositions for production of moldings.
摘要:
A method for operating an internal combustion engine, injects fuel directly into a combustion chamber as a main injection, a postinjection and optionally also as a preinjection. An injection nozzle with a plurality of injection bores effects the preinjection and the postinjection preferably which is carried out cyclically. To minimize wetting of the combustion chamber walls, during the postinjection the partial quantities of fuel and a lift of the nozzle needle of the injection nozzle are set so that, for each partial quantity of the postinjection injected into the combustion chamber, the reach of the respective fuel jet in the combustion chamber is limited and the reach is less than the distance to a combustion chamber boundary.
摘要:
An SOI transistor element and a method of fabricating the same is disclosed, wherein a high concentration of stationary point defects is created by including a region within the active transistor area that has a slight lattice mismatch. In one particular embodiment, a silicon germanium layer is provided in the active area having a high concentration of point defects due to relaxing the strain of the silicon germanium layer upon heat treating the transistor element. Due to the point defects, the recombination rate is significantly increased, thereby reducing the number of charged carriers stored in the active area.

摘要:
Resist masks exposed to high-dose implantation processes may be efficiently removed on the basis of a combination of a plasma-based etch process and a wet chemical etch recipe, wherein both etch steps may include a highly selective etch chemistry in order to minimize substrate material loss and thus dopant loss in sophisticated semiconductor devices. The first plasma-based etch step may provide under-etched areas of the resist mask, which may then be efficiently removed on the basis of the wet chemical etch process.
