Abstract: PURPOSE:To improve characteristics by the enhancement of the step coverage properties of an electrode by composing a lower layer of a PSG film and an upper layer of an SiO2 film in a mask consisting of an insulating film formed prior to the formation of a diffusion region. CONSTITUTION:An insulating film 9 shaped prior to the formation of a diffusion region 12 formed for electrode constriction is constituted of a PSG film 23 and an SiO2 film 14 etched by the mixed liquid of HF, NH4, P, and CH3COOH.

Accordingly, the step coverage properties of an electrode 10 are improved and the electrode in uniform thickness is shaped in the formation of the electrode after the formation of a mask through etching, thus acquiring a semiconductor laser element having excellent characteristics.
