英文摘要 | PURPOSE:To obtain a semiconductor laser which is small in astigmatism by a method wherein a mesa stripe is formed using an insulating film as a mask for selective growth so as to enable both the ends of the mask to extend much from the edge of the mesa stripe. CONSTITUTION:An N-type (Al0.6Ga0.4)0.5In0.5P layer 2, an active layer 3, a clad layer 4, and a cap layer 5 are successively formed on an N-type GaAs substrate 1 through a low pressure MOVPE method. A stripe-like SiO2 mask 9 7mum in width is formed through photolithography, the cap layer 5 is selectively etched into a mesa shape 3mum in width, in succession the layers under the layer 5 are etched. Thereafter, leaving the mask as it is, a second growth is carried out to form an N-type GaAs layer 6. After the mask is removed, a third growth is executed to form a buried layer 7 and a contact layer 8. Lastly, a P and an N electrodes are formed, and the substrate 1 is so cleaved as to make a cavity 250mum in length and separated into chips. |
