Wafer level packaging and the third dimension
Tuesday, September 23, 2008

Depending on how liberal one is in their definition of what a wafer level package is, the technology is either entering its second, third or perhaps even its fourth or fifth decade of use.

IC packaging technology retrospective
Monday, March 2, 2009All IC packaging technology structures since the invention of the integrated circuit itself have been tasked to perform, at a minimum, the simple and fundamental tasks of interconnecting and protecting the semiconductor die and making it useful for interconnection at the next level.

7.7 – IC packaging
Thursday, August 16, 2007While the glamour of the integrated circuit has diminished little over the nearly five decades of its existence, it has become increasingly clear in the last several years that the performance of semiconductor chips is being gated by the IC package.

PiP, PoP and PuP
Monday, April 6, 2009Since the beginning, all IC packages have been designed to perform the basic tasks of interconnecting and protecting the semiconductor die and making it useful for interconnection at the next level.

6.2 – Standards for IC packages: blessing or burden?
Wednesday, February 1, 2006Since shortly after the introduction of the first ICs there has been an effort to put in place standards for IC packages.
Is a standard lead pitch for components possible?
Tuesday, July 3, 2012IC packaging technology has led the march of progress since the earliest days of the electronics industry. Decisions made by those responsible for packaging integrated circuits have a ripple effect that extends to the rest of the electronics industry.

3d: Benefits and challenges
Thursday, September 26, 2013While a substantial amount of electronic interconnection has been performed in the 3rd dimension throughout the history of electronics, the pursuit of 3D interconnections at chip level is relatively new, even though some prescient inventors in the earliest days of the semiconductor industry foresaw its potential benefit.
