In order to repay investors, the company plans to distribute a cash dividend of 2.77 yuan (including tax) to all shareholders for every 10 shares based on the total share capital registered on the date of equity distribution. As of March 31, 2022, the total share capital of the company is 109210000 shares. Based on this calculation, the total cash dividend to be distributed is 3025117000 yuan (including tax), accounting for 30.60% of the net profit attributable to the shareholders of the listed company in the consolidated statements. The company does not convert capital reserve into share capital and does not give bonus shares. If the total share capital of the company changes before the equity registration date of equity distribution, the company plans to keep the total distribution unchanged and adjust the distribution proportion per share accordingly.
The profit distribution plan of the company in 2021 has been deliberated and approved at the 7th Meeting of the first board of directors of the company, which needs to be implemented after deliberated and approved by the 2021 annual general meeting of shareholders of the company. 8、 Whether there are important matters such as special arrangements for corporate governance □ applicable √ not applicable IX. risk statement of forward-looking statements √ applicable □ not applicable

The reporting period refers to January December 2021
Yuan and 10000 yuan refer to RMB yuan and 10000 yuan
Chip, integrated circuit and IC refer to the integrated circuit, which is a kind of micro electronic device or component. The required electronic components such as transistors, resistors, capacitors and inductors are connected according to the requirements by using the corresponding process, and made on the same wafer substrate to realize the electrical circuit of specific functions. IC is the English abbreviation of integrated circuit, and chip is the common name of integrated circuit
Wafer Factory refers to the wafer foundry, which refers to the enterprise specially responsible for chip manufacturing
Wafer refers to circular silicon or compound crystal semiconductor materials, also known as wafers, wafers and wafers, used to manufacture integrated circuits
Sealing and testing refers to the abbreviation of “packaging and testing”; “Packaging” refers to the installation of the shell for the chip to realize the functions of fixing, sealing, heat conduction, shielding and protecting the chip; “Test” refers to testing whether the function and performance indexes of the encapsulated chip meet the requirements
Mask, also known as mask, photomask or reticle, is a mold for producing wafers (wafers).
The mask is produced according to the integrated circuit layout designed by the chip design company. A set of mask usually has several to dozens of layers according to the complexity of the chip. The wafer manufacturer produces the wafer according to the mask
In order to verify whether the integrated circuit design is successful, it must be streamed, that is, from a circuit diagram to a chip, to check whether each process step is feasible and whether the circuit has the required function and performance. If the chip is successfully streamed, the chip can be manufactured on a large scale; On the contrary, it is necessary to locate the cause and carry out corresponding optimization design – the above process is generally referred to as engineering trial flow. Mass production after the success of engineering trial production is called mass production
