Abstract: The present invention provides improvements to the use of silyating agents in semiconductor processing. More particularly, the silyating agents may be provided in combination with a substantially non-flammable ether, so that the combination is substantially non-flammable.

Abstract: The present invention relates to a process for thinning a semiconductor wafer. Two surfaces of the wafer separately form a surface-bond glue (layer) and a surface protective glue (layer). The thinning process is applied to the wafer before forming the surface protective glue. Once the baking and drying process is applied to the surface-bond glue and the surface protective glue it then cuts the wafer. Finally, it dissolves the lower solubility of the surface protective glue to obtain the finished goods. The necessity of the selection of the wafer may serve to maintain quality standards. The wafer thinning process of the present invention is suitable for the extremely thin wafer. Thus, it reduces the production cost.

Abstract: A method of growing a p-type nitride semiconductor material having magnesium as a p-type dopant by molecular beam epitaxy (MBE), comprises supplying ammonia gas, gallium and magnesium to an MBE growth chamber containing a substrate so as to grow a p-type nitride semiconductor material over the substrate. Magnesium is supplied to the growth chamber at a beam equivalent pressure of at least 1 10-9 mbar, and preferably in the range from 1 10-9 mbar to 1 10-7 mbar during the growth process. This provides p-type GaN that has a high concentration of free charge carriers and eliminates the need to activate the magnesium dopant atoms by annealing or irradiating the material.

Abstract: A method is disclosed for removing liquids from a semiconductor substrate by contacting the liquid on the substrate with a liquid which attracts the liquid on the substrate, separating the liquids from the substrate, and inducing a phase transition in a layer on the substrate. In particular, the method is applicable to removing water from a water-containing layer on the substrate by contacting the layer with a hygroscopic liquid. Trenches on a substrate can be isolated by filling the trenches with a water-containing gel formed by reacting silane and hydrogen peroxide. The gel is contacted with sulfuric acid to remove a portion of the water from the gel before annealing to form silica in the trenches. Unlike filled trenches formed by conventional technology, there are no voids in the bottom of the trenches. The method is also applicable to forming dielectric layers which cover metal lines, low-dielectric layers, and interlayer dielectric layers.
