摘要: A device and a method for the processing of wafers is disclosed. One embodiment provides a method and a device in which a system wafer is bonded to a carrier work piece by using a bonding substance so as to increase the stability of the system wafer. After processing of the system wafer, the bonding effect of the bonding substance is cancelled. The system wafer can easily be detached from the carrier work piece without cutting out the carrier work piece, so that the dust exposure and the mechanical stress of the system wafer which occurs during the cutting out of the carrier work piece is avoided.

摘要: An improved process for producing adipic acid from the acidic wash waters which arise in the process for oxidizing cyclohexane with air, by treatment with nitric acid at from 10.degree. to 50.degree. C., with removal of the heat of reaction by external cooling, wherein the reaction mixture is led, at a flow velocity of at least 2.0 m/sec, as a thin layer spirally in counter-current to the coolant, under conditions which do not perturb the flow of the reaction mixture.
