Coupling & Crosstalk: 5 Thoughts About 5G

Coupling & Crosstalk is my column in the MEPTEC Report. This column appears in the Summer 2019 edition on pages 9-10.

Electronic coupling is the transfer of energy from one circuit or medium to another. Sometimes it is intentional and sometimes not (crosstalk). I hope that this column, by mixing technology and general observations, is thought provoking and “couples” with your thinking. Most of the time I will stick to technology but occasional crosstalk diversions may deliver a message closer to home.

IEEE Semiconductor Wafer Test Workshop 2012 – Opening Session & Keynote (Sunday)

Semiconductor Wafer Test Workshop SWTW banner

This year’s IEEE Semiconductor Wafer Test Workshop started on Sunday June 10th with a pleasant surprise. Due to a welcomed but unexpected wave of seventy walk-in registrations, there was insufficient seating at the opening dinner. Thankfully the hotel staff quickly adjusted to accommodate these additional guests. Attendance and interest in this year’s workshop was clearly up.

Jerry Broz, general conference chair, welcomed everyone with a brief overview and presented prizes for the first annual golf tournament. We then quickly proceeded with business as Matt Nowak (Senior Director, Advanced Technology, Qualcomm CDMA Technologies) provided the keynote “Emerging High Density 3D Through Silicon Stacking (TSS) – What’s Next?” Mr. Nowak discussed the increased amount of hype within the 3D semiconductor packaging market in the last year with everyone announcing something. And Thru Silicon Vias (TSVs) technology has already been in high volume production for image sensors for several years now but at a significantly lower density than for 3D packaging.

Why the great interest recently in 3D packaging using TSVs today? Three simple reasons:  Continue reading “IEEE Semiconductor Wafer Test Workshop 2012 – Opening Session & Keynote (Sunday)”

Change the Rules to Win!

Some consider the many of billions of dollars invested in the semiconductor supply chain to be huge bets on yet to be proven technology and future business. Even if you take a strict view of this as simply business it is possible to learn something from gambling.

The Atlantic tells the fascinating story of how Don Johnson took Atlantic City casinos for $15 M playing blackjack. Last year he won $5 M from Borgata in February, $4 M from Caesars in March, and $6 M from Tropicana in April. This wasn’t luck and he wasn’t card counting. How did he do this and how does this connect to semiconductors and Apple?
