Wafer-Level RF MEMS Device Characterization in a Cryogenic Environment

Due to their intrinsic multi-physics nature, MEMS components and devices require very strict, demanding working ambient conditions. This is typically ensured by specific and often very demanding and e… [View More]

Factors Impacting Wafer-Level Test Productivity

In general, analytical probers used in test labs or fabless facilities are not equipped with automatic Probe-to-Pad Alignment (PTPA) technologies. PTPA errors must be corrected manually, adding unnece… [View More]

Advanced Curve Tracers for Superior On-Wafer Characterization

Emerging energy standards and increasing power consumption demand additional performance capabilities. These trends are clearly seen in industries such as aircraft, spacecraft, electrical power, commu… [View More]

Challenges with Wafer Probing on Fine-Pitch Micro-Bumps for 2.5D- and 3D-SICs

Recent advances in semiconductor processing technology enable the manufacturing of integrated circuits with Through-Silicon Vias (TSVs). TSV is a conducting “nail” that provides an electri… [View More]

Choosing the Optimal Two-Port Calibration Method

The purpose of this Agilent workshop at European Microwave Week 2011 was to contrast and compare the characteristics of the leading on-wafer calibration methods. Also as a suitable background, it offe… [View More]

Electrical Performance Effects on Wafer Level Test

Our own Mike Fredd recently gave a presentation on the electrical performance effects on wafer level test entitled The Electromechanical Design of Spring Pin Based WLCSP Contact Engine and Its Effect … [View More]
