Mixed-signal integrated circuit developer Beijing Dongwei Century Technology Co., Ltd. today announced the successful launch of the first domestic 32-channel weak current signal amplifier. This product, numbered EMT1010, is a large-scale digital-analog mixed integrated circuit, mainly targeting various industrial and medical electronic applications, such as security inspection systems, medical CT scanning, infrared detection, industrial non-destructive testing, and photoelectric conversion. This chip is the first domestic high-integration, high-performance, multi-channel weak signal amplification chip that is resistant to harsh environments. With the acceleration of China's social development and infrastructure construction, the market for system equipment used in various industrial and medical applications is growing rapidly, but many system developers in these fields have long been constrained by foreign technology, making it difficult to achieve chip-level system development and innovation. Through in-depth exchanges with domestic system manufacturers, Beijing Dongwei proposed the concept of replacing similar foreign products with innovation. The EMT1010 launched this time is based on innovative clock delay technology, which can simultaneously amplify and output weak current signals (pA level) generated by X-ray, infrared, and other radiation sensors through 32 channels, and after A/D conversion, achieve fast computer imaging. In order to bring the highest cost-performance ratio to system manufacturers, Beijing Dongwei utilized its analog technology advantages and adopted standard CMOS process technology; at the same time, in response to the diverse application requirements in the field of weak current signal detection, it formulated a product strategy of using high integration, multi-channel, and strong environmental adaptability to meet different application needs. Therefore, the EMT1010 can significantly improve the cost-performance ratio of analog front-end functional modules in security inspection equipment, photoelectric and infrared equipment applications. The EMT1010 has good amplification linearity, fast response capability, and optimized output noise, and it adopts a QFP64 package. Recently, BOE Technology Group Co., Ltd.

Based on the complete set of special process 12-inch integrated circuit production line / On June 17, the Shanghai Stock Exchange officially accepted the IPO application for the Science and Technology Innovation Board of Suzhou Dongwei Semiconductor Co., Ltd. (hereinafter referred to as: Dongwei Semiconductor). The prospectus shows that Dongwei Semiconductor is a technology-driven semiconductor enterprise mainly engaged in the research and development and sales of high-performance power devices, with products focusing on medium and high power application fields related to industry and automobiles. During the reporting period, Dongwei Semiconductor's main products include the GreenMOS series high-voltage super junction MOSFET, SFGMOS series, and FSMOS series medium and low voltage shielded gate MOSFET. The company's products are widely used in industrial-level application fields represented by new energy vehicle DC charging piles, 5G base station power supplies and communication power supplies, data center server power supplies, and industrial lighting power supplies, as well as consumer electronics application fields represented by PC power supplies, adapters, TV power boards, and mobile phone fast chargers. At the same time, the company continues to innovate technologically and has further developed new products such as super silicon MOSFET and TGBT. Dongwei Semiconductor's IPO application for the Science and Technology Innovation Board was accepted, raising 939 million yuan to increase power device capacity / Jiwei.com reported that with the rapid penetration of dual cameras, triple cameras, and multiple cameras in global smartphones, downstream camera module manufacturers are also in strong demand. For example, O-Film's camera module shipments increased from 551 million units in 2018 to 553 million units in the first three quarters of 2020, Sunny Optical's shipments increased from 423 million units in 2018 to 593 million units in 2020, and Q Technology's shipments increased from 371 million units in 2018 to 484 million units in 2020. The supplier of the above manufacturers and the main producer of optical filters, Hubei Dongtian Micro Technology Co., Ltd. (hereinafter referred to as: Dongtian Micro), also saw its production capacity increase from 216 million pieces in 2018 to 556 million pieces in the first three quarters of 2020. Relying on major customers, Dongtian Micro's performance has grown rapidly, but its revenue mainly relies on infrared cut-off filters, and its revenue structure is relatively single. Moreover, product prices are greatly affected by changes in the smartphone market, causing a sharp drop of 76% in net profit growth in 2018. There are still concerns on the road to listing / With the rapid penetration of dual cameras, triple cameras, and multiple cameras in global smartphones, downstream camera module manufacturers are also in strong demand.
