Unit Introduction

FreeSpirit Instruments (Shanghai) Co., Ltd. (“FreeSpirit Instruments”) is a high-tech innovative enterprise specializing in the research, development, and manufacturing of precision surface metrology equipment. Built upon its independently developed technological foundation, the company has successfully launched flagship products including domestic Atomic Force Microscopes (AFM), White Light Interferometers (WLI), and integrated AFM–WLI systems.
The core team members are all graduates of the Department of Precision Instruments at Tianjin University, with decades of technical expertise and hands-on experience in advanced metrology. Leveraging a collaborative structure of “Shanghai Headquarters + Tianjin R&D + Suzhou Manufacturing,” FreeSpirit Instruments has established a complete closed-loop system from technological innovation to industrial implementation. The company is committed to providing high-performance, stable, and reliable domestic precision metrology solutions for cutting-edge fields such as scientific research, compound semiconductors, Micro-LED, and next-generation display technologies.
In recent years, gallium oxide, as a strategic frontier in ultra-wide bandgap semiconductor materials, has demonstrated significant potential in high-voltage power devices and deep ultraviolet optoelectronics. However, from substrate preparation to epitaxial growth, gallium oxide faces stringent process challenges. Drawing on its deep technical expertise, FreeSpirit Instruments provides a critical “measurement benchmark” for the gallium oxide industry chain.
In substrate and epitaxy processes, FreeSpirit’s AFM product series, with sub-nanometer resolution, enables precise characterization of wafer surface morphology. By monitoring atomic-level roughness after chemical mechanical polishing (CMP), it effectively evaluates substrate quality. Meanwhile, AFM can probe microscopic defects on epitaxial surfaces, providing essential data support for process optimization.
At the device development stage, AFM not only performs critical dimensional measurements but also enables multifunctional property characterization, such as surface potential mapping (KPFM) and piezoresponse analysis (PFM), helping researchers and engineers gain deeper insights into the electrical distribution and physical properties of gallium oxide materials.
In addition, by integrating White Light Interferometry (WLI) for fast, non-contact, large-area surface measurement, FreeSpirit offers a full-scale metrology solution ranging from macroscopic flatness and step height to microscopic morphology.
FreeSpirit Instruments is committed to leveraging high-quality domestic precision metrology technologies to help industry partners accurately capture the “subtle details” of gallium oxide materials, thereby supporting the high-quality development of China’s advanced semiconductor industry.
