GaAs crystals can be doped with various elements to achieve the required electrical conductivity on semi-insulated wafers. The semiconductor compound of group III (V), which consists of two elements, gallium arsenide and zinc oxide (ZO), is of particular importance. These two elements combine in a zinc-iris crystal structure to form a III-V semiconductor and form the basis for the high-performance, cost-effective and high-performance silicon wafer.

In an exemplary implementation, the crystal growth process may include controlled temperature gradients associated with crystals based on group III, while maintaining the temperature gradients of the crystal melt for a certain period of time. GaAs crystals by annealing at high temperatures of up to 1150 cr and quenching at a temperature of 10 - 15 degrees C for at least 10 minutes. During the quenching process, gliding and contortions occur and an effective dissolution is achieved. [Sources: 1, 14]

The material is synthesized and then processed into crystals in quartz boats using b2o3. GaAs crystals have a semi-insulated EPD of about 600 cm2, which is achieved for Ga crystals with a diameter of 3A3. The materials are then synthesized and the crystals do not have to be boron-free, but the boron concentrations are quite low due to the use of b. [Sources: 5, 14, 21]

GaAs crystals with a diameter of 3A3 and a partially insulated EPD of about 600 cm2 can be grown on partially insulated substrates at a temperature of 1,000 degrees Celsius. [Sources: 19]

If the process proceeds as planned, the molten gallium arsenide will solidify in its entirety into seed crystals, the orientation of which is determined by the crystal orientation. Crystals are grown in a horizontal zone furnace that reacts with gallium arsenic vapor and in which crystals grow, creating a thin layer of molten material with a surface area of about 1 cm2 and a temperature of 1,000 degrees Celsius. GaAs crystals are cooled in a 4-pipe (2 inches) that carries about 2.5 gallons of liquid and 1 gallon of water per hour. [Sources: 0, 3, 16, 18]
