IPC: H01S5/042
Filed: 1982-09-13
Abstract: PURPOSE:To obtain a fast responsing light-emitting element by a method wherein a contact potential electrode is provided on the circumference of a current injection electrode, and the minority carrier storage effect on the circumference of a light-emitting region is suppressed. CONSTITUTION:A Zn-added In0.74Ga0.26As0.56P0.44 active layer 2, a Zn-added InP layer 3 and an Sn-added In0.89Ga0.11As0.24P0.76 layer 4 are superposed on the surface (100) of an Sn-added InP substrate 1. A circular Zn diffusion layer 4a and a concentric ring-shaped Zn diffusion layer 4b are provided in the layer 4, Au-Zn alloy electrode 5 and 6 are attached, and a ring-shaped Au-Ge-Ni alloy electrode 7 is attached to the substrate 1. When the electrode 7 is grounded and a modulation signal voltage is applied to the electrode 5, the electrode 6 is also grounded. According to this constitution, minority carrier is not accumulated on the P-N junction located outside the region 4b, the minority carrier to be accumulated due to the drop of junction voltage is markedly reduced even at the P-N junction located in the vicinity of the light-emitting region outside the region 4a, and there is no deterioration in responsing speed. Also the current between the electrodes 5 and 6 is very small and almost no lowering in optical output is observed.

Title: Manufacture of semiconductor device
Inventor: YAMAGISHI HIDETAKA
IPC: H01L21/265
Filed: 1986-07-07
Abstract: PURPOSE:To prevent phosphorus concentration from decreasing on the surface of a silicon without disturbing the recovery of a crystal defect due to ion implantation by heat treating a semiconductor device in a gas atmosphere including 0.5-1.5% of small amount of oxygen in nitrogen in a step of pressing after ion implanting the phosphorus. CONSTITUTION:When phosphorus ions are implanted to form a highly concentrated N-type semiconductor region 1, it is pressed in a gas atmosphere including 0.5-1.5% of oxygen in nitrogen. Thus, a thin oxide film 3 formed by the small amount of oxygen suppresses the flying of the phosphorus from the surface of a silicon to prevent a surface concentration from decreasing, and since the oxygen is of small amount, it does not disturb the recovery of a crystal defect 4 due to ion implanting.
