IPC: H01S5/227
Filed: 1984-02-16
Abstract: PURPOSE:To isolate the upper portion from the sides in a mesa stripe and to suppress leak currents by a method wherein blocking layers are deposited one after another on a substrate along the sides of the mesa stripe with its cross section shaped in an inverted trapezoid. CONSTITUTION:A mesa stripe 1b is formed on an N type substrate 1 and has a cross section of an inverted trapezoid. A P type current-blocking layer 13 is formed on the substrate 1 along the flanks of the mesa stripe 1b.
