StepFAST® software is Onto Innovation’s advanced lithography software solution tailored for fan-out panel-level packaging, where die placement errors and material instability can significantly impact yield and productivity. StepFAST® software uses a feed-forward adaptive shot approach, integrating high-speed die placement measurements from the Firefly® system and applying real-time corrections to every shot of the JetStep® lithography tool. This external measurement strategy doubles throughput compared to traditional on-tool (self-metrology) methods. The software also incorporates predictive yield analysis, enabling dynamic adjustment of exposure field sizes to balance throughput and overlay accuracy. By automating reticle selection and optimizing field coverage, StepFAST® software ensures efficient panel exposure while minimizing registration errors—from ±50µm down to under ±3µm. With advanced analytics, StepFAST® software transforms lithography into a flexible, high-efficiency process, delivering substantial improvements in yield, throughput, and cost of ownership for panel-level packaging applications.

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.

The IVS 280 system has been designed for ultimate precision, tool induced shift (TIS) and throughput for 100mm to 200mm wafers, with a mean time between failure (MTBF) > 2,000 hours. The IVS 280 system provides the same capability in a system designed for overhead track handling with full capability per SEMI® standards.

Flexibility is key in compound semiconductor processes, accommodating various wafer sizes, thicknesses, and compositions, including versatile wafer handling for Si, SiC, quartz, glass, GaAs, GaN, and LiNO3 wafers.

Its robust wafer handling and navigation system requires no operator assistance during recipe execution. The IVS 280 system enables wafer size changes without hardware alterations. Recipes and data remain stable over time. The system also supports recipe transfers from older IVS platforms like the IVS 200 and IVS 220.

The demonstrated capabilities of the IVS system to perform with high precision and solid reliability set this system apart.

The Element S system is designed for the specialty market, specifically the smaller 100mm to 200mm wafer sizes used in the rapidly growing Si/SiC/GaN power device market. Building on the success of the Element Fourier transform infrared (FTIR) system, the Element S system can accurately measure thickness and free carrier concentrations in epitaxial layers up to five layers. This capability is essential for characterizing the thick epitaxial films required for next generation SiC power devices, which need thick epi layers for higher standoff voltage.

With its small spot size, the Element S system can conduct measurements up to the very edge of the wafer, maximizing die yield and enhancing productivity as power device customers transition to 200mm wafers. With improved sensitivity, an advanced multi-layer epi algorithm, and leading-edge multiple IR peak modeling, the Element S system provides critical and versatile capabilities for wafer and device makers in epi and film composition monitoring.

The Element G2 system is designed for wafer suppliers to perform high speed impurity mapping and epi thickness measurements. It combines transmission and reflection-based technology and when paired with advanced IR modeling capability, it offers a unique approach to dielectric composition and film thickness monitoring. With improved sensitivity and cutting-edge algorithms, the Element G2 system is a critical metrology tool widely used for monitoring dielectrics such as BPSG, FSG, H in SiN, and more. Machine learning helps eliminate the need for monitor wafers in dielectric measurement.

The system features a crisp 2mm circular IR spot, a high sensitivity interferometer and advanced pattern recognition. Equipped with a Class 1, five-axis dual-arm edge grip wafer handling system, the Element G2 system delivers high precision and high throughput, even at the edge of the wafer.
