In high-tech fields such as semiconductors, MEMS, solar energy, and medical devices, precise measurement of microscopic morphology is a core aspect of research and development and production. As a representative of domestically produced high-end step profilometers, ZEPTOOLS Technology, with its independently developed JS series products and its advantages in high-precision and multi-scenario adaptability technology, has been widely used in thin film testing, wafer analysis, MEMS manufacturing, and new energy material characterization, becoming a key tool in promoting precision manufacturing and material innovation.

I. Semiconductors and Integrated Circuits: Full-Process Quality Control from Wafer to Thin Film

Semiconductor manufacturing has extremely high precision requirements for surface morphology, and ZEPTOOLS Technology's step profilometers play a core role in wafer and thin film testing. Its JS2000C fully automatic model integrates an EFEM wafer transfer system, enabling unmanned 2D/3D step height and roughness measurements. It is suitable for roughness analysis of wafer surface oxide layers and photoresist, as well as the evaluation of surface flatness and defects such as depressions after chemical mechanical polishing (CMP). In the thin film field, using diamond probes and LVDT sensor technology, it can precisely measure the thickness of thin films such as silicon dioxide and metal layers (typically tens of nanometers), ensuring compliance with chip electrical performance requirements.

II. MEMS and Micro-Nano Devices: A "Microscope" for Microstructure Morphology

The micro/nano-scale structures of MEMS devices (such as sensors and actuators) directly affect their mechanical performance and reliability. ZEPTOOLS Technology's step profilometers support 2D/3D surface morphology scanning and can precisely measure the corrugation and radius of curvature of the surface of MEMS devices. Combined with stress measurement functionality, it prevents device cracking or delamination caused by stress concentration, providing key data support for MEMS research and mass production.

III. Solar Energy and Photovoltaics: A "Ruler" for Thin Film Quality

The thickness uniformity and surface roughness of photovoltaic thin films (such as amorphous silicon and CIGS) directly affect the photoelectric conversion efficiency. ZEPTOOLS Technology's step profilometers, by detecting thin film thickness and surface morphology, can optimize the preparation process of photovoltaic thin films; simultaneously, surface morphology analysis of transparent conductive oxide (TCO) layers can effectively reduce light scattering loss and improve battery performance.

IV. Medical and Biomaterials: A "Safety Guardian" for Implants and Coatings

In the medical field, the surface microstructure of biomaterials such as artificial joints and implants must meet biocompatibility and durability requirements. ZEPTOOLS Technology's step profilometers can precisely measure their surface roughness and morphological characteristics, ensuring good integration between the material and human tissue; in addition, in the field of drug coatings, it can also control the coating thickness and optimize drug release performance, providing technical support for medical device research and development.

V. Displays and LEDs: A "Booster" for Luminous Efficiency

The core of LED and display technology is the uniformity of the light-emitting layer and the flatness of the conductive film. ZEPTOOLS Technology's step profilometers can measure the step height and surface roughness of the epitaxial layer to ensure a uniform light-emitting layer structure; simultaneously, analysis of the thickness and surface flatness of the ITO (indium tin oxide) conductive film can optimize touch sensitivity and display effects. In the emerging field of circularly polarized light-emitting diodes (CP-LEDs), the step profilometer measures the thickness of quasi-two-dimensional perovskite thin films (such as 35-40 nanometers), providing key data for analyzing thin film growth uniformity and device performance, helping to solve the technical challenges of deep blue light emission.

VI. Electronic Devices and New Materials: A "Catalyst" for Low-Power Innovation

In response to the research and development needs of new electronic devices, ZEPTOOLS Technology's step profilometers have shown outstanding performance in the perovskite semiconductor field. For example, Fudan University's team used it to measure the thickness of Sn-based perovskite ferroelectric semiconductor thin films, combining doping technology to achieve the combination of strong ferroelectricity and semiconductor properties, developing ferroelectric field-effect transistors with the potential for non-volatile storage; in another study, by measuring the thickness of perovskite thin films after TEASCN regulation (35-40 nanometers), the optimization effect on crystal uniformity and mobility (>60 cm² V⁻¹ s⁻¹) was verified, providing support for the preparation of high-stability p-type perovskite transistors.

VII. Materials Science: A "Characterization Expert" in the Nano World

In the research of nanomaterials and two-dimensional materials (such as graphene), surface morphology characterization is the basis for understanding material properties. ZEPTOOLS Technology's step profilometers support 3D scanning functionality, generating color 3D surface morphology images. Combined with SPC statistical analysis, it provides quantitative data for material research and development, promoting breakthroughs in the performance of new materials.
