Analysis of the Semi-annual Report of Hubei Dinglong Holding Co., Ltd.

Break through the core and key materials to create a big track innovation platform

Break through the core and key materials to create a big track innovation platform

The semi-annual report disclosed by Hubei Dinglong Holdings Co.
, Ltd.
on the evening of August 18 showed that the company achieved operating income of 1.
096 billion yuan in the first half of the year, a year-on-year increase of 35%
.

The semiconductor and integrated circuit industry is a strategic basic industry that the state encourages the development of
.

The independent production of upstream raw materials is critical .

It can be seen from the semi-annual report that the new business of Dinglong Optoelectronics Semiconductor Process Materials has three main highlights: CMP polishing pad has become an important new profit point; semiconductor cleaning solution project construction is progressing smoothly; flexible display substrate yellow polyimide (YPI) ) Continued sales of products, and breakthroughs were made in the research and development of new product panel photoresist (PSPI) and packaging ink (INK)
.

Breakthrough in CMP process core materials

　Breakthrough in　CMP process core materials CMP process core materials achieved breakthrough

CMP technology is internationally recognized as the only technology that can provide global wafer planarization, and is one of the important key processes in integrated circuit manufacturing
.

The key core materials of the integrated circuit CMP process technology mainly include polishing pads, polishing fluids, diamond discs and post-cleaning fluids, all of which are "chuck neck" materials for IC manufacturing in China

As the only CMP polishing pad supplier in China that fully masters the core R&D and manufacturing technology of the polishing pad, Dinglong shares disclosed in the semi-annual report that the company's polishing pad products achieved sales revenue of 104 million yuan in the first half of the year, an increase of 394.
35 over the same period of the previous year.
%, achieved a net profit of RMB 30,041,600, maintained a high growth trend, and continued to improve the gross profit level
.

The net profit of the product turned from a loss to a profit year-on-year .

　　The dominant position of Dinghui Microelectronics polishing pad products under Dinglong Co.
, Ltd.
has been initially established in the domestic market
.

In particular, the company's monthly sales of CMP polishing pads in July exceeded 10,000 for the first time, a nearly 50-fold increase compared to July 2019

　　"More importantly, the key raw materials of polishing pads have also achieved independent research and development and stable self-sufficient production
.

The goal of the next stage is to complete the localized production of all models of polishing pad products from mature processes to advanced processes

　　In terms of CMP cleaning fluids for copper processes, Wuhan Dingze New Materials Co.
, Ltd.
, a subsidiary of Dinglong Holdings, has developed products that are aligned with the international mainstream, and the product quality has reached the international advanced level of similar products
.

At the same time, in 2021, product verification and production capacity construction will be carried out simultaneously, and the first phase of the Wuhan headquarter's annual production line of 2,000 tons of cleaning fluid will be initially completed

　　The development of new display materials is in full swing

　The development of　new display materials is intensively developed.
The development of new display materials is intensively developed.

　　The new display industry is the leading pillar industry of the new generation of information technology.
In recent years, the scale of China's new display industry has grown rapidly, and mainstream technologies have also continued to make breakthroughs
.

Polyimide (PI), panel photoresist, and packaging ink (INK) are the key core materials for OLED displays

　　Dinglong began to develop PI materials for OLED displays in 2013.
It is the first domestic company to achieve mass production of YPI paste for flexible OLED display substrates, and the first domestic product to achieve full-process verification and online testing in the G4.
5&G6 generation line of panel manufacturers Enterprises that have passed and achieved ton-level sales
.

　　In the first half of 2021, Dinglong's YPI products obtained bulk ton-level orders, which helped the localization of YPI products
.

In terms of product verification, it has passed the formal quality system audit of major customers, and the major customer G6 line verification has been basically completed, and it has entered the stage of mass production

　　INK is used for device packaging to block water and oxygen and prevent oxidation of luminescent materials
.
Dinglong Co.
, Ltd.
has developed core process technologies such as INK core monomers and key formulas, and has established a printing performance test and evaluation system for inkjet printers of INK materials
.
In the first half of 2021, INK products have entered the pilot test stage, and the client-side sample test has begun; the research and development of new materials related to other new materials in the panel industry is also actively advancing
.

　　Create an innovation platform for key materials

　Create an innovation platform　for the key material track 　 Create an innovation platform for the key material track

　　Dinglong Co.
, Ltd.
is committed to building a platform company with various core "neck" innovative materials in the key big track field, and currently focuses on the fields of photoelectric imaging display and semiconductor process materials
.
Dinglong shares in-depth layout in the field of strategic advanced electronic materials, benchmarking against international high-end, focusing on material innovation, and building a first-class industry
.

　　In the past two decades, Dinglong Co.
, Ltd.
has built seven technology platforms in the material field.
The technology platform model applies the company’s successful research and development of high-end materials technical experience to new projects, and creates a direct, professional and efficient "old with new".
Cultivate a growth environment to allow new projects and new talents to grow simultaneously on the technology platform
.

　　Dinglong Co.
, Ltd.
owns innovation platforms such as the National Enterprise Technology Center, Postdoctoral Research Workstation, Hubei Engineering Research Center, and Jiangcheng Laboratory
.
As of June 30, the company has 617 authorized patents, including 213 invention patents, 56 design patents, 350 utility model patents, and 72 software copyrights and integrated circuit layout designs
.

　　According to reports, in the first half of this year, Dinglong’s R&D investment reached 116 million yuan, a significant increase of 60.
59% over the same period last year.
Although it affected short-term profits to a certain extent, it laid a solid foundation for the company’s long-term development
