Abstract: PURPOSE:To prevent the production of pin holes or the like and the generation of strain due to change of lattice parameters, by growing single crystal ZnSe for providing end-face protecting films on the resonance faces of a semiconductor laser consisting of InGaAlP and InGaAsP layers. CONSTITUTION:An N-type InGaAlP layer 3 as first clad layer, an undoped InGaAlP layer 4 as active layer, a P-type InGaAlP layer 5 as second layer and a P-type GaAs layer 5' as cap layer are provided on an N -GaAs crystal substrate 2, sequentially in that order. An oxide film 6 is further provided thereon, and a metallic layer 7 to be an upper electrode and a metallic layer 1 to be a lower electrode are provided so as to entirely cover the top and bottom faces. The wafer is cleaved to produce stripe-shaped substrates. Single crystal ZnSe is grown on the side faces of each substrate so as to form end-face protecting films 8. According to this method, the interface between the semiconductor laser and the end-face protecting film is allowed to have improved crystallizability, and hence no water or oxygen is adsorbed or transmitted therethrough, and the cleaved surface is prevented from being damaged, corroded or oxidized.

Abstract: PURPOSE:To improve the resolution of a solid state image pickup element by forming by a self-alignment an overflow drain region, an overflow control gate region and a channel stopper region and integrating picture elements as many as possible in a limited area. CONSTITUTION:An extremely thin SiO2 film 22 and an ordinarily thick photoresist layer 23 are laminated and covered on a P type Si substrate 1, and windows 24, 25 corresponding to an overflow control gate region 4 and a channel stopper region 5 to be formed later are opened. Then, P type impurity ions are injected, P type regions 4, 5 are formed on the surface layer of the substrate 1 exposed in the windows 24, 25, only the layer 23 is removed, with the remaining film 22 as a mask a high temperature nitriding treatment is performed, and thick SiO2 film 26 is formed on the regions 4, 5. Thereafter, the film 22 is modified to an SiO2 film 27, the overall surface is covered with a photoresist layer 28, a window 29 is opened, and an N type overflow drain region 2 is formed in the substrate 1 between the regions 4 and 5 by N type ion injection.
