摘要:
In an etch process for forming via openings and trench openings in a low-k dielectric layer, the material removal of an underlying etch stop layer is decoupled from the etching through the low-k dielectric in that the reduction in thickness is substantially achieved during the resist removal. For this purpose, the resist plasma etch may correspondingly be controlled to obtain the desired target thickness of the etch stop layer, wherein fluorine may be provided from an external source and/or fluorine may be generated in a controlled manner from polymer layers deposited within the etch chamber.

The effect of resist poisoning may be eliminated or at least substantially reduced in the formation of a low-k metallization layer, in that a nitrogen-containing barrier/etch stop layer is provided with a significantly reduced nitrogen concentration at an interface in contact with said low-k dielectric material. Consequently, diffusion of nitrogen and nitrogen compounds in vias formed in said low-k dielectric layer is significantly suppressed, so that in a subsequent photolithographic step, interaction of nitrogen and nitrogen compounds with the photoresist is remarkably reduced.

摘要:
A method for determining a rack force for a steering apparatus of a vehicle, in which the rack force is determined as a function of a steering angle variable which characterizes an actual wheel steering angle or a set point of the wheel steering angle. In order to specify a method for determining a rack force, with which a target steering torque can be generated such that a comfortable steering feel is imparted to the driver and the steering apparatus nevertheless gives the driver feedback that is as realistic as possible regarding the motion state of the vehicle, the method comprises: determining a variable which characterizes a lateral force on a shaft of the steering apparatus, and determining the rack force as a function of the lateral force, wherein the determination of the rack force comprises a filtering by means of a signal processing element having a proportional-differential transfer function.
摘要:
A method for determining a steering rack force (FR) for a steering system of a vehicle, in which a first steering rack force (RFD) is ascertained as a function of at least one force that occurs in the steering system or at least one torque (tor_RA) that occurs in the steering system. So as to provide less strong feedback on the force conditions in the steering system for reasons of driving comfort, in particular when this is currently not required, it is proposed to ascertain a second steering rack force (RFC) as a function of at least one vehicle variable (v, ang_RA), which characterizes the state of movement of the vehicle, and to generate a resulting steering rack force (FR) based on the first steering rack force (RFD) and the second steering rack force (RFC).

摘要:
A method and an apparatus for forming a structure on a component made of a material composed of silicon oxide, especially of silicate glass, glass ceramic or quartz, wherein in accordance with the process at least a first surface of the component a partial removal of the material by plasma etching takes place and during the plasma etching at least at the surface to be etched a substrate temperature is established which is substantially greater than 90° C. but less than the softening temperature of the material. The apparatus is equipped for this purpose with a heater for generating the substrate temperature.
摘要:
In sophisticated semiconductor devices, the integrity of the device level may be enhanced after applying a replacement gate approach by providing an additional diffusion barrier layer, such as a silicon nitride layer, thereby obtaining a similar degree of diffusion blocking capabilities as in semiconductor devices without performing a replacement gate approach.
