Abstract: An apparatus for radiatively scribing a planar semiconductor substrate along a scribelane that extends between opposing rows of semiconductor devices on a target surface of the substrate. The scribelane extends parallel to a first direction parallel to a second direction, these first and second directions lying respectively parallel to X and Y axes of a Cartesian coordinate system. Such an apparatus may include an illuminator for producing an array of light beams; a projection system for focusing the light beams onto the target surface; an actuator system for causing relative displacement of a substrate holder with respect to light beams parallel to an XY plane; and an adjustable spatial filter located between the illuminator and the substrate holder, and including motorized plates whose position is adjustable so as to at least partially block selectable light beams of the light beam array.

Abstract: An apparatus for radiatively scribing a substantially planar semiconductor substrate along a scribelane that extends between opposing rows of semiconductor devices on a target surface of the substrate, said scribelane having a length extending parallel to a first direction and a width extending parallel to a second direction, these first and second directions lying respectively parallel to X and Y axes of a Cartesian coordinate system, comprising: A substrate holder for holding the substrate; An illuminator for producing an adjustable array of several light beams; A projection system for focusing said light beams onto said target surface of the substrate when held on the substrate holder; An actuator system for causing relative displacement of the substrate holder with respect to said light beams parallel to an XY plane, which apparatus further comprises: An adjustable spatial filter located between said illuminator and said substrate holder, comprising a plurality of motorized plates whose position can

Abstract: The invention relates to a process to separate butadiene dimers from a mixture comprising butadiene dimers and alkyl-3-pentenoate and/or isomers thereof wherein the butadiene dimers are separated from said mixture by distillation in the presence of an alcohol and in that the distillation is effected at a bottom temperature of between 80 and 200° C. Examples of frequent occurring butadiene dimers are 4-vinylcyclohexene and 1,3,7-octatriene. Examples of the alcohol are monohydroxy aliphatic alcohols.

Abstract: The invention relates to a method for preparing a coffee concentrate, wherein the coffee is subjected to two extractions, while the second extraction is carried out at a higher temperature than the first extraction. The method is suitable for preparing liquid as well as solid concentrates. The method produces a new concentrate that forms a further aspect of the present invention.

Abstract: A continuous hydroformylation process for producing an aldehyde comprising 1) reacting an olefinically unsaturated compound, carbon monoxide and hydrogen in the presence of a rhodium-organobisphosphite complex catalyst at a partial pressure of carbon monoxide and hydrogen, and 2) exposing a mixture comprising at least a portion of the catalyst of 1) to a gaseous mixture comprising hydrogen at a pressure that is greater than the partial pressure of carbon monoxide and hydrogen during the reaction.
