Breakthrough in the Sapphire Substrate Industry Dilemma

At present, the progress made by the global sapphire substrate industry is mainly reflected in three aspects.

First, the trend toward large-size sapphire substrate wafers is obvious. The proportion of 4-inch wafers and 6-inch wafers has been increasing. Some sapphire companies have begun to develop and test 8-inch wafers. This situation is mainly due to the fact that large-size substrate wafers are beneficial to MO epitaxial efficiency and cost reduction.

Secondly, the technology of crystal growth of more than 80 kilograms is maturing. Along with the trend of large-size sapphire substrate sheets, sapphire crystals have also developed to large kilograms. The weight of crystals has grown from the previous level of 30kg to 50kg to the current level of 80kg to 100kg. Similarly, the mass production of large kilograms of sapphire crystals will help reduce the cost of growth.

Finally, R is used in SOS radio frequency integrated circuits (RFIC) toward non-polar substrates. Its higher RF characteristics, smaller footprint and lower energy consumption can be widely used in smart phones, including smart phones. Consumer electronics products.

However, it is undeniable that the sapphire industry still faces greater development difficulties. Irrational project investment has led to poor crystal quality, low substrate quality, and low product competitiveness in some companies. However, the unordered competition between enterprises at low prices is also very obvious. Many companies are unsustainable and have appeared before. A wave shuts down and turns tide.

However, Tiantong believes that after the irrational development of the earlier period, the sapphire industry has gradually embarked on a healthy development path, and it is emerging in a mature attitude, launching new vitality and vitality. At present, Tiantong's production and sales are both prosperous and the supply pressure is obvious. The growth of market demand is believed to continue.

We are optimistic about the development of the sapphire industry for a long time and insist on innovation and development. We will focus on the development of large-size, high-quality, cost-effective sapphire crystals and substrates. In the next step, we will develop high-quality crystals of more than 100kg according to the market's technological development direction, further improve the efficiency, improve the process capability of the large-size substrates, and develop C-directional and non-polar substrates of more than 6 inches to develop SOS. Large-size sapphire substrate for high-end market demand. At the same time, it will further increase its production capacity and form an annual production capacity of 1.15 million 4-inch substrates in the future.
