According to the substrate factory, Taiwanese customers are still mainly based on 2-inch PSS substrates. Although a small number of customers have begun to take 4-inch products, the proportion is still relatively low. In terms of shipments and revenue, the current PSS substrate accounts for only about 20% of the total sapphire substrate shipments. However, because the quotation is relatively high, it is nearly 50% from the perspective of revenue contribution.
The crystal power indicates that the PSS substrate has patent problems, so the company's current PSS substrate is not high in weight, and it is mainly used by customers.
Slightly expensive general sapphire substrate
Xinjing Drill said that the advantage of PSS substrate is that it can directly improve the brightness of LED chip, but it is still limited by the price of the sapphire substrate. Therefore, there is still a lot of room for growth in the use of Taiwanese customers. However, as LED lighting demand continues to increase, it is expected that PSS substrates will become mainstream products next year.
It is understood that the current average price of 2 inch PSS substrate is about 18 US dollars, which is twice as high as the sapphire substrate of the same size. Because of the high price, the chip factory has little intention to switch. However, the supply of PSS substrate has been enlarged. The price decline, coupled with increased brightness demand, will push up the penetration rate.
Some companies have indicated that the biggest problem with PSS substrates is patents. At present, the patents are mainly controlled by Niahia and other manufacturers. The patents held by the Japanese factory are processed on the sapphire substrate and polished to produce a regular surface. Floor. At present, Taiwanese manufacturers have also developed an illuminating layer with irregular surface, and can evenly increase the brightness of the LED chip, and can mass produce to circumvent the Japanese patent.
Taiwan factory actively researches and develops patents
Zhisheng said that there are two major problems in making a good PSS substrate. Apart from patents, the other is how to overcome the problem of uneven surface of the substrate. Zhisheng said that the current production of PSS substrates is mainly using step-wise equipment for exposure, but if the substrate is more than 4 inches, it is easy to cause exposure failure due to the substrate's warp, but the company has successfully developed nano-imprint technology. It is possible to directly produce an irregular pattern of PSS substrate while solving the problem of patent and substrate surface unevenness. 
Our products are widely used in air conditioner, refrigerantor, freezer, water dispenser, dehumidifier, cold storage, ice machine, ice cream machine, quick freezing machine, cooling machine, refrigeration equipment and so on.
The factory has advanced production equipment, standard production workshop. The pro-ducts are strictly enforced to the request of ISO9001:2008 quality control system, in order to guarantee the quality and the personal status of the product. We realize the importance of quality, our team pay much attention in every step in production, packing, and logistic as well. We strive for reaching a continuous growth and improvement.
PSS substrates are sought after by Xinjing Diamond, Zhisheng and other manufacturers are expected to benefit
Since illumination and backlights continue to increase the brightness requirements of LED chips, in order to effectively improve the brightness of LED chips, the use of PSS substrates is the fastest way. The Taiwanese industry said that the PSS substrate is about 30% brighter than the average sapphire substrate. It is expected that the penetration rate of the PSS substrate market will exceed 50% next year, including Xinjing Diamond, Zhaoyuan and the equipment factory Zhisheng.
