Our customer, STMicroelectronics, was struggling with an old and aging resist dispense pump installed base. Entegris proposed they evaluate the IntelliGen® LV two-stage technology dispense system. **Discover how STMicroelectronics has achieved with Entegris’ solution:** - Three times lower wafer defectivity - 30% tighter wafer dispense uniformity - Stability over six months of operation This case study looks at how to effectively collect data to improve your process control strategy and lower defectivity.   ### REGISTER FOR CASE STUDY - [![Facebook](https://info.entegris.com/hubfs/Entegris_Aug2019/Images/facebook.svg)](https://www.facebook.com/EntegrisInc) - [![Twitter](https://info.entegris.com/hubfs/Entegris_Aug2019/Images/x-logo.svg)](https://twitter.com/Entegris) - [![YouTube](https://info.entegris.com/hubfs/Entegris_Aug2019/Images/youtube.svg)](https://www.youtube.com/user/EntegrisInc) - [![LinkedIn](https://info.entegris.com/hubfs/Entegris_Aug2019/Images/linkedin.svg)](https://www.linkedin.com/company/entegris) - [![Instagram](https://info.entegris.com/hubfs/Entegris_Aug2019/Images/instagram.svg)](https://www.instagram.com/entegrisinc/) - [Privacy Policy](https://www.entegris.com/content/entegris-live/en/home/about-us/legal-trademark-notices/privacy-policy.html) - [Terms & Conditions](https://www.entegris.com/content/entegris-live/en/home/about-us/legal-trademark-notices/terms-and-conditions-of-sale.html) - [Legal & Trademark Notices](https://www.entegris.com/content/entegris-live/en/home/about-us/legal-trademark-notices.html) © 1994-2026 Entegris, Inc.
