The NewScientist article Silicon “Lego bricks” used to build 3D chips said
Silicon wafers covered with matching patterns of Lego-like teeth and holes could aid the development of 3D electronics, say UK researchers.
The vast majority of modern electronics are etched onto flat silicon wafers and increasing their speed normally involves squeezing more components onto the same surface area.
Now researchers are trying a different approach, by building electronics in three dimensions, typically by layering individual silicon wafers on top of one another.
Michael Kraft, Mark Spearing and Liudi Jiang at the University of Southampton, UK, have developed wafers fitted with matching sets of pegs and holes, resembling those found on Lego bricks. Tests suggest that this could provide a better construction method as microscopic features are more accurately lined up.
