摘要： A method of fabricating a semiconductor crystal mesa stripe whose waist section is narrower than the upper plane of said mesa stripe, said method comprising the steps of forming a first striped mask (41) on a semiconductor wafer (40) in order to fabricate a prescribed mesa stripe (43), linearly arranging a plurality of second striped masks (42 1 , 42 2 ), narrower than said first striped mask (41) by the prescribed waist width of the main mesa stripe (43), on said semiconductor wafer (40) at prescribed intervals and in parallel with said first striped mask (41) in order to fabricate monitor mesa stripes (44 1 , 44 2 ); and of subjecting said semiconductor wafer (40) to mesa etching.

摘要： An active layer is formed on an n-type InP buffer layer (11) of a substrate (10). A pair of strip-shaped grooves are formed into the active layer to divide it into a contract portion (12a) and side portions. A p-type InP cladding layer (15) is deposited on the entire surface of the active layer and grooves. The cladding layer (15) is selectively etched to form a mesa portion including the central active portion (12a) and expose the buffer layer (11). An insulating film (18) is coated on the mesa portion and buffer layer, so that a semiconductor light-emitting device is manufactured.

摘要： A semiconductor laser device comprises a substrate (10) having an n-type buffer layer (11), a semiconductor laser element and auxiliary element, provided side by side on the buffer layer. The semiconductor laser element includes a mesa portion having a p-type low resistant semiconductor region (13c) provided above the buffer layer, an active region (12a) consisting of a semiconductor formed on the buffer layer and low resistant region, a pair of buried portions (13a) integrally formed with the low resistive sregion and formed on and contiguous to opposite sides of the active region in the width direction. A lateral hole (35) is provided between the buffer layer and low sresistive region on the side of buried portion. The auxiliary element includes a high resistive regions (13d) integrally formed with the low resistant region and positioned on the sides of low resistive region.
