The AP family of lithography systems provides leading-edge technical performance and enhanced productivity for advanced packaging customers. Designed to optimize productivity for advanced wafer fabs, the AP family integrates the processing advantages associated with Ultratech's industry-leading advanced packaging lithography equipment with the productivity benefits of the company's new Unity PlatformTM. Ultratech's AP300/AP200 support a lower cost-of-ownership strategy due to significant throughput enhancements, higher reliability, and superior alignment and illumination systems. In addition, utilizing non-contact 1X projection imaging technology greatly reduces the risk of lithography-related yield losses, while also providing the unique capabilities required for processing leading-edge advanced packaging devices.

Key Features and Benefits:

  • Broadband illumination capability enables exposure of i-, gh- and ghi-line resists
  • Patented Machine Vision System (MVS) capability eliminates the need for dedicated alignment targets and simplifies process integration
  • Fully automatic wafer change supports 200 mm and 300 mm wafers
  • Improved wafer edge exposure and wafer edge exclusion capability provide customer productivity enhancements
  • Industry’s best equipment uptime along with self diagnostic capability and enhanced host communications
  • New platform enables a 20% productivity improvement, thereby supporting a lower cost-of-ownership strategy

AP GOLD & AP PLATINUM
The new 200mm Unity GOLD and 300mm Unity PLATINUM lithography systems were developed to deliver cost- effective solutions for advanced packaging foundry applications. These low-risk manufacturing solutions provide the cost-of-ownership (CoO), operational flexibility and technical performance essential for Ultratech's global customers. These products, built on Ultratech's highly successful and customizable Unity Platform™, represent a tangible solution to address market conditions witnessed by the leading wafer foundry customers. Unity GOLD provides 150- and 200mm wafer packaging solutions for flat panel display (FPD) driver chip applications, while the Unity PLATINUM lithography system provides 200- and 300mm wafer processing capabilities for high-volume advanced packaging chip manufacturing.

Key Features and Benefits:

  • Broadband illumination capability enables exposure of i-, gh- and ghi-line resists
  • Patented Machine Vision System (MVS) capability eliminates the need for dedicated alignment targets and simplifies process integration
  • Fully automatic wafer change supports 200 mm and 300 mm wafers
  • Improved wafer edge exposure and wafer edge exclusion capability provide customer productivity enhancements
  • Industry’s best equipment uptime along with self diagnostic capability and enhanced host communications
  • New platform enables a 20% productivity improvement, thereby supporting a lower cost-of-ownership strategy

Prisma-ghi
Ultratech's Prisma-ghi stepper is designed specifically to address a broad range of technology requirements for the nanotechnology, MEMS and advanced packaging research and development communities. The Prisma-ghi incorporates many of the same features as the Unity steppers, but does so with consideration for smaller, cost conscious research or limited volume manufacturing facilities.
The Prisma-ghi is based on the production proven Star 100 product platform and utilizes a 1X broadband optical system, which provides the ability to expose i-, gh- and ghi-line resist on the same tool. An optional illumination filter allows the selection of the desired exposure wavelength. In addition to superior imaging characteristics, this tool retains the small footprint and flexibility advantages associated with the Star 100 product platform. The broadband exposure capability, patented Machine Vision alignment System (MVS), dynamic focus capability and low initial system cost make this stepper an intelligent solution for any new or existing MEMS or wafer bumping R&D fab.

Key Features and Benefits:

  • Broadband illumination capability enables exposure of i-, gh- and ghi-line resists on the same lithography tool
  • Machine Vision System (MVS), a pattern recognition-based alignment system, eliminates the need for dedicated alignment targets and simplifies process integration
  • Large depth of focus capability enables superior image performance for both thick and thin resist film
  • 100, 125, or 150 mm wafer size handling capability with less than 30 minute wafer size change time
