IVS 220 Metrology System

Inspectrology’s IVS 220 is manufactured in our Sudbury, Massachusetts USA factory. The IVS 220 is the next generation of the IVS line of work horse of CD and overlay metrology systems. The IVS 220 is the latest generation of the IVS line of CD and overlay metrology systems which started with the IVS 100, IVS 120, IVS 130, IVS 135, IVS 155, IVS 165 and IVS 185 and the IVS 200.

IVS-220 – 75-200 mm White Light Optical CD and Overlay Metrology for Semiconductor, LED and MEMS.

The IVS 220 has been designed for ultimate precision, TIS and throughput. The cornerstone of the IVS 220’s unbeatable reliability and stability is its mean-time between failure (MTBF) of 2100 hours. The IVS 200 series leads the industry, ensuring optimal system availability and years of problem-free operation. The robust design of the wafer handling and navigation system requires no operator assistance during recipe execution. Recipes and data remain stable over time.

Versatile wafer handling accommodates many variations in wafer composition including silicon carbide, quartz, glass, GaAs, GaN, LiNO3, InP and slotted wafers of various sizes. Square substrates are also supported.

The IVS 220 delivers unparalleled measurement performance on all layers with CD and overlay measurements in the same recipe. Specific algorithms for MEMS applications allow for measurement of a wide array of MEMS structures. The proven capabilities of the IVS 200 series to perform with high precision and rock solid reliability set this system apart.

The IVS 220 is completely compatible with the IVS 200 and job plans from the IVS 1xx systems can also be upgraded to the IVS 200 platform.
