Abstract
PURPOSE:To attain a high activation rate and high insulating properties by respectively bringing carbon concentration and the concentration of a deep donor level EL2 to specified values or less. CONSTITUTION:The carbon concentration of a semi-insulating GaAs single crystal wafer is brought to 2X10<15>cm<-1> or less while the concentration of a deep donor level EL2 is brought to 1X10<16>cm<-1> or less. When carbon concentration is reduced, an activation rate is improved but resistivity is lowered simultaneously.On the other hand, resistivity increases by the reduction of the concentration of the deep donor level EL2. Accordingly, the wafer excellent both in the activation rate and resistivity is acquired by regulating both concentration.
