Mirror Surfaces Measured
Combines Moiré technology with Koh Young’s proprietary new optics to inspect highly reflective die surfaces in 3D, where conventional projection returns unusable data.
Height and Tilt
Full 3D height and tilt measurement, so a die that sits flat but skewed is caught as readily as one that sits proud.
Everything the Meister D Does
Retains the Meister D’s True 3D measurement for dies, small components, cracks, chipping and foreign material.
Meister D+
Meister series has been qualified for mass production by major semiconductor foundries and Mini/Micro-LED companies for micro solder and high-density substrates, shiny components, and highly reflective components with full 3D inspection performance.
Overview
In relation to Koh Young Technology, the overview of semiconductor technology highlights the importance of precision, innovation, and quality control in the production of semiconductor devices. Koh Young’s contributions to this field are centered around its advanced inspection and measurement solutions, which are critical for ensuring the integrity and performance of semiconductor components throughout the fabrication process.
FEATURES
Koh Young Technology leverages its expertise in 3D measurement and inspection to address the unique challenges of semiconductor manufacturing. This includes the precise inspection of wafer surfaces, critical dimension measurement, defect detection, and the analysis of complex structures found in semiconductor devices. These capabilities are essential for identifying potential issues early in the manufacturing process, thereby reducing the risk of costly reworks or failures in the final product.
Semiconductor Metrology
Semiconductor packaging has become one of the most dynamic areas of electronics innovation. From system in package (SiP) and chiplet integration to fan out wafer level packaging (FOWLP) and 3D stacked architectures, new designs are demanding extreme precision in assembly and inspection. Deviations in coplanarity, surface contamination, voids in underfill, or tilted dies can jeopardize signal integrity and mechanical reliability. To succeed in this environment, manufacturers need semiconductor metrology and inspection systems that deliver high resolution, high speed, and comprehensive 3D measurement capabilities, capable of analyzing everything from solder bumps to reflective silicon dies.
