Researchers develop a new technique to bond GaN transistors to a silicon chip, with the ultimate goal of having more powerful and efficient wireless transmitters

As chip manufacturers edge ever closer to the limits of what can be achieved with silicon, researchers have been exploring ways of boosting performance and power efficiency by stacking other components. One such group from MIT has pushed the boundaries of what seemed impossible just a few years ago, though, by developing a technique to attach GaN transistors onto a silicon chip, which could lead to even better wireless devices.
