MOCVD application

MOCVD is a thin-layer single crystal material that uses organic compounds of group III and group II elements and hydrides of group V and VI elements as crystal growth source materials, and performs vapor phase epitaxy on the substrate by thermal decomposition reaction to grow various III-V and II-VI compound semiconductors and their multicomponent solid solutions. Generally, the crystal growth in MOCVD system is carried out in the cold wall quartz (stainless steel) reaction chamber with H2 under normal pressure or low pressure (10-100torr). The substrate temperature is 500-1200 ℃, and the graphite base is heated by RF induction (the substrate is above the graphite base). H2 bubbles through a temperature controllable liquid source to carry organometallic substances to the growth area.


Our advantages


               


-It has a wide range of applications, and can grow almost all compounds and alloy semiconductors.

Raw material
Starting from raw materials, it is very prominent in the stability and consistency of products. Identify different brands of raw materials and mark the batch number. And each batch of raw materials shall be sampled, inspected and archived. Ensure the traceability of each finished product.
From powder to finished products, GeMei strictly controls every process in the production process
Blend
Ensure that the materials in the milling and mixing process can be fully stirred and evenly distributed to ensure the consistency of the internal organization of the product.

Extrusion
The pressing process is the process of powder blank forming. The pressing of powder is completed by isostatic pressing equipment to make its internal structure uniform and dense.

From powder to finished products, GeMei strictly controls every process in the production process
After the metal powder is pressed by isostatic pressing, it is heated at a temperature lower than the melting point of the main components to make the particles connect, so as to improve the performance of the product, which is called sintering.

Sinter

Machining
Through turning, milling, cutting, grinding and other mechanical processing procedures, it can be processed into various customized sizes of customers, and ensure that the internal organization of tungsten and molybdenum materials is tight, stress free and free of holes

From powder to finished products, GeMei strictly controls every process in the production process
Quality testing
Starting from raw materials, quality inspection and control, as well as quality inspection and sampling inspection of each process, continue to ensure the process quality control of each process of the product.
