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.

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:

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

40% 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 4 KB to 230 KB. The keywords FileTimestamp, InspectionStationID, SampleType WAFER;, ResultTimestamp, LotID, FileVersion 1 7;, SampleSize and TiffSpec 6.0 NA R; are typical for these files.
25% of all KLA files start with the magic bytes KLZIPv0, 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 40 KB to 84 KB. Several words can almost always be found in the files, e.g. KLZIPv0, EPIC and STEAM. A common filename is AppData.kla.

All other KLA files (35%) have no uniform format. If you want to find out which format your KLA file belongs to, just click on the button "Choose your .kla file to analyze".
