Wafer Inspection System
Feb 2009

FLANDERS, N.J., Feb. 13, 2009 – Rudolph Technologies Inc. has announced that its NSX series wafer inspection system now includes WaferWoRx probing process analysis, which identifies the cause of probe test failure mechanisms, providing faster problem resolution and improved yield.Rudolph_NSX.jpg

The NSX System detects probe marks and generates location and size information and other parameters. WaferWoRx converts what has been a manual and time-consuming process of gathering scrub data from various tools, correlating the data, and sifting through for trends, to automated data collection and analysis completed in a single step. It breaks the overall probing error into its core components (prober, probe card, setup), enabling rapid problem resolution. It also can prequalify test cells without risk to production wafers and evaluate the readiness of the probing process for advanced technologies such as multi-DUT and high pin count probe cards. Probe card performance can be tracked to predict the need for maintenance, thereby extending card life and maximizing card availability.

The NSX Series provides fast, repeatable, advanced macro inspection to detect defects created during wafer manufacturing, probing, bumping and dicing or through general handling. Macro defects (0.5 µm and larger) can have a major impact on the quality of a microelectronic device and on the yield of the manufacturing process. The NSX uses high speed optical microscopy to identify defective probe marks. This same optical characterization data from a well-designed sample of probe marks serves as the input to the WaferWoRx analysis module for processing and further identification of the error components.

The WaferWoRx probe process analysis capability is available now on the NSX Series and can be ordered as an upgrade for the NSX 100, NSX 105 or NSX 115 models.
