Webto a method for low-cost manufacturing. The ohmic con-tact material for p-type InP generally employs AuZn and AuBe, which add the p-type impurities Zn and Be to Au as the base metal to achieve a lower contact resistivity below the 10-5 Ωcm2 range. These contacts achieve a low contact resistivity by being annealed after deposition on WebWe describe here a new contact metallization scheme consisting of Pd/Ge/n-GaAs which requires sintering rather than melting in order to produce ohmic contacts. The sintering is done at temperatures ranging from 350°C, 15 min to 500°C, 2 h depending on the doping level of n-GaAs (10 18 -10 16 cm -3 .
WebAbstract The open-tube diffusion of zinc is used for the preparation of p-type layers in gallium arsenide. The process provides the capability of forming reproducible deep diffusions (0.4–2 Μm) over short diffusion times and in the temperature range 600–650 ‡C. TiPdAu contacts are prepared on these layers. WebLow-resistance p-type ohmic contacts for high-power InGaAs/GaAs-980 nm CW semiconductor lasers [J].
