The IVS 380 is an optical overlay, CD & z-height metrology system designed for high volume manufacturing, with SMIF (200mm substrate) or FOUP (300mm substrate) load ports compatibility. It handles various substrates for advanced packaging, including Si, glass and CCL, and accommodates sizes of 200mm and 300mm.

Building on the IVS family’s 40 years of experience in CMOS, MEMS and compound semiconductor applications, the IVS 380 system possesses the versatility to tackle overlay, CD and z-height measurements for diverse substrates and layers. It measures critical dimensions in the xy plane and the vertical z-heights of features like RDL metal lines, posts and bumps. The optics enable focus on mostly transparent materials such as photoresists and rough surfaces such as electroplated copper.

As semiconductor device technologies become increasingly complex, requiring thinner and more uniform films, the need for a stable, all-in-one thin film metrology solution becomes a necessity. By controlling the quality and effective thickness of gate films, the Iris G2 system supports critical device scaling and performance improvements.

For ultra-thin multilayer films measuring 10Å to 50Å, the Iris G2 system features deep ultraviolet (DUV) spectroscopic ellipsometry (SE) for common films and coupled proprietary laser ellipsometry technologies for critical films, providing customers with the flexibility to optimize cost of ownership, better stability, and ease of operation in a versatile tool for specialty, mature and advanced logic and memory processes.

Additionally, a single platform simplifies fleet management and fab operations while reducing overall capital investment.

An integrated metrology standard, the IMPULSE+ system offers high sensitivity and accuracy to CMP process excursions and enables device makers to establish APC control with high-accuracy feedback.
