Title: Semiconductor optical modulator
Inventor: NODA YUKIO
IPC: H01S5/12
Filed: 1986-02-21
Abstract: PURPOSE:To obtain a semiconductor optical modulator which performs fast modulation without increasing a modulating voltage by increasing the carrier density of a clad layer adjoining to an optical waveguide layer toward P-N junction or Schottky junction. CONSTITUTION:A lower clad layer 8 is formed increasing in carrier density from the side of an InP substrate 1 to the optical waveguide layer 3. Thus, the carrier density of the lower clad layer 8 is varied to applying an electric field to the whole of the lower clad layer 8 without increasing the modulating voltage even if the lower clad layer 8 is increased in layer thickness, thereby increasing the width W of a depletion layer. The size of the P-N junction capacity decrease in inverse proportion to the width W of the depletion layer, so high-speed modulation is performed without increasing a reverse voltage.

Abstract: PURPOSE:To reduce the temperature and time for diffusing phosphorus in the back surface of a substrate and to increase gettering effect by implanting in advance ions on the back surface of the substrate to form a distortion layer. CONSTITUTION:When Ar ions are implanted in advance on the back surface of a substrate to form a distortion layer, the temperature and time for dispersing phosphorus in the back surface of the substrate can be reduced. Dosage of 5X10<15>/cm<2> may be performed at 100keV. A conventional back surface phosphorus diffusion is limited to the initial step of the process, but according to  this method, it can be performed at the time of exerting the gettering most  effectively at the final stage of the process. Or, it can be performed together  with the phosphorus diffusing step at the time of forming an element on the  front surface of the substrate, and a special surface mask formation is not  necessary to treat the back surface phosphorus diffusion, thereby providing  advantageous simplification of the process.
