The Research and Computer Aided Engineering group at Carrollton Technology Center of Halliburton is looking for an expert FEA analyst at principal engineer level. This position requires

1) Extensive experience with nonlinear finite element analysis and fundamental understanding and knowledge of Solid Mechanics.

2) In depth knowledge of finite element method, extensive experience with commercial FEA software, such as ABAQUS is highly desired.

A review article of our research at IBM TJ Wason Research Center in piezoelectronic transistor, an exploratory device beyond silicon, is published in MRS Bulletin, Volume 37, Issue 11, November 2012, pp 1071-1076. Your future computer may depend even more on the mechanics.

Packaging mechanical engineers conduct simulation of electronic packages
to optimize package design for compatibility with assembly processes
and for reliable operation in end user systems such as servers, game
consoles and network switches. Simulation is conducted using commercial
finite element software such as ANSYS or ABAQUS to predict package
component stresses and strains. Simulations are verified by measurements
of warpage and stresses / strains in the packages using Digital image
contrast, strain gages, capacitance meters, etc. Package material
properties such as coefficient of thermal expansion, Poisson ratio and
modulus that are required for simulation are measured using specialized
mechanical equipment. Thus, familiarity with numerical simulation

Low dielectric constant (low-k) is achieved often at the cost of degraded mechanical properties, making it difficult to integrate the dielectric in the back end of line (BEOL) and to package low-k chips. Development of low-k technology becomes costly and time-consuming. Therefore, more frequently than before, people resort to modeling to understand mechanical issues and avoid failures. In this paper we present three multilevel patterned film models to examine channel cracking in low-k BEOL. The effects of copper features, caps and multilevel interconnects are investigated and their implications to BEOL fabrication are discussed.
