Title: Compound semiconductor epitaxial wafer
Inventor: UDAGAWA TAKASHI
IPC: H01L21/205
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To obtain a wafer having uniform characteristics in the plane by comprising a low temperature buffer layer principally of a plurality of single crystal grains having spindle-like cross-section and setting the interval between the top of adjacent single crystal grains at a constant value longer than the breadth thereof or less thereby defining the crystallographic quality required for the low temperature buffer layer. SOLUTION: A low temperature buffer layer 109 principally comprises single crystal grains 104 having cross-sections substantially circular or polygonal close to circular, growing from an interface 102 to a crystal substrate 101. The single crystal grain 104 has spindle-like cross-section of pointed top. Breadth W107 of the spindle-like single crystal grain represents the maximum breadth of each grain which is in the range of 2-40nm. The interval L108 between the top of adjacent spindle-like single crystal grains is in the range of W-(W+100)nm. L represents the distance between adjacent single crystal grains. If L=W, it means that the single crystal grains are abutting each other. L is related to the surface density of the single crystal grain.

Title: Timing signal generating circuit
Inventor: KATO AKIRA
IPC: H03K5/04
Filed: 1987-09-09
Abstract: PURPOSE:To adjust the pulse width consecutively with high accuracy by adopting the circuit constitution such that a pulse width fed to a gate input is adjusted by a voltage applied to an external power terminal. CONSTITUTION:The pulse width of a pulse signal fed to an input terminal IN of the 1st gate G1 is adjusted by using a voltage fed to an external power terminal VC. The output waveform of a 2nd gate G2 has a fast leading because an emitter follower circuit 30 is acted at the leading and a capacitor CX acts like a speedup capacitor. On the other hand, the trailing time of the output waveform of the 2nd gate G2 is adjusted by using the voltage given to the external power terminal VC at its leading. Thus, the pulse width is set accurately to 1/2 of the period.

IPC: C30B29/40
Filed: 1987-09-09
Abstract: PURPOSE:To reduce polarization of irradiation of a molecular beam for a substrate by closing a shutter, cutting the molecular beam off and rotating the substrate by 180 deg. while smoothing a single atomic layer grown on the substrate when oscillation waveforms of a measured reflected fast electron beam diffraction image are maximized. CONSTITUTION:A molecular beam is irradiated on a stopped substrate 7 and a single atomic layer is grown on the substrate 7 as oscillating waveforms of a reflected fast electron beam diffraction image of the substrate are being measured. When the oscillating waveforms of the measured reflecting fast electron beam diffraction image are maximized, shutters 51a, 52a, 53a are closed, and a molecular beam irradiated from molecular beam source cells 51, 52, 53 are shut off. After the shutters are closed, the substrate 7 is rotated by 180 deg. in fixed time for smoothing the single atomic layer with shutting the molecular beam off for fixed time and smoothing the single atomic layer deposited on the substrate and polarization of irradiation of the molecular beam for the substrate is reduced. Therefore, exact layers of the flat single atomic layer can be grown without polarization.
