Congratulations to the YW MEMS for completing the tens of millions of Pre-A round of financing

YW MEMS (hereinafter referred to as YW MEMS) completed in November a tens of millions of Pre-A rounds of financing led by Zhiyou Jinmiao Fund, Kaifeng Venture Capital, and Dexun Investment. This round of financing is mainly used for the construction of pilot and mass production test plants for MEMS liquid flow sensors.

The in-situ chip was established in 2015. In 2018, it received an angel round of financing led by Zhongke Chuangxing and co-invested by Chengcun Capital. In-situ chips are mainly engaged in the research and development, production and sales of silicon nitride film products and new medical MEMS (Micro Electro Mechanical System) chips and modules. In-situ chips now have a variety of standardized products such as synchrotron radiation/SEM silicon nitride film panes, TEM silicon nitride film panes, and in-situ liquid chips. Among them, the synchrotron radiation/SEM silicon nitride film pane has the characteristics of high cleanliness, high X-ray transmission, low stress, high strength and uniform film thickness, and is suitable for high temperature (~1000℃) experiments and different pressure environments Test; TEM silicon nitride film pane adopts low stress technology (<250MPa), the silicon nitride film is thin and not easy to be damaged, and has a variety of standard products such as single pane, multi-pane and microporous pane, applicable For all TEM sample rods; the in-situ liquid chip can realize high-resolution in-situ TEM liquid observation with a resolution of more than 1nm.

In addition, in-situ chips have mastered more than 40 leading MEMS technologies, and have independent R&D and independent tape-out production capabilities for the entire process of chip design, process development, tape-out production and testing.

At this stage, the medical industry has an urgent need for intelligent upgrades. It needs to monitor the real-time flow of various liquids entering and leaving the human body, such as liquid medicine infusion and urine collection. However, imported MEMS sensors are too expensive to be widely used.

In-situ chip CEO Ma Shuo said: "In-situ chips have more than 4 years of technology and resource accumulation on the medical MEMS track. Core products have great technical and market advantages in terms of accuracy, size, and price. These advantages are conducive to the entry of in-situ chips into the Chinese market, the realization of import substitution, and the widespread popularity."

The in-situ chip has its own senior MEMS process tapeout team, which can complete MEMS chip design, tapeout and testing by itself. On this basis, the in-situ chip independently developed a medical MEMS liquid flow and bubble sensor MEMS insulin micropump. At present, the medical MEMS liquid flow and bubble sensor is in the sample delivery stage for prototype customers; the prototype of the MEMS insulin micropump product has been successfully developed and the prototype is being developed.

Among them, the medical MEMS liquid flow and bubble sensor is mainly used for accurate liquid flow measurement of medical equipment. It can achieve a liquid flow measurement accuracy of ±5% within a range of 10μl/min~10L/min. The downstream customer is an anesthesia pump , Chemotherapy pumps and analgesic pumps and other medical device manufacturers, adding this sensor can greatly improve the output accuracy of medical devices, thereby improving the efficacy and patient experience.

The MEMS insulin micropump module is mainly used for high-precision supply of insulin, which can achieve ±3% insulin injection under different temperature and pressure conditions. It is understood that the module has received sample invitations from many medical device companies. These medical device manufacturers hope to replace their current micro motors with MEMS micro pump modules, thereby launching a low-cost, high-precision attached disposable Insulin Pump.

With the changes in the structure of my country's population aging, people's health care problems have become more important than ever. In vitro diagnostics, drug research, patient monitoring, drug delivery methods, and implantable medical devices are constantly innovating. Nowadays, how to improve product performance, reduce product cost, and reduce product size has become an urgent problem for many medical and health companies. The emergence of MEMS has just achieved a qualitative breakthrough, bringing unprecedented convenience and experience to medical applications.

In the future, in-situ chips will continue to improve the technology and performance of existing products based on the company's design, process and industrial resource advantages in the medical MEMS field, bring new medical MEMS products that break the monopoly to the market, and further develop different models of products To meet the diversified needs of the medical industry, we will fully deploy the medical MEMS field.
