    摘要: As a pretreatment of a substrate, a substrate of Si having the (111) surface orientation as a main surface is soaked in hydrofluoric acid, so as to form a H atomic layer for terminating dangling bonds on the main surface of the substrate. Then, the substrate is placed in a highly evacuated growth chamber in an MBE system, and a Ga molecular beam and a Se molecular beam are supplied onto the H atomic layer on the substrate, so as to grow a buffer layer of GaSe, that is, a van der Waals crystal. Next, with the supply of the Se molecular beam stopped, a N2 gas activated by using radio frequency or electron cyclotron resonance is supplied instead as a nitrogen source onto the buffer layer on the substrate, so as to form a semiconductor layer of GaN.

    摘要: The light-emitting diode device of the present invention includes an active layer, a p-type contact layer, a Schottky electrode and an ohmic electrode. The active layer is formed over an n-type semiconductor substrate. The contact layer is formed over the active layer. The Schottky electrode is selectively formed on the contact layer and makes Schottky contact with the contact layer. The ohmic electrode is formed to surround the Schottky electrode on the contact layer and to be electrically connected to the Schottky electrode and transmits the light emitted from the active layer.

    摘要: A wavelength conversion device exhibiting an excellent wavelength conversion efficiency is provided by forming it in such a manner that an LiTaO.sub.3 substrate is subjected to a proton exchange treatment to form a proton-exchange layer before the proton-exchange layer is subjected to heat treatment to form a domain-inverted structure. Heat treatment is performed at a high temperature rising speed to prevent the thermal diffusion of the proton-exchange layer so that the expansion of the domain-inverted structure to be formed in the proton-exchange layer is restrained. As a result, a higher harmonic wave wavelength conversion device can be provided.

    摘要: Disclosed is a liquid phase epitaxial growth method using a slider having a recess which receives a semiconductor substrate, and a growth boat having a solution holder which holds plural kinds of solutions for use in epitaxial growth, in which method, epitaxial growth of a layer having thickness of less than 500 .ANG. is carried out under the condition that the slider is sliding in one direction, i.e., without stopping the sliding movement of the slider. Thereby, the thickness of the growth layer is controlled by controlling the time when the substrate contacts the solution, or by the sliding speed of the slider.

    摘要: An underlying conductive film made of iridium and having a thickness of about 0.1 &mgr;m is formed in a contact hole formed in an insulating film covering a transistor formed in a substrate, except in the top portion of the contact hole. The underlying conductive film covers the sidewall portions of the contact hole and the top surface of the drain region but does not completely fill in the contact hole. A plug made of platinum is filled in the contact hole up to the top portion thereof. Over the contact hole of the insulating film, there is formed a capacitor composed of a lower electrode made of platinum, a capacitor insulating film made of SrBi2Ta2O9, and an upper electrode made of platinum in contact relation with the respective upper ends of the underlying conductive film and the plug.
