LineWorks SPACE

Active centralized manufacturing quality control

Flagship LineWorks SPACE (Statistical Process Analysis & Control Environment) is a powerful infrastructure solution for advanced SPC that gives you complete control over production quality across all your manufacturing sites. Relied upon by a wide range of global manufacturers, it has become the de facto standard in the semiconductor industry for integrated statistical process control. It interacts with multiple data sources and processes many thousands of online and offline charts, simultaneously. And it ensures you can track all your data by managing it within a centralized database, according to the ISO 9001 standard.


  • Faster problem resolution through complete visibility of production quality at all sites
  • Trend detection and early warning systems
  • Faster comprehensive reporting through online analysis
  • Easier, faster decision-making enabled by accelerated reporting
  • Improved traceability that also supports compliance fulfillment (i.e. FDA 21 CFR 11)
  • SPACE supports the implementation of your strategies, i.e. six sigma concepts
  • Corrective Actions (CA) with Trouble Shooting Guides (TSG)
  • Easy implemementation and integration of new tools
  • Solid base for customer audits

Real-Time SPC (Online SPC)

Online evaluation of more than 250.000 parameters based on more than 60 rules including Western Electric Rules. Automated online visualization of control charts as well as support for violations with CA (Corrective Actions), TSG (trouble shooting guides) and alarms.


Administration and Analysis (Offline SPC)

  • Logical Data Source support with free  definable keys
  • Flexible control limit calculations with pre-run function
  • Powerful search capabilities
  • Multi parameter, matching and normalized charts
  • Bookmarks
  • Versioning and Audit trail
  • Multi language support
  • Data export to external tools (qs-STAT, MS-EXCEL)
  • SPACE Dashboard including Web Charts


SPC Reporting

  • Automated cyclic reports: daily/weekly/monthly/quarterly/...
  • Standardized report types
  • Web reports

LineWorks SPACE 7.2 is now available!

Now, you can leverage its completely new validation framework to implement best SPC practices throughout your organization. Educate users on the proper setup of SPC charts, specification limits, and calculated parameters and prevent human errors from impacting your production right at the time when they happen. With an additional offline audit tool, you can generate a report on all your existing setup checked against additional rules. This allows refining either the rule or correcting your setup before these rules are rolled out into the production system.

Release 7.2 Enables You To

  • Apply 13 new real-time SPC rules in your production
  • Ensure enough headroom for your run-to-run (R2R) control after a tool maintenance through Greenzone checks
  • Detect Maverick lots without having to maintain an additional set of limits
  • Detect process trends and shifts in real-time when units are measured in different sequence than processed
  • Reduce redundant notifications for processes where corrective actions cannot fix the root cause immediately
  • Access to your control charts from web pages and emails more quickly
  • View 100.000 of samples in a chart through dramatically improved performance

and more…

Examples of new features in version 7.2

User-Friendly Corporate Governance Validation Framework

The user-friendly corporate governance validation framework supports you in defining your SPC strategy. You establish best SPC practices and avoid human errors. Validation rules are added as plug-ins. The rules verify the proper setup of control charts, specifications, and calculations when users want to change, create, or delete master data. If deviations are detected, the user gets feedback through messages with escalating severity levels info. The notifications contain warnings and error messages. Doing so, you prevent non-compliant changes from being implemented. In addition, an offline audit tool is provided that checks the existing objects with new rules before they are rolled out in a production environment.

New SPACE Chart Link Protocol Handler


LineWorks SPACE 7.2 comes with a novel protocol handler as a new client. This offers an improved way to link to the live SPACE-Charts from websites and notifications, even faster. The new links identify and use already running SPACE Navigators. In fact, they can start a new SPACE Navigator if required. Compared to the earlier applet-based Web Charts, the new client continues to run even if you navigate away from the embedding web page. In addition, multiple browser tabs can share the new handler. This technology significantly improves the speed of the chart links and reduces the amount of resources required at the clients in production and at the workplaces.

13 additional SPC rules including Greenzone and Maverick

Greenzone and Maverick rules are just two of the 13 new SPC rules added in version 7.2.

The Greenzone rule checks the quality more closely after a maintenance operation by tightening the control limits compared to normal production. For example, the control limits for the first units can be reduced to two-thirds (adjustable) after a tool maintenance.

In contrast, the Maverick rule refers to outliers that have a distance more than N times the width of the control limits away from the centerline.

Transiently Suppress Notifications

You can use this new function to suppress the sending of notifications about violations of special SPC rules for a certain period of time: no emails are sent, the SPACE Monitor is not activated, and no new eCAPs are triggered. You can specify whether the prevention is to take place for a certain time or for a certain number of samples. When a particular rule is violated for the first time, notification still takes place. The subsequent notifications about the rule violation no longer take place. This function enables you to temporarily avoid escalations if immediate corrective actions are deliberately not possible in production.

Western Electric (WE) Rules for Out-of-Sequence Samples

Whenever lots are measured in a different order than they were processed, it can happen that a sample is inserted between other samples since the order of processing is decisive for the time axis of the control chart. Previously, no evaluators were executed for such inserted samples that are based on a sliding window of N samples. With SPACE 7.2, this is now optionally possible by rating all sliding windows of size N that contain the inserted sample.

Improved Display Performance for Control Charts


The performance and memory efficiency of control charts have been greatly improved in the current version. For example, to display a control chart with 100.000 samples of sample size 1, the client now only needs one tenth of the time and one tenth of the memory compared to the previous version.

SPACE Chart Plug-Ins

… offer advanced analyses features directly at the graphical interface to operators and engineers. With ad hoc applicable correlation capabilities you will get more out of your data.
