Filed: 1987-06-15
Abstract: PURPOSE:To minimize the defective crystallization occurring in the part near an interface by a method wherein a hetero-interface, after once being made amorphous, is recrystallized to form a hetero-structured single crystal thin film. CONSTITUTION:Both sides near an interface of a hetero-structure formed by the ordinary hetero-epitaxial growing process are once made amorphous using the ion implantation process and then annealed to rectystallize the amorphous region by the solid crystal growing process.

Abstract: PURPOSE:To obtain a quality insulating film with a small surface level density through a process consisting of, when an oxide film is formed on a GaAs substrare, prebiously, providing an additional layer of thin metallic-As film or a low-class As oxide layer and feeding an As component to the substrate in substrate heat-oxidation process. CONSTITUTION:A thin metallic-As film 2 is vacuum-deposited or As is deposited in the low vacuum whose O2 pressure is set to 10<-4>-10<-3> Torr on the surface of a GaAs substrate 1. A thin low-class oxide film 2 is deposited thereon. Next, thus- obtained work is heat-treated in O2 gas or the mixture gas of O2 and N2 through two-step reaction.

Filed: 1988-06-14
Abstract: PURPOSE:To make it possible to hold a substrate in a state that the substrate is reliably kept planar by a method wherein an insulating layer having a large dielectric constant is formed into a structure wherein the capacity to be occupied by the insulating layer becomes the largest at the central part of the layer and the capacity closer to the outer periphery of the layer is gradually reduced, whereby the substrate is constituted in such a way that the static attraction force is always the largest in its central part. CONSTITUTION:In order to contrive so that the central part of a substrate 4 is first attracted and the parts close to the outer periphery of the substrate 4 are gradually attracted, it is necessary that a static attraction force is always the largest in the central part of the substrate 4. Therefore, spaces are formed in an insulating layer 3 by recessed grooves 5 and so on, but the spaces are decreased toward the central part of the substrate 4 among these spaces and increased toward the outer periphery are made large. Moreover, if the substrate 4 is placed on this layer 3 and a voltage is applied between an electrode 2 and the substrate 4, a static electric force toward the central part of the substrate 4 becomes larger than toward the outer periphery. Thereby, the flatness of the substrate can be kept with high precision.
