WELDED STAINLESS STEEL CYLINDERS FOR ULTRA-HIGH PURITY MATERIALS

Welded Stainless Steel Cylinders for Ultra-High Purity Materials (Gases)

A. MO Source

MO source stands for metal-organic source, which is a high-purity compound formed by the combination of metal elements and organic ligands. Its purity directly affects the performance of downstream products. The main products include trimethyl gallium (TMGa), triethyl gallium (TEGa), trimethyl indium (TMIn), bis(dimethylamino)silane, methylbis(dimethylamino)silane, trimethylaluminum (TMAl), gallium trichloride, tri(dimethylamino)silane, tetramethylsilane, bis(tert-butylamino)silane, diethylzinc, hexachlorodisilane, chlorosilane, tetra(dimethylamine)titanium, ethyl orthosilicate, etc.

Main uses of MO sources

1. Semiconductor field: chemical vapor deposition (CVD) and other processes, phase change memory, semiconductor lasers, radiofrequency integrated circuit chips, etc.

2. Optoelectronics field: manufacturing of devices, such as light-emitting diodes (LEDs) and laser diodes.

3. 5G communication technology.

4. New energy field: preparation of efficient solar cell materials.

5. Smart devices and Internet of Things (IoT) field.

B. Precursor

Precursor refers to the intermediate material form between raw materials and the final product, requiring conversion through calcination, deposition, or other reactions.

a. Classification of precursors

1. High-K dielectric precursors:‌ Feature thermal stability, process reliability, and volatility to reduce device leakage and improve yield.

2. Silicon oxide / nitride precursors:‌ Used in double lithography and sidewall spacers to protect integrated circuit gate properties.

b. Main application areas of precursors

1. Semiconductor manufacturing

Chemical vapor deposition (CVD), atomic layer deposition (ALD), epitaxial growth, etching, ion implantation doping, cleaning, etc.

Metal and metal nitride precursors are used for capacitor electrodes, gate transition layers, isolation materials in semiconductor storage and logic chips, and phase change materials in phase change memory.

2. Lithium-ion battery

It is composed of nickel, cobalt, manganese (or aluminum), which is processed to form positive electrode materials to improve battery energy density and safety.

3. Other fields

Ceramic / glass: Improve sintering performance.

OLED packaging: Moisture barrier for extended device lifespan.
