Abstract

In a compound semiconductor device such as a magnetoresistance element or Hall element having a compound semiconductor portion such as of InSb and an electrode portion, a portion of the compound semiconductor portion is exposed to energy irradiation to be converted into an alloy state or amorphous state and rendered conductive to form the electrode portion. The portion rendered conductive is contiguous to and in ohmic contact with the unexposed portion of the compound semiconductor and used as a shorting bar electrode or an external lead bonding pad.
