Technologies and Materials for Micro and Nano-electronics

In the article technologies used in micro and nanoelectronics there are shortly described. Attention is devoted to lithography as a basic technology. Principles of electron and ion lithography are mentioned as well as progressive ion projection lithography. Some remarks to nanotubes as means of cold cathodes for vacuum electron tubes for nanoelectronics are presented.

Dynamic Thermal Simulation and Modelling of Micro- and Nano-Electronics

As semiconductor devices continuously get both smaller and faster, a profound analysis of the dynamic (time-dependent) thermal behaviour is becoming more and more important. In this article some basic concepts and numerical methods for thermal characterization in the frequency domain are explained. Two practical examples are given. First a simple model is presented for a small package mounted o...

Buenos Aires – Octubre 2007 Micro - and Nano - NDE for Micro - Electronics ( back end )

Advanced techniques for nondestructive evaluation (NDE), having volume resolutions better than 1 micrometer voxel (three dimensional pixel) size, are urgently needed for the safety and reliability of electronic systems, especially those used in extended life applications. This paper presents the current status and future vision of sub-nanometer NDE. Techniques like acousticand X-ray microscopy,...

Effect of nano- and micro-roughness on adhesion of bioinspired micropatterned surfaces.

In this work, the adhesion of biomimetic polydimethylsiloxane (PDMS) pillar arrays with mushroom-shaped tips was studied on nano- and micro-rough surfaces and compared to unpatterned controls. The adhesion strength on nano-rough surfaces invariably decreased with increasing roughness, but pillar arrays retained higher adhesion strengths than unpatterned controls in all cases. The results were a...
