Using FD-SOI to Design Competitive Chips

FD-SOI solves challenges without complicating design and manufacturing.

Designing a successful consumer-type IC requires a balanced combination of:

  • packing in more differentiating features,
  • reaching good performance with low power,
  • keeping final application costs competitive,
  • and respecting time-to-market.

Figure 1 illustrates how just a few key features intrinsic to FD-SOI translate into advantages that serve those needs. Read More

Fully Depleted (FD) SOI for the Next Generation

FD-SOI is making the move towards industrialization. In this issue of ASN, experts from IBM, ST, Hitachi, Leti and Soitec detail their approaches.

What is it ?

In planar FD-SOI  (as opposed to the verticality of FinFETs), CMOS transistors are built into an ultra-thin layer of silicon over a Buried Oxide (BOx) (which can optionally be extremely thin, too). This makes them Ultra-Thin Body Devices, with unique characteristics.

Why use it?

Planar FD-SOI addresses the major scaling challenges beyond the 28nm node:

  • Lowering supply voltage (VDD – hence power consumption per device) while boosting the dynamic performance;
  • Stopping – even better, reversing – the dramatic increase of variability in transistor characteristics;
  • Continuing to shrink transistor dimensions while limiting leakage and other unwanted short channel effects.

As a result, the unique properties of fully depleted devices – combined with the simplicity of a planar FD-SOI process and optimized wafer costs – put FD-SOI in the cost-of-ownership “sweet spot” for finished chips. Read More

Toshiba’s Cell Regza TV

It’s on SOI. Here’s Why.

Toshiba’s new Cell Regza TV is poised to redefine both high-definition (HD) TV and TV-Internet convergence. At the heart of this strategy is the SOI-based Cell processor.

It was almost a decade ago when Toshiba first teamed with IBM and Sony to create the Cell. The SOI-based solution enabled the right balance of maximal performance in a minimal power envelope. IBM puts it in servers, and Sony in the PlayStation3™. Now, Toshiba has put it at the heart of its new flagship Regza. Read More
