Noise Killed My Chip

In the past, noise was considered an annoyance, especially for analog circuitry. But today chips are actually failing because insufficient analysis was performed. Noise types that used to be second-order effects are becoming primary factors that have to be considered. This is happening at the same time that noise margins are getting smaller, both in the amplitude and temporal dimensions. It ... » read more

Designing SoC Power Networks

Designing a power network for a complex SoC is becoming critical for the success of the product, but most chips are still using old techniques that are ill-suited to the latest fabrication technologies, resulting in an expensive, overdesigned product. Not only is the power network as designed too large, but this has several knock-on effects that impact area, timing and power. In the first pa... » read more

Electromigration: Not Just Copper Anymore

While integrated circuit manufacturers have worried about electromigration for a long time, until recently most of their concerns have focused on the on-chip interconnects. The larger dimensions found in integrated circuit packages have, in most cases, improved heat dissipation, reduced current density, and eliminated most [getkc id="160" kc_name="electromigration"] risks. Over the last sev... » read more

2.5D Becomes A Reality

Semiconductor Engineering sat down to discuss 2.5D and advanced packaging with Max Min, senior technical manager at [getentity id="22865" e_name="Samsung"]; Rob Aitken, an [getentity id="22186" comment="ARM"] fellow; John Shin, vice president at [getentity id="22903" e_name="Marvell"]; Bill Isaacson, director of ASIC marketing at [getentity id="22242" e_name="eSilicon"]; Frank Ferro, senior di... » read more

Is The 2.5D Supply Chain Ready?

A handful of big semiconductor companies began taking the wraps off 2.5D and fan-out packaging plans in the past couple of weeks, setting the stage for the first major shift away from Moore's Law in 50 years. Those moves coincide with reports of commercial [getkc id="82" kc_name="2.5D"] chips from chip assemblers and foundries that are now under development. There have been indications for... » read more

Mobile Packaging Market Heats Up

Apple, Samsung and others are developing the next wave of smartphones and tablets. OEMs want to cram more chip functions in smaller IC packages, but there are some challenges in the arena. In fact, there are signs that the mainstream packaging technology for mobiles is running out of steam. For some time, mobile products have incorporated a technology called package-on-package (PoP), which u... » read more
