What is a KLA file?

KLA files mostly belong to KLA-Tencor.

KLA wafer inspection file: KLA files are used to store specific data from semiconductor inspection systems. They record wafer defect information produced by KLA-Tencor devices. For more details, visit KLA's website.

Other types:

KLAmath Geometry File / Keepsake Studio Layout File: These files hold layout and geometric data and may be used in design tools like Krita.

Ken Levine Archive (KLZIP): This type is a compressed archive used for game data. For support, check this site.

FilExt.com tip: Each KLA file requires the correct software based on its internal format. Identifying the file’s purpose is key to opening and viewing the data correctly.

How to open a KLA file

You need a suitable software like KLA-Tencor to open a KLA 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 KLA file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a KLA file directly in the browser:.

KLA-Tencor
See the previous paragraphs to learn more about the main application. KLA files are often referred to as KLA-Tencor data files because this type of file is primarily created or used by this software.
KLARFF
KLARFF is a form of semiconductor mapping often used to map defects in a wafer. The identifying characters used for this association are - Hex: 46 69 6C 65 56 65 72 73 69 6F 6E 20, ASCII: FileVersion.

KLA file format:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be deduced from the file extension and the signature. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Knowledge is power - this also applies when dealing with unknown or faulty files. Our examination of the KLA files comes to the following conclusion:

The KLA file extension is not widely used. Such a file includes different formats for the applicable programs. The following file formats are most commonly found in KLA files:

30% of all KLA files are KLARFF map-data files. The contents of these files are easily readable with a text editor. The file size is in the range of 5 KB to 330 KB. The file type is relatively new. The keywords FileTimestamp, InspectionStationID, SampleType WAFER;, ResultTimestamp, LotID, SampleSize, FileVersion 1 7;, TiffSpec 6.0 NA R; and FileVersion 1 2; are typical for these files. Such KLA files store data about klarf, xxxxxx, front, wafer and scan.
15% of all KLA files start with the magic bytes 00 60 00 00 00 00 00 00, which are always the first bytes of this file format. These are binary files, so they do not contain words or text. The file size is in the range of 10 KB to 10 KB. A common filename is ct.KLA.

All other KLA files (55%) have no uniform format, often, for example, KLZIPv and ZIXnmqj. These files sometimes refer to data, gardener, gangsta, panda or sample. If you want to find out which format your KLA file belongs to, just click on the button "Choose your .kla file to analyze".

How to solve problems with KLA files

Associate the KLA file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest KLA file format. Search, therefore, e.g. on the manufacturer website after an available KLA-Tencor update.
To make sure that your KLA file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
