Title: Manufacture of compound semiconductor
Inventor: SASAJIMA YUICHI
IPC: H01L21/205
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To efficiently dope an epitaxial GaAs, AlGaAs, or InGaAs semiconductor substrate with carbon in a relatively small etching amount at growing time by using carbon trichloride monobromide as a carbon source at the time of doping the semiconductor substrate with carbon. SOLUTION: In a method for manufacturing compound semiconductor in which a compound semiconductor having at least one carbon-boped epitaxial p-type semiconductor is manufactured by the metal organic vapor phase epitaxial growth method (MOVPE method), carbon trichloride monobromide is used as a carbon source at the time of adding carbon to the epitaxial p-type semiconductor layer. The compound semiconductor can be GaAs, AlxGa1-x As (0<x<=1), or InyGa1-yAs (0<y<=0.5). Since the carbon trichloride monobromide is chemically stable, the doping can be controlled stably at the time of adding the carbon to the compound semiconductor composed of GaAs, InGaAs, AlGaAs, etc.

Abstract: PURPOSE:To perform arbitration at a high speed by having outputs to 2<n-1> pieces of buses against a priority number of (n) digits and then driving the output lines up to the a-th one against a given priority number (a). CONSTITUTION:When an arbitration enable input AE 11 is equal to 1, a priority output PO 12 up to the a-th one is set at 1 against a given priority number (a).

Title: Oxygen analyzing method
Inventor: IZUMIDA SHINYA
IPC: G01N27/28
Filed: 1985-09-26
Abstract: PURPOSE:To measure the amount of oxygen accurately even when a base current is not balanced by calculating previously an approximate current curve which connects smoothly two base currents to a time base before and after sample oxygen is introduced and discharged. CONSTITUTION:A constant DC voltage is applied to the solid-state electrolyte 20 in an oxygen pump 8 and the oxygen in carrier gas is discharged from a flow passage; and then oxygen from the sample is discharged similarly and the amount of the oxygen in the sample is measured from the quantity of electricity required for the discharging. The curve i3 which connect a current i1 which flows in an electrolyte 20 in the balanced state before the sample gas is introduced and a balanced base current i2 after the oxygen is discharged is calculated previously from the currents i1, a current i0 during sample gas analysis, and the balanced base current i2. Therefore, even when the base current is not balanced before and after the measurement of sample oxygen, an integral current value P is calculated from the approximate curve to measure the amount of oxygen accurately, thereby shortening the measurement time.
