摘要： A film of a II-VI group compound semiconductor of at least one of elements belonging to the II group of the periodic table and at least one of elements belonging to the VI group of the periodic table is deposited on a substrate. When the film is deposited on the substrate, a plasma of nitrogen in an excited state is applied to the substrate while removing charged particles from said plasma by a charged particle removing means. The deposited film of a nitrogen-doped II-VI group compound semiconductor has an increased percentage of activated nitrogen atoms and improved crystallinity.

摘要： A semiconductor laser formed into a double hetero junction structure comprising an n-type cladding layer and a p-type cladding layer with an active layer interposed therebetween. The p-type cladding layer has a laminated structure consisting of a first cladding layer of (Al.sub.x Ga.sub.1-x)InP disposed on one side adjacent to the active layer and a second cladding layer of Al.sub.y Ga.sub.1-y As disposed on the reverse side. A deterioration prevention layer of Al.sub.z Ga.sub.1-y As is included in the first cladding layer at a position spaced apart from the second cladding layer by a predetermined thickness. In addition, the second cladding layer is partially removed, and a current stricture layer is formed at the removed portion. Due to the above design, the semiconductor layer is capable of retaining high reliability with certainty.
