Abstract: It has been discovered that catalysts may be modified by depositing an agent derivative from an agent such as an organometallic compound upon them. Such a modification gives a catalyst useful in increased selectivity to para-substituted alkyl benzenes, such as para-xylene (PX), through reacting an aromatic compound such as toluene and/or benzene with a methylating agent from hydrogen and carbon monoxide and/or carbon dioxide and/or methanol. Using these selectivated catalysts, para-substituted alkyl benzenes can be recovered in a selectivity of 80% or greater, significantly better than the equilibrium concentration of 24%.

Abstract: A mask (stencil) having cells (openings) is disposed on a surface of a heater stage, and is then then filled (printed) with solder paste. Then a substrate is assembled to the opposite side of the mask. Then the solder paste is reflowed. This may be done partially inverted. Then the mask is separated from the substrate, either before or after cooling. Solder balls are thus formed on the substrate, which may be a semiconductor wafer. A method for printing the mask with solder paste is described.

Abstract: To drill micro-holes in a multi-layer substrate having a first metal layer and at least one second metal layer, and having a dielectric layer arranged between two metal layers, use is made of a solid-state laser. The beam of the laser, in a first operation, ablates the first metal layer and, in a second operation, ablates the dielectric layer down to the second metal layer. In the first operation, the laser beam is set to a repetition frequency of at least 15 kHz, focused onto the first metal layer and moved in a circle corresponding to the diameter of the desired hole, in such a number of passes until this metal layer is cut through. Then, in the second operation, the laser beam is set to a preferably lower repetition frequency, directed out of focus onto the dielectric layer exposed in the hole and moved, with a circumferential velocity which is higher compared with the first operation, in one or more concentric circles, until the dielectric layer is ablated in the hole region.
