On April 7, SZDB Technology issued an announcement in 2020, the company plans to issue a total of no more than 164,376,000 shares (including the number), and the total funds raised will not exceed 1.78 billion yuan, used for quantum carbon compound thick film industrialization projects, new colorless CPI film / (Colorless Polyimide Film) project, quantum carbon compound semiconductor film R & D project and supplementary working capital project.
SZDB Technology stated that the overall goal of this fund-raising investment project is to mass-produce quantum carbon compound thick films, Colorless Polyimide Film, and research and development of quantum carbon compound semiconductor films. basis.
At present, SZDB Technology has mastered the core technology and process in the field of PI film, successfully mass-produced microelectronic grade PI film, and realized the independent matching of the key raw material PI film of the existing FPC, COF and other products. On this basis, the company continued to extend along the PI film industry chain, broke through the core processes of deep processing of PI films such as carbonization and black lead, and successfully developed a thick film of quantum carbon compounds. This fund-raising investment project aims to accelerate the industrialization of quantum carbon compound thick films. Quantum carbon compound thick film is a chemical microelectronic grade polyimide thick film (130μm / 140μm / 150μm / 160μm / 170μm) independently developed by the company, which is processed by carbonization, black lead and other processes. The thin-film product formed afterwards has a two-dimensional large molecular weight superlattice network structure. Quantum carbon compound thick film has the characteristics of high density, high van der Waals force, high thermal conductivity, high heat storage function, high average heat effect, no dust, no ion migration, etc. It can be used as a 5G smart terminal, 5G base station, automotive electronics Heat dissipation materials, flexible display substrates, flexible solar cell substrates, electrode pole piece materials for solid state batteries, and high-frequency electronic circuit substrates have high added value and have broad market demand.
In addition, the implementation of the quantum carbon compound thick film industrialization project on the one hand can expand the emerging application market of PI film and enhance the added value of the company's products, on the other hand, it can reduce the risk of FPC and COF product business fluctuations, making the company's business more For soundness.
In terms of CPI films, as Samsung and Huawei have successively launched foldable phones, the flexible OLED industry is showing rapid development, and there is an urgent demand for transparent PI films of upstream materials. The company has achieved mass production. SZDB Technology said that this fundraising will continue to invest in the R & D and pilot testing of CPI membranes, improve the company's CPI membrane manufacturing technology and product quality, keep up with the international leading level, seize the first-mover advantage to enter the customer supply system, and enhance the company's technical strength And market influence.
In addition, the company uses the original TPI preparation process, nano metal doping, hybridization, ion exchange and ion implantation process, the nano monoclinic crystal in the film can be transformed into a tetragonal crystal, forming a hexagonal lattice layered structure With a superlattice function, a quantum carbon compound semiconductor film is obtained. The quantum carbon compound semiconductor film has a wide band gap, high thermal conductivity, high flexibility, high breakdown electric field, high electron saturation rate, high radiation resistance, high and low temperature resistance, conductivity and controllable carrier concentration, etc. Various characteristics, very suitable for the production of a new generation of flexible high-temperature, high-frequency, radiation-resistant high-power devices, is expected to be widely used in ultra-high frequency analog transistors and nano sensors in the future.
The quantum carbon compound semiconductor film is a new type of compound semiconductor material, which has unique characteristics compared with other compound semiconductor materials in terms of high mobility, nano size, flexibility, permeability and controllability of conductive properties, and is expected to become a comprehensive New compound semiconductor materials with better performance. Through the research and development of quantum carbon compound semiconductor films, the company has expanded from a polymer material to a compound semiconductor material in the field of new materials, which has great strategic significance.
SZDB Technology said that after the completion of this non-public offering, the quantum carbon compound thick film, new transparent PI film and existing PI film will rapidly develop and expand as the company's new material business segment. COF and other electronic device products form a good linkage effect, which has a positive role in promoting the company's strategic planning.
