Dedicated to the Core | The Importance of Silicon in the Semiconductor Field

Semiconductors are the core of the information technology industry and a strategic, foundational, and pioneering industry that supports economic and social development and ensures national security. The technological level and development scale of semiconductors have become one of the important indicators of a country’s industrial competitiveness and comprehensive national strength.

With the advancement of technology and its continuous expansion, the emergence of new fields such as 5G, the Internet of Things, artificial intelligence, and smart driving has brought new opportunities to the semiconductor industry, leading to a deeper understanding of the semiconductor industry by society.

Silicon (Si) is a very common element, appearing as a black-gray crystal or powder. It rarely occurs in its elemental form in nature but is widely found in rocks, gravel, and dust as complex silicates or silicon dioxide. Silicon has unidirectional conductivity and is an important semiconductor material, formerly known as silicon.

First, we must understand that semiconductors ≠ chips, but chips are the top products in the semiconductor field and the crystallization of technology. In the field of semiconductor materials, silicon ≠ sand, and there is often a misconception that “sand can be used to make chips.” In fact, this is not the case. The main chemical component of sand is silicon dioxide, while the basic material for making chips is silicon, which are fundamentally different. Silicon material for chips can be prepared by reducing silicon dioxide, and to prepare the substrate material for chips, polysilicon material needs further processing to produce single-crystal silicon material for chips.

Why choose silicon as the raw material for semiconductors:

• Silicon is abundant and easily obtained;

• Silicon purification technology is mature, and the production cost is low;

• The stability of silicon and its common derivatives, with a melting point of 1412 degrees, ensures compatibility with the high-temperature processes of integrated circuit production;

• The perfect fit and complementarity of the physical properties of silicon and its derivatives;

• Silicon itself is a non-toxic and harmless substance, and many common stones contain silicon dioxide (SiO2).

Ningxia Dunyuanjuxin Semiconductor Technology Corporation, based in the semiconductor industry chain, provides supporting consumables for semiconductor manufacturing. It is a high-tech enterprise with strong semiconductor industry experience and advanced production management concepts and has quickly grown into a leading enterprise in the domestic semiconductor silicon component industry. The silicon semiconductor company specializes in the R&D, production, and sales of semiconductor quartz crucibles, semiconductor silicon component materials, and semiconductor etching silicon components, covering high-purity, high-quality quartz crucibles for semiconductor and solar use; semiconductor-grade large-diameter silicon rods, columnar polycrystalline silicon ingots, silicon wafers, silicon tubes, precision silicon products, and other single and polycrystalline silicon component products.

After years of development, the company can provide silicon parts raw materials of various specifications from 12-24 inches. In 2019, it successfully developed φ500mm and φ560mm single-crystal silicon rods; in December 2020, it successfully developed and produced 620mm high-quality large-size silicon component crystal rods, becoming the first manufacturer in the world capable of producing single-crystal silicon rods with a diameter of over 600mm. Today, the company has a class 100 super cleanroom facility and uses the most advanced production and processing equipment from the United States, Japan, and China. The products are highly precise and clean, have been certified by mainstream semiconductor equipment manufacturers, and are widely used in the mass production process of mainstream semiconductor silicon wafers, exported to semiconductor-developed countries such as the United States, Germany, Italy, Finland, Japan, and South Korea.

Practicing long-term commitment and never stopping technological innovation, Shield Source Polycore always adheres to a specialized development path, deeply cultivates the semiconductor industry, breaks foreign technology blockades, solves “bottleneck” problems, and contributes to the localization of core consumables for semiconductor equipment, contributing “core” strength.
