Jiwei Network News, on April 19, Xindao Technology released its 2021 annual report, saying that the company achieved operating income of 475.6495 million yuan, an increase of 29.13% over the same period of the previous year; achieved a net profit attributable to the owners of the parent company of 114.5263 million yuan, an increase of 54.42% over the same period of the previous year; and the net profit attributable to the owners of the parent company after deducting non-recurring gains and losses was 108.4883 million yuan, an increase of 51.51% over the same period of the previous year.
Chip Guide Technology said that thanks to the improvement of semiconductor prosperity, as well as the continuous introduction of new products and the optimization of product structure, the sales volume of the company's main product TVS increased, and the sales of other products MOS and IC also rose rapidly.
The main business of core guide technology is the research and development and sales of power semiconductors, the company's power semiconductor products include power devices and power ICs two categories, the product application field is mainly based on consumer electronics, a small part of the application field in the field of security, network communications, industrial field.
In terms of TVS products, the ultra-low capacity value (
In recent years, in the consumer electronics market, especially in the field of smart portable and wearable products such as mobile phones, tablet computers, and TWS, in order to improve the endurance and reduce the loss of electronic components, the working voltage of the chip has been continuously reduced, which also makes the chip extremely sensitive and easily damaged. The ESD products with deep fallback features extremely low clamping voltages, while also having strong current discharge capabilities, providing the best protection solution and making it feasible for the chip to develop towards lower losses and lower operating voltages.
In terms of MOSFET products, MOSFET products with ultra-low on-resistance, low switching losses and fast reverse recovery functions have been successfully developed and verified by end customers, and have been mass-produced; at the same time, MOSFET products with ultra-low on-resistance and ultra-low gate charge have completed projects and have been developed. The company's MOSFET products are used in mobile phones, tablet computers, TWS, PD fast charging, notebook computers, power tools, BMS, motor control and other fields, which can provide lower losses and higher switching frequencies.
In terms of Schottky products, an optimized low forward pressure drop groove MOS structure Schottky diode project, some of which have been successfully developed and validated in multiple customers. The product not only reduces losses, but also increases the sustainable conduction current, and has an ultra-small size, which is extremely versatile.
In terms of the third generation of semiconductor GaN products, the third generation of semiconductor 650V GaN HEMT project, a number of products have been successfully developed and verified in multiple clients. GaN products have the characteristics of high power density, high speed and high efficiency, and are significantly better than traditional semiconductor materials such as Si and GaAs in terms of breakdown electric field, intrinsic carrier concentration, and irradiance resistance, so they have broad application prospects in the fields of fast charging sources, 5G communications, and smart grids.
In terms of power IC research and development, with the company's third-generation semiconductor 650VGaNHEM device high integration driver chip, in 2021 successfully passed the tape-out verification, is expected to be mass production in 2022, can be widely used in high-power smart phone chargers and large-energy density LED lighting and other products, is conducive to the miniaturization of terminal products; BASED ON the mobile phone platform CPU DCDC series products, with high current and high efficiency characteristics, 2021 has completed the tape-out verification, It is expected to enter mass production in 2022; high-current half-voltage charging IC products, with high charging efficiency characteristics, is an important solution for high-power charging in the current mobile phone tablet products, has entered the tape-out verification stage, and is expected to enter mass production at the end of 2022; at the same time, it has high precision, high efficiency, high stability step-down high-voltage high-current series and buck-boost high-current series products, which are suitable for consumer electronics, industrial and automotive application terminals, and are also put on the development and design agenda in 2021.
