A Smarter, Quicker, Low-Cost Solution For Semiconductor Yield Management

If you work directly with STDF files, you need QuickLoad-Central. This powerful piece of software combines a host of essential functionalities into one convenient location, giving you full access to your STDF files.

Some of the highlights include:

1. Easily filter list of applicable files though key information such as lotid, waferid, date, file name, file location, product name, test program name, yield, and more.
2. Directly access and edit everything in your STDFs via our powerful STDF editor
3. Visualize data with histograms, paretos, box plots, wafer maps and many other tools, all with configurations such as separating by variable
4. Push data directly into JMP, Excel or other analysis tools for one or multiple files
5. Correct identifier problems (wrong lotid, missing wafer record, etc) across multiple files
6. Convert STDF files into standard formats like TDTF, CSV, XLS and JSON.
7. Create STDF files from TDTF or properly formatted CSV and JSON files.
8. Analyze or export data from STDF files stored in Amazon S3 cloud storage

Convenient Dashboard

If you are using Windows Explorer or Finder to pick the files to load into your analysis tool, you should be using the QuickLoad-Central dashboard. It will not only show you the STDF files, but their lot, date, sublot or waferid, yield and other information you need to quickly assess them.

QuickLoad-Central can also filter your STDF files by any combination of key header records, including wildcards. You can even edit the values of key fields such as lotid and waferid in multiple files directly from the dashboard, while generating the correct audit trail.

Data Extraction

Once you tell QLC the places your important STDF files are stored, it builds a list of all known STDF files in those locations (including sub-folders and zipped or gzipped files). It can optionally pre-generate data extracts for fast one-click loading into JMP, Excel or any CSV-reading analysis tool.

It also provides ad hoc push to JMP and Excel for all types of data in STDF files. But you don’t have to send your data to another tool to visualize it…

Visual Analysis

QLC provides its own powerful set of visualizations, including:

• Box plots
• Histograms
• Normal probability plots
• Pareto charts (failing tests, bins, bin percentages)
• Scatter plots
• Yield and test trend charts
• Wafer maps (bin maps, pass-fail maps, stacked bin maps, parametric test result maps)

QLC also provides statistical summaries and convenient lot summary reports. Visualizations include optional outlier filtering and many useful configuration parameters such as multiple levels of grouping variables and five types of line fitting.

Powerful Editing

In addition to its powerful dashboard, extract generation and data visualization capabilities, QLC also integrates for no additional cost our QuickEdit STDF editing tool. Any anomalies QuickLoad-Central helps you find in your STDF files, like mistyped lotids or unexpected die counts, can be quickly understood and corrected with QuickEdit.

1. Edit header information (lotid, waferid, etc.) in STDF files
2. Translate STDF to standard formats like TDTF, XLSX and CSV
3. Visualize parametric data in STDF files
4. Delete unwanted records from STDF files
5. View raw data in STDF files
6. Identify and correct problems that cause files not to load in enterprise yield tools
7. One page summary of file contents, including bin counts and failing tests.
