Tired of digging through endless process reliability specification documents? If you are looking for an easier way to calculate the lifetime of your ICs, this webinar is just right for you.
We will introduce and demonstrate a new web application – the RelXplorer - which allows you to calculate lifetimes based on mission profiles. It covers all aspects from lifetime parameters and lifetime plots for MOS transistors, capacitors, dielectrics and interconnects.
During this webinar you will learn about the functions and usage of the RelXplorer tool including a live demo session. Join the webinar and find out how the RelXplorer can help you in achieving high reliability with your next IC design.

A tunable optical prism MOEMS based on the deformation of a liquid droplet is presented. An aluminum-nitride membrane is tilted by a novel type of thermo-mechanical actuator. The actuatio nprinciple is based on a thermo-mechanical modulation of the intrinsic stress in aluminum-nitride beams. Based on an analytical model, the key parameters of the actuator are optimized.

The downscaling in ULSI systems, extended life time requirements, the use under harsh environment conditions and new materials influence the reliability of components in terms of stress related defects, corrosion and radiation more and more.Harsh environment requires reliability goals which can be reached by a more application related reliability specification, by new processes, materials or design approaches. Thermal, electrical and mechanical behavior simulation can facilitate the necessary development work by the determination of the main failure mechanisms, the interaction of mechanisms, the degradation behavior of new materials and design.

Semiconductor passivation layer cracking is considered critical as it can lead to moisture ingress into the device circuits and cause corrosion. The issue is more acute for high aspect ratio thick top metallization where the stress intensity factor (SIF) is higher.

In this two-part series of papers, the goal is to reduce thermal stress impact on thick metal passivation. In Part II (this paper), the relationship between passivation thickness and the thermal stress was established using Response Surface Methodology Design of Experiments (RSM DOe).

Standard design passivation layers on thick (> 3000 nm) top metalization has a susceptibility for cracking due to thermal stress. In this two part series of papers, Finite Element Analysis (FEA) simulation with Comsol Multiphysics was used to understand the impact of thermal stress. In Part I (this paper), three different thermal stress conditions were investigated i.e. cool down after Chemical Vapor Deposition (CVD), the increase, and the decrease in temperature during temperature cycling.

Bond pad quality and reliability evaluation is part of important structure test for wafer fabrication. In order to ensure production consistency, and part of continuous monitoring, as well as new process qualification, bond pad evaluation through wire bond is required. Usually the test was conducted by proceed through standard IC packaging such as wafer saw, die attach and wire bond to simulate actual mass production environment. Optionally this can also be done by using wafer level wire bond. Main advantage of wafer level wire bond is shorter test cycle as compare to conventional package level bonding. This could be a significant time saving especially in the fast pace semiconductor field. Key concern of wafer level bonding is the correlation of bonding performance as compare to real application in the field.

Sensor interfacing is a crucial component for today’s systems in many application domains. Especially in automotive and manufacturing fields, high temperatures are encountered. For extracting the typically small sensor signals, an interface near the sensor is needed to provide a high-accuracy and robustness.
