What is a KLARF file?

KLARF files mostly belong to KLA-Tencor Klarf Reader. KLARF files store wafer defect inspection data used in semiconductor manufacturing.
They contain precise details such as defect coordinates and measurement parameters from wafer inspections. These files are created and used by KLA-Tencor inspection tools and may also be referred to as KLA Result Files when the data is processed for analysis.
Usage Details:

Wafer defect inspection data – records defects identified during semiconductor wafer analysis.

Result files – formatted for use with dedicated software like KlarfViewer or KlarfExecutable.

FilExt.com note: Since the data is stored in a proprietary binary structure, it should be opened with KLA-Tencor’s specialized software rather than a standard text editor. For more technical details or updates, visit the KLA-Tencor website.

How can I open a KLARF file?

You need a suitable software like KLA-Tencor Klarf Reader to open a KLARF file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your KLARF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a KLARF file directly in the browser:.

KLA-Tencor Klarf Reader
KLARF files (KLA-Tencor Log And Results File) are the industry standard file format for storing wafer defect inspection data. They are primarily used in semiconductor manufacturing for analyzing and reporting defects found during the inspection process. These files play a crucial role in yield management and process control, allowing engineers to identify and address issues affecting chip production. The data within KLARF files is typically structured, containing information about defect coordinates, classifications, sizes, and other relevant metrics. This structured data enables automated analysis and reporting, facilitating efficient defect review and root cause analysis. While KLA-Tencor is the originator of the format, various software tools can parse and process KLARF files, making them a versatile option for defect data exchange and analysis across different platforms. This file format is classified as Data file.
