Numerical Simulation of the Temperature on the Metallization of an Integrated Circuit and its Impact on Interconnect Lifetime

Autor: J. L. R. Bohorquez, R. L. de Orio, R. O. Nunes

Publikováno v: Journal of Integrated Circuits and Systems. 15:1-5

This paper demonstrates a finite element model to investigate the temperature change of the interconnects of an integrated circuit due to the power dissipation of the transistors in the substrate. The temperature of the local interconnect is more sig

Effect of Lines and Vias Density on the BEOL Temperature Distribution

Autor: R. O. Nunes, Roberto Lacerda de Orio

Publikováno v: Journal of Integrated Circuits and Systems. 14:1-9

A method to calculate the temperature distribution on the BEOL structure and its impact on the EM in a design environment has been developed and implemented. The study for a 45 nm technology indicated a large temperature variation from the local to t

Publikováno v: Science of The Total Environment. 650:868-877

Volatile organic compounds (VOCs) concentrations depend on several sources and factors, such as temperature, ventilation, and humidity. Sources can be external atmospheric pollution or indoor release from furniture, coatings or occupants. In this con

Formaldehyde exposure and atmospheric biomonitoring with lichen Cladonia verticillaris in an anatomy laboratory

Autor: Maria Cristina Canela, Eugênia C. Pereira, Rafael de Oliveira Costa, Izabela Gonçalves da Silva, Camila R. O. Nunes

Publikováno v: Environmental science and pollution research international. 28(35)

Formaldehyde is one of the most toxic contaminants of indoor environments and very common in the anatomy laboratory. In this work, we investigated the level of formaldehyde exposure to staff and students who attended an anatomy lab and in nearby envi
