Hangzhou Yusheng Electronic Technology

Hangzhou Yusheng Electronic Technology Co., Ltd., operating under the brand name Microparity, is a specialized semiconductor design firm established in August 2017. The company was founded by a team of returning overseas PhDs in physics, electronics, and optics, and was among the first enterprises incubated at the Hangzhou National "Core Fire" Innovation Base. The leadership team possesses deep domain expertise; Founder, Chairman, and Chief Scientist Dr. Shen Wei holds a Ph.D. from Heidelberg University and previously led sensor development at the Kirchhoff Institute for Physics. Co-founder and CEO Xinjiā Shěn, and CTO Dr. Hesong Xu, who earned his Ph.D. from the University of Trento and was a visiting scholar at Stanford, also bring extensive experience from major European optoelectronic semiconductor projects and companies like AMS, where they gained expertise in mass-producing single-photon sensors.

Microparity focuses on the design and development of single-photon sensitive devices based on direct Time-of-Flight (dToF) technology. The firm's core business revolves around creating high-precision, custom-designed integrated circuits and related system solutions for a variety of high-tech industries. The product portfolio is centered on three main categories: Single-Photon Avalanche Diodes (SPAD), Silicon Photomultipliers (SiPM), and Application-Specific Integrated Circuits (ASIC) that process the signals from these sensors. SPADs are high-sensitivity detectors capable of measuring the energy and timing of a single photon, while SiPMs are arrays of avalanche diodes that offer high gain and sensitivity.

The company's business model is to supply these advanced semiconductor components to clients in innovative fields. Key markets include automotive LiDAR, where its sensors provide high-precision ranging for autonomous driving, and medical imaging, particularly for PET detectors, where its ASIC chips achieved mass production in 2021. Additional applications for its technology are found in consumer electronics with 3D sensing capabilities, industrial inspection, high-energy physics, and aerospace. The company has received recognition as a National High-tech Enterprise and has secured multiple rounds of funding, including a Pre-A+ round in November 2023, to fuel its growth and R&D efforts.
