Let’s Discuss Solutions Together Listen to this article ### Trend Grouping Solution for Semiconductor Backend Manufacturing ## Key Takeaways - Standard SPC charts can show process variation, but the initial view may not reveal whether a pattern is associated with a particular shift, time period, or equipment group. - The LineWorks SPACE Charts Trend Grouping Plug-in (TGP) allows semiconductor backend teams to segment and visualize existing production data using these different grouping perspectives. - Box plots and bar charts help engineers compare grouped results and identify differences or anomalies that require further investigation. - The integrated, no-code interface allows engineers to perform additional analysis within the LineWorks SPACE Chart environment. - Grouped trends help narrow root-cause analysis, but the observed relationship must still be investigated before a causal conclusion is made. [Semiconductor backend](/camline/industries/semiconductor-backend) teams need to understand not only whether process measurements vary, but also whether the observed patterns differ by production shift, time period, or equipment. A standard SPC view can identify changes in measurement behavior, but additional grouping may be needed to understand where those differences occur. **This Work Smarter video shows how the [LineWorks SPACE Charts Trend Grouping Plug-in (TGP) segments and visualizes semiconductor backend production data to support more focused analysis.](/camline/products/lineworks-space-chart-plugins)** ## Why Semiconductor Backend SPC Data May Need Additional Grouping Semiconductor backend manufacturing generates process and quality data across different equipment, production periods, and shifts. When measurements are displayed only in their original sequence, **engineers may identify an anomaly without immediately seeing the production conditions associated with it.** For example, similar measurements can produce different patterns when the data is separated by equipment or production shift. Without these comparative views, **engineers may need to sort or restructure the data manually before they can examine those relationships**. Grouping existing SPC data provides an additional analytical perspective. It helps process and equipment engineers determine whether an observed difference is distributed broadly or concentrated within a particular operational grouping. ## How the Trend Grouping Plug-in Groups Semiconductor Backend Data **The LineWorks SPACE Charts Trend Grouping Plug-in segments and visualizes existing production data by shift, time period, or equipment.** These grouped views allow engineers to compare relevant subsets of data within the LineWorks SPACE Chart environment. Instead of reviewing the entire dataset as one continuous series, **users can apply an appropriate grouping perspective to examine where patterns or anomalies occur.** ### Table 1: Trend Grouping Perspectives for Semiconductor Backend Analysis The appropriate grouping perspective depends on the process question being investigated. Engineers can use the resulting comparison to determine where more detailed analysis is needed. ### Visualizing Grouped Data with Box Plots and Bar Charts The Trend Grouping Plug-in **provides multiple visualization options, including box plots and bar charts**, for reviewing grouped production data. **Box plots** help engineers compare the distribution and variation of measurements across groups. **Bar charts** provide a direct visual comparison of grouped results. Using these views can make differences between shifts, time periods, or equipment easier to recognize than reviewing individual measurements alone. [The plug-in is integrated into the LineWorks SPACE Chart interface and supports no-code analysis.](/camline/products/lineworks-space-chart-plugins) Engineers can therefore explore additional views of existing data without moving the analysis into a separate tool or developing a custom visualization. ### Using Grouped Trends to Focus Root Cause Analysis Trend grouping helps engineers move from detecting an anomaly to identifying where the investigation should focus. For example: - **an equipment-based** difference may direct attention toward equipment-related conditions; - **a shift-based** difference may indicate that shift-related operating conditions require review; and - **a pattern associated with a particular time period** may help engineers determine when a change first appeared. These grouped relationships provide evidence that helps narrow the investigation. However, an observed relationship does not by itself establish the root cause. Engineers must still review the relevant process, equipment, material, and production context before reaching a conclusion. By reducing the amount of data that must be examined manually, grouped views support faster and more focused problem-solving. ## Extend Semiconductor Backend Data Analysis with LineWorks SPACE Charts Semiconductor backend teams need flexible ways to examine the production data already available in their SPC environment. **The Trend Grouping Plug-in extends LineWorks SPACE Charts with grouped views that help engineers compare results by shift, time period, or equipment.** These visual comparisons make it easier to identify patterns, recognize anomalies, and focus further investigation without relying on separate data-analysis tools.

A: An aggregate SPC chart can hide important variation because measurements from different shifts, time periods, or equipment are combined into one overall view. The combined process may appear stable even when one group behaves differently from the others. Separating the measurements into relevant groups allows engineers to identify patterns that warrant further investigation. ### Q: How does the LineWorks SPACE Trend Grouping Plug-in support root-cause investigation? A: The LineWorks SPACE Trend Grouping Plug-in supports root-cause investigation by helping engineers compare existing SPC data across dimensions such as shift, time period, and equipment. Box plots, bar charts, and access to the underlying data can reveal where a deviation is concentrated and help narrow the investigation. An identified relationship indicates an association, so engineers must still use process knowledge and supporting evidence to confirm the cause. ### Q: What data is needed to compare SPC trends across shifts, time periods, or equipment? A: Comparing SPC trends across shifts, time periods, or equipment requires measurements to be linked consistently to the production context being investigated. Useful comparisons depend on: - reliable timestamps; - consistent equipment identifiers; - clearly defined shifts; - consistent measurement units; and - other production attributes relevant to the investigation. Missing or inconsistent context can create misleading groups, so data preparation and governance should be checked before the results are used for operational decisions. ### Q: What should a semiconductor backend team validate when evaluating the Trend Grouping feature in the LineWorks SPACE Chart Plug-in? A: A semiconductor backend team should validate whether the Trend Grouping feature in the LineWorks SPACE Chart Plug-in helps engineers reproduce and investigate a known historical issue more efficiently. The evaluation should confirm that engineers can: - group existing SPC data by relevant context, such as shift, time period, or equipment; - compare the groups using the available visualizations; - access the underlying observations; - distinguish meaningful patterns from results affected by small sample sizes; and - reproduce the analysis using consistent grouping definitions. The team should also test usability with the intended users, performance at the expected data volume, and alignment with existing access controls and data governance. ## Let’s Discuss Solutions Together Tap into camLine’s decades of expertise in digital transformation to overcome your manufacturing challenges.
