    摘要: A thin film forming apparatus is formed of a vacuum chamber, a base plate holder for holding a base plate near a central part of the vacuum chamber, and ECR plasma generating devices respectively connected to both side portions of the vacuum chamber. A magnetic field generating device is situated adjacent to the vacuum chamber for generating a predetermined magnetic field in the vacuum chamber, and a gas introducing system is connected to the vacuum chamber for introducing a reaction gas into the vacuum chamber. Since the base plate holder has a shape corresponding to an external shape of the base plate, a distance between the base plate and the base plate holder is uniform. The films with uniform thicknesses can be formed on both surfaces of the base plate.

The drive substrate 1 has a plurality of thin film transistors each for switching one of the pixel electrodes, a first interlayer insulating film for covering the thin film transistors, interconnect electrodes patterned on the first interlayer insulating film and connected to the thin film transistors, a second interlayer insulating film for covering the interconnect electrodes and a black matrix patterned on the second interlayer insulating film and used for shielding the thin film transistors beneath the second interlayer insulating film. The black matrix is covered by a planerization layer and the pixel electrodes are patterned on the planerization layer. The pixel electrodes are connected to the interconnect electrodes through the black matrix 10 which is made up of a metal film. In a display device of the active matrix type, an on-chip black structure is thus obtained by providing a black matrix also referred to as a light-shielding layer on a drive substrate.

    摘要: A process for the production of .alpha.-hydroxy acids or .alpha.-hydroxyamides in which an .alpha.-hydroxynitrile compound or a mixture consisting of an aldehyde and prussic acid, which corresponds to the nitrile compound, is allowed to undergo a microbial reaction to produce the corresponding .alpha.-hydroxy acid or .alpha.-hydroxyamide, wherein the improvement resides in that phosphite ions or hypophosphite ions are allowed to be present in the reaction system. According to the present invention, since hydrolysis or hydration of nitrile compounds can be carried out by constantly keeping a low concentration level of aldehydes which are considered to be a cause of the enzyme inhibition in the reaction system, the enzyme activity can be maintained stably for a prolonged period of time and the formed acids or amides can therefore be accumulated in a high concentration.
