The Shenzhen company mass-produces the world's first miniature spectral chip
The reporter recently learned from Shenzhen Haipu Nano Optical Technology Co., Ltd. (HyperNano, referred to as Haipu) that at the beginning of 2022, the company announced that it officially took the lead in mass production of the first generation of micro-hyperspectral MEMS (Micro-Electro-Mechanical Systems, Micro-Electro-Mechanical Systems). System) chips, hyperspectral industrial cameras and hyperspectral camera modules are coming to the market soon.

It is reported that based on the micro-hyperspectral MEMS chip technology, the hyperspectral imaging module launched by Haipu has reached the world's leading level in professional technical indicators such as wavelength accuracy, shooting speed, spatial resolution, half-peak width, and field of view angle. The spectroscopic camera has been shrunk by a factor of nearly 1,000, making it the smallest hyperspectral camera model in the industry.
Semiconductor Veteran Shenzhen Entrepreneurship Crosses the "Valley of Death"
Huang Jinbiao, founder and CEO of Haipu, introduced that the company was founded in January 2019 with the mission of "spectral core vision, perception beyond the limit", focusing on the design and development of hyperspectral imaging technology.

Huang Jinbiao graduated from Nankai University with a major in microelectronics. He has more than 20 years of experience in semiconductor technology and market. He has served as a senior executive of many semiconductor companies and has strong experience in system development and market development. Expert of Shenzhen Micro-Nano Promotion Association
The Haipu R&D team has nearly 20 years of experience in chip design and process manufacturing in the MEMS field. The core members of the team include a number of top MEMS experts and Shenzhen Peacock talents.
In March 2022, Haipu completed tens of millions of yuan in Series A financing. Investors include Kunlun Capital, Yuanfang Capital, and Wanxin Capital.
According to industry insiders, MEMS chips are most commonly used for sensing functions, which are somewhat similar to human sensory systems in the entire large information system. In terms of industry, Europe and the United States are the birthplaces of the MEMS industry, technology and products, and are in a leading position in the world. China's MEMS industry started late, and the MEMS industry is still in its infancy. my country is not only in the performance indicators such as accuracy and sensitivity. There is a huge gap abroad, and the scope of application is mostly limited to the low-end fields. Therefore, there is a saying that it is difficult to start a business with a chip, and it is even more difficult to start a business with a MEMS chip. However, although my country's MEMS sensor manufacturers face many challenges, there is huge room for domestic substitution in upstream design, midstream manufacturing, downstream packaging and other fields.

Because of being in the high-end industry of MEMS industry, Haipu has experienced the "Valley of Death" test faced by high-tech start-up companies from the early 3 years of establishment, that is, various challenges from technology research and development to product mass production.
"No matter how advanced the technology of a start-up company is, it must be turned into an engineered and marketable product. There are many pitfalls in this process. Only by stepping forward can the technology have commercial value." Huang Jinbiao said.
Huang Jinbiao introduced that when Haipu reached the end of last year, mass production of the most core technology chips began. At the same time, the relevant modules for applying the chip to the camera have also been prepared, which is equivalent to the company's biggest threshold for a start-up company of technical engineering products, which has already passed.
Filling the gap in the field of domestic micro-hyperspectral MEMS chips
Speaking of the technology of sea spectroscopy, first of all, it is necessary to popularize the spectroscopy technology.
Spectroscopy began with Newton, a British scientist, and is an important way for humans to perceive the world with the help of light. Different elements and their compounds on the earth have their own unique spectral characteristics. Therefore, the spectrum is regarded as the composition information that can distinguish substances.
One of the biggest features of spectroscopy is the study of the interaction between light and matter. The composition of an object can be obtained through physical methods, and it can be detected in a non-contact and non-destructive manner. Typical such as astronomical objects, high-temperature objects, discharge gases... At the molecular and atomic level, the material is analyzed and studied, mainly using the spectral method. For example, humans use spectroscopic cameras to photograph the surface material of distant planets.
Principle of Miniature Hyperspectral Photo by Nanfang + Li Ronghua
Huang Jinbiao introduced that hyperspectral imaging technology combines imaging technology with spectral technology to obtain continuous, narrow-band image data with high spectral resolution. The principle is to combine imaging technology with spectral technology to obtain the spectral information at each spatial position while detecting the two-dimensional spatial information of the target, so as to realize the direct detection of material components. The material spectral information has fingerprint characteristics, that is, different. The substances have different spectra, so hyperspectral imaging provides a new path for the perception, identification and analysis of substances in machine vision, and is the next generation of revolutionary visual imaging technology after 2D and 3D vision technology. In 2019, after Haipu was established in Shenzhen, it started the R&D, design and tapeout of the first miniature hyperspectral MEMS chip. At the beginning of 2020, Haipu announced the official mass production of the first generation of micro-hyperspectral MEMS chips, filling the domestic gap in the field of micro-hyperspectral MEMS chips.
Traditional spectral imaging equipment is generally assembled by hand, which has problems such as large size, high price, and inability to mass-produce. The Haipu nano-optical micro-hyperspectral MEMS chip has performance advantages such as high spatial resolution and high light transmittance, which solves the problem of spectral imaging equipment volume. , cost and other issues; the mass production of chips can also effectively reduce the inter-stage difference of hyperspectral imaging equipment, and realize the automatic assembly of chips to the whole machine.
As a result, Haipu has made a breakthrough in the special process of MEMS, and solved the industry problems of industrialization, low cost and mass production of hyperspectral imaging. The research and development capabilities cover chip design, optical modules, product cameras, algorithm research and development, complete Hyperspectral full-chain technologies such as application solutions can provide one-stop hyperspectral imaging solutions for customers in multiple fields around the world.
"Traditional spectral imaging equipment is a large instrument; Haipu's camera module is only the size of a fingernail, and it is cheaper. No matter in terms of size, price, and convenience, it has crossed the threshold for civilian use. to the world's leading position." Huang Jinbiao compared.
