Deep Dive into Traceability Popup Elements

To ensure a thorough validation of the traceability popup, it's crucial to understand each element and its significance. Let's break down the key components:

Tool List and Green Ticks

The list of tools displayed in the popup (KLA TNR, SUSS, EVG, ONTODFY, CAMTEK, DRAGONFLY, ATRDA) represents the various equipment and systems involved in the wafer processing workflow. Each tool listed corresponds to a specific stage or process in the wafer's journey. The green ticks next to the tool names are visual indicators of data availability. A green tick signifies that the data related to that tool has been successfully populated in the traceability table. Conversely, the absence of a green tick, or a different indicator (such as a red cross or an empty checkbox), would suggest that the data for that tool is missing or incomplete. This visual representation allows for a quick assessment of data completeness, making it easier to identify potential gaps or issues in the traceability information.

When validating this aspect, it's important to verify that the list of tools displayed is comprehensive and includes all the expected equipment relevant to the wafer's processing history. Additionally, the accuracy of the green ticks should be confirmed. This involves checking that the tools with green ticks indeed have corresponding data in the table, and that tools without ticks are genuinely missing data. Any discrepancies found during this validation process should be investigated further, as they may indicate problems with data collection, processing, or display.

Traceability Table Columns: A Closer Look

The traceability table is the heart of the traceability popup, providing a structured view of the wafer's processing history. Each column in the table serves a specific purpose, contributing to the overall traceability picture. Let's delve deeper into the significance of each column:
