TSMC OIP: On the Road to the Silicon Super Chip

SAN JOSE, Calif.--If you're the world's largest foundry, there's no slowing down, especially if you're roaring down the road to the "silicon wafer-based silicon super chip."

That was my take-away earlier this week (Oct. 1) listening to TSMC Vice President of R&D and CTO Dr. Jack Sun during TSMC's Open Innovation Platform® (OIP) event here at Cadence headquarters.

TSMC CTO Jack Sun

From 20nm system-on-chip (SoC) production, to the ramp of 16nm FinFETs, to 7- and 5-nm technologies in the distant future, and R&D and capacity investments in between, the pace of innovation at the Taiwanese company seems faster than ever.

Mobile in the driver's seat

Part of it involves the requirements to keep up with power, performance, and area expectations that are higher and more intense in a system-design era driven by mobile devices.

The other is that the industry's rapid congealing around design ecosystems puts pressure on everyone--foundries, IP providers, EDA vendors, design-services companies, and the design chain in general--not to let others down.

No pressure there!

In an ironic twist of phrase, Sun (pictured here at an earlier event) told his audience of 1,000+ engineers: "We need each other to be competitive and we need each other to win."

Now and going forward

Here's where TSMC stands today, racing down the road to the future:

  • 20nm SoC: The 20nm ICs have been qualified for ramp, according to Sun. Customer product chips have been delivered successfully-the same product chip with good yield from both GIGAFABsTM in Hsinchu and Tainan, he added.

Sun told the audience:

"We continue to drive power, performance, and area scaling very aggressively. From the performance standpoint and power standpoint, on an annual basis we can give you more than 15% performance improvement at constant power. For the same speed--compounded annually--we can reduce your power by 20 percent."

  • 16nm FinFET: TSMC already has achieved better than its target yield on this type of device, Sun said, adding that performance of ring oscillators is "nearly on target." The company already has completed an ARM® A57 test chip, with fMax on spec, according to Sun.

"The reference flow, EDA, and IP ecosystem are ready," Sun said.

Beyond that--beyond the work underway on 7nm and 5nm technologies (process R&D alone is $1.5 billion a year)--there's the journey to the "super chip," as Sun put it.

Going up

The journey's underway: TSMC already has demonstrated vertical 3D capabilities in the form of its chip-on-wafer-on-substrate technology (CoWoSTM), which was introduced and tested out a year ago. The technology uses silicon interposer technology to connect multiple homo- or heterogenous ICs.

TSMC has demonstrated a CoWoS package with SoC, embedded stacked DRAMs, and third-party Wide I/O DRAM integrated together.

A technology called advanced integrated fan-out wafer-level package (InFO WLP) is a lower-cost and less-dense "cousin" of the silicon interposer, which has qualified WLP for production.

"These are real. We can integrate billions of transistors with a few hundred thousand microbumps," Sun said. Thickness in packaged form can be as little as 250 microns, he added.

"That's ideal for future mobile computing devices," he said.
