On Hermeticity Detection of Wafer Level Packages for MEMS Devices

January 2005

Wafer level packaging has emerged as one of the promising solutions for hermetic packaging of MEMS devices. Detection of the level of hermeticity of the package is essential for reliability and design assessment of the devices. Traditionally, hermeticity has been tested using Helium based fine leak testing. However, there are limitations when this technique is used for the hermeticity detection ... [Show full abstract] of small volumes (< 10−3 cc) that are typical in wafer level packages. This paper reviews the helium fine leak test, its limitations and the influence of the different test parameters on leakage rate measurement are analyzed for wafer level packages with small cavity volumes. The results indicate a need for development of a new hermeticity measurement technique to achieve the measurement sensitivity required for wafer level packages.

An improved phase de-embedding technique for high speed connectors

January 2010

As high-speed data applications, such as USB 3.0, are coming down to the consumer electronic world, there is a need of accurate methods to characterize channel behavior. This paper investigates further S-parameter phase errors when de-embedding a device under test (DUT) from onboard structures. A fixture model containing a DUT is constructed enabling the determination of the de-embedding ... [Show full abstract] solutions. From these solutions, new equations for DUT S-parameter phase sensitivity are developed. The improved method enables accurate de-embedding of the phase of high-speed connectors used in consumer electronics hardware.

Sensitivity and Trade-off Analysis in Multiobjective Programming

January 1989

Hirotaka Nakayama

In multi-objective programming, the trade-off analysis is one of the most important tasks. There have been many devices in interactive programming methods so that the decision maker can make his trade-off easy. The purpose of this paper is to present a method for making trade-off easy by use of sensitivity analysis in linear programming. Some special consideration will be given on the sensitivity ... [Show full abstract] analysis at the degenerate optimal solution in LP which has been developed just recently.
