Dinglong Co., Ltd.: Tungsten polishing liquid products have obtained orders from domestic mainstream wafer fab customers
According to the micro-net news, on November 7th, Dinglong Co., Ltd. announced that the company's holding subsidiary Wuhan Dingze New Material Technology Co., Ltd. (referred to as "Dingze New Material") polishing liquid product marketing is progressing smoothly. After the polishing liquid entered the ton-level procurement stage and the dielectric material polishing liquid products continued to obtain orders steadily, the company's tungsten polishing liquid products recently received a purchase order from a mainstream domestic wafer manufacturer for the first time. The purchase quantity is 20 tons.
The announcement shows that this polishing liquid is benchmarked against an overseas competing product, which can fully meet the customer's use requirements and some performances are better than those of overseas competing products. This polishing liquid is used in a special process, which requires a selectivity ratio for the grinding of various thin films. It is a very difficult tungsten polishing liquid. Under the circumstance of being "stuck" by overseas suppliers and no other domestic alternative supplier's products can meet this process requirement, the company's products successfully passed the client test and obtained a ton-level purchase order.
Dinglong Co., Ltd. pointed out that at present, the company's other process CMP polishing liquid products cover many customers across the country and enter the key verification stage, laying the foundation for the rapid increase in volume in the future. In terms of production capacity construction, the first phase of the Wuhan headquarters factory has an annual output of 5,000 tons of fully automated polishing fluid production lines that can meet customer orders. The capacity construction of the Xiantao CMP polishing liquid expansion project with an annual output of 20,000 tons and the supporting expansion project of abrasive particles is in progress.
It is reported that starting from the core raw material abrasive particles upstream of the CMP polishing liquid, the company has deployed more than 30 kinds of CMP polishing liquid products in a variety of process series. Among them, the silicon oxide polishing liquid products have continued to receive orders steadily, and the aluminum process polishing liquid has entered the ton-level procurement stage. Other CMP polishing liquid products covering many customers across the country have also entered the key verification stage, laying the foundation for the accelerated production volume next year.
