Welcome to the World of Micro Electronics using Micron Interconnect

Author: Michael Creeden CID+ Technical Director Design Education

One of the main benefits of microelectronics is the ability to create circuits with devices that are
smaller, faster, and more energy efficient than traditional electronic devices. When technology
advancements require these metrics to be improved, they challenge one another. The more
gates used in an IC, increases the functionality and the power requirements, causing thermal
challenges and size increases. The industry responds by lowering the voltage requirement and
reducing the size of gates, cells, and interconnects, which now allows for an increase in all the
metrics...

Advanced Via Solutions (Part 1/3)

Author: Michael Creeden CID+ Technical Director Design Education

Advanced circuit requirements are presenting new challenges every year. These challenges are
driven by the ever-increasing need to be smaller, faster, accomplish more, be cheaper, and often
must be accomplished quicker. So, each year we try to meet these needs by working smarter,
faster, more efficiently, adding technology and innovation. One of the most challenging features
on our circuit boards are the vias by which we make Z interconnects...

Advanced Via Solutions (Part 2/3)

Author: Michael Creeden CID+ Technical Director Design Education

Z-axis Interconnects can be completed by a technology called, Transient Liquid Phase Sintering (TLPS) materials, which is the use of copper sintering paste, i.e., Ormet® Paste Z-Interconnects,
this can be a very helpful alternative solution to conventional microvias. Ormet® Paste is an alloy
compound of Copper (Cu), Tin (Sn), and Bismuth (Bi) used as the binding agent...

Advanced Via Solutions (Part 3/3)

Author: Michael Creeden CID+ Technical Director Design Education

Today’s circuit boards often contain many rationales to implement HDI routing strategies.
HDI/Microvia Routing – There are several reasons to consider using HDI technology when
routing a circuit board. The most common of which is to improve the routability of the devices on the board, this means how many traces per each layer...

Signal Integrity, Electro-Magnetic Interference & Compatibility

Author: Michael Creeden CID+ Technical Director Design Education

Signal Integrity is a process to determine that the signal was delivered properly through a transmission line. Thus, a net could have good signal integrity or bad signal integrity. We must also consider that each net could induce a bad signal integrity phenomena to any adjacent net. This concept can have further-reaching concerns when energy emissions radiate and affect...

Universal Intelligent Input Data

Author: Michael Creeden CID+ Technical Director Design Education

Most great ideas originate with unknown sources, then someone claims the innovation. However, I’ve read somewhere that there is nothing new under the sun. All that to say, I’ve been talking this idea around for several years and I’m sure the smartest person in the room actually created it and that’s not me. I just wanted to go on record as someone pushing the idea forward…

Copper Electroplating Fundamentals

Author: DuPont™

Copper pillars are now common in flip chip interconnection, usually with a lead-free SnAg solder cap on top.

The transition to copper pillars has been driven by the limitations related to size and pitch (space between features) of traditional controlled collapse chip connection (C4) bumping.

As pitch requirements continue to shrink, copper pillars can....
