3D-Micromac AG, Germany, the industry leader in laser micromachining and roll-to-roll laser systems for the semiconductor, photovoltaic, medical device, and electronics markets, introduced microPREP L\u2014the latest addition to its microPREP family of laser-based sample preparation systems, which is designed to support sample sizes up to whole 12-inch (300-mm) wafers and system-level boards.<\/p>\n

This new platform enables fast, precise, reproducible, and non-destructive material removal at scale, delivering significant productivity gains for failure analysis, process development, and quality assurance in the semiconductor and electronics industries. Multiple samples can be prepared at different locations on the wafers or system-level boards within a single workflow, without process restarts.<\/p>\n

Sample preparation remains one of the most time-consuming and costly steps in semiconductor failure analysis. Traditional preparation methods like mechanical polishing and focused ion beam (FIB) milling cannot meet the stringent needs of today\u2019s advanced applications. Mechanical polishing introduces mechanical stress to the specimen, which can affect the overall quality and yield. FIB milling is constrained by limited ablation rates, very small sample sizes, high tool operating costs, and the need for highly trained operators, making it impractical for large-scale or production-adjacent use.<\/p>\n

Integrated sample prep systems that combine laser and FIB tools in a single platform introduce capacity bottlenecks, as only one function can operate at a time. These systems also suffer from particle contamination, which can compromise the integrity of the sample and downstream analysis.<\/p>\n

Unlike hybrid platforms, the new microPREP L system is a dedicated, standalone laser micromachining solution that delivers precision, speed, and sample size scalability without compromise. Leveraging selective laser ablation and newly integrated real-time process monitoring, the system enables micrometer-level targeting and non-destructive removal of material\u2014even from large and complex assemblies such as advanced semiconductor packages, printed circuit boards, and whole 12-inch wafers.<\/p>\n

By supporting system-level preparation without cutting up the sample into smaller pieces, this platform helps preserve device integrity, accelerating failure localization and analysis. These capabilities also enable failure analysis to be extended beyond the lab and into fab environments, where rapid root-cause analysis is critical to improving yield and uptime.<\/p>\n

In direct comparison with other sample preparation methods for failure analysis, the new microPREP L provides a multitude of advantages.<\/p>\n
