ARFTG

ARFTG is a technical organization interested in all aspects of RF and Microwave test and measurement.

 

This meeting was held in Madrid during EuMW 2018  on 27 September 2018. It was attended by approximately 20 people representing research institutes, universities and industry companies around the globe.

The meeting started with the conversation about the need for establishing recommendations for wafer-level measurements. Nick Ridler (NPL, UK), MTT Standards Liaison, discussed possibilities within the IEEE Standards process and suggested it might be time for the group to consider creating a working group with the aim of generating a Recommended Practice.

It was noted that such a group should also include on-wafer data users (e.g., designers and modeling engineers from industry) as well as those who are more measurement-centric.

Gai Ngoc Phung (FBH, Germany) presented a talk on what was learned about on-wafer calibrations from the European PlanarCal project, which recently concluded. Among items discussed were the impact of probe geometry, radiation and dispersion, and substrate modes.

Ryo Sakamaki (AIST, Japan) presented a talk on on-wafer measurements by beginner operators. Among the sub-topics discussed were probe planarization techniques and the challenges presented by TRL calibration to the novice operator (lateral probe motion).

Andrej Rumiantsev (MPI, Taiwan) started a discussion on the location(s) of on-wafer calibration reference planes. The challenges of which reference planes to use (and how to get to them with calibration/de-embedding techniques) in high-metal-layer-count processes were part of the discussion.


At the end of the meeting, the topic of lumped element calibrations and challenges including the calibration reference impedance was started and will be continued at future meetings.


The next meeting is tentatively scheduled to occur with the winter ARFTG meeting (during RWW week in January 2019).

The kick-off meeting of the On-Wafer Measurements Forum took place at the 88th ARFTG-conference in Austin, Texas. Building on the success and experience of the Non-Linear VNA Measurements Users’ Forum, the On-Wafer Measurements Forum is organized to provide an informal discussion platform for microwave measurements engineers from all corners of the user community.

The meeting was opened by the welcome note from Dylan Williams (NIST). Leonard Hayden (Qorvo) and Joe Gering (Qorvo) presented the concept of the Forum as well as observations of the activities in the area and contributors. James Booth (NIST) discussed areas of the wafer-level measurements and metrology activity at NIST.

The audience poll counted over twenty discussion topics proposed for the upcoming meeting and included: contact repeatability, propagation of the undesired modes, organic substrates, power calibration at the probe tips, impact of the probe tips on calibration and measurement results, and others.

The next On-Wafer Forum will take place during IMS week (culminating in the 89th ARFTG conference on Friday June 9th) on Thursday, June 8th, 15:00-16:30 at the Ala Moana Hotel.
