Title: Light emitting diode wafer and its manufacture
Inventor: KIKUCHI YUKIO
IPC: H01L21/208
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To obtain a light emitting diode wafer in which a fine crystal product generated in the growth of a clad layer is prevented from being applied to the clad layer, by a method wherein a second thin-film clad layer in which a specific Al mixed crystal ratio is high is formed on a first clad layer under an active layer. SOLUTION: A first AlGaAs clad layer 2 which is grown on a substrate 1, a second AlGaAs thin-film clad layer 2' which is grown on it, an AlGaAs active layer 3 which is grown on it and an AlGaAs window layer 4 which is grown on it constitute this light emitting diode wafer. Then, the Al mixed crystal ratio of the first clad layer 2 is designated as X1. The Al mixed crystal ratio of the second thin-film clad layer 2' is designated as X2. The Al mixed crystal ratio of the active layer is designated as Y. Then, the wafer has a relationship of X2>=X1>Y. Consequently, a fine crystal by-product which is grown during the growth of the clad layer is dissolved in the raw-material solution of the second clad layer 2' so as to be excluded. As a result, it is possible to prevent the by-product from being applied to the clad layer.

Abstract: PURPOSE:To minimize the capacity of a voltage dividing capacitor by providing series-connected switching elements for controlling the application of voltage to the primary winding of a high voltage transformer, a plurality of voltage dividing capacitors, and a resonance capacitor. CONSTITUTION:Switching elements 5a, 5b connected in series to each other are connected in series to the primary winding 4a of a booster transformer 4. Further, a plurality of voltage dividing capacitors 14a, 14b are connected in parallel to each of the elements 5a, 5b.

When the elements 5a, 5b are OFF, the resonance circuit of the capacitor 3 and the winding 4a is resonated, and the voltage V1 of the winding 4a is changed to a sinusoidal waveform. At this time, the voltages applied to the individual elements 5a, 5b are the voltages divided by the capacitors 14a, 14b. Thus, since the capacities of the capacitors 14a, 14b can be sufficiently smaller than that of the capacitor 3, an inexpensive small-size ceramic capacitor can be used.
