Delving Into Defects Spurs Prospects For Chip Insulator

Summary:
A warm winter coat doesn't work nearly as well if it's full of holes. The same is true for hafnium oxide, a promising insulator for the next generation of smaller, faster microchips.

A warm winter coat doesn't work nearly as well if it's full of holes. The same is true for hafnium oxide, a promising insulator for the next generation of smaller, faster microchips.

While hafnium oxide prevents currents from leaking through the ultrathin layers of semiconductor chips more than 1,000 times better than conventional silicon oxide, its prospects have been dampened by too many current-draining defects.

Now a team of National Institute of Standards and Technology (NIST) and IBM researchers reports in the March edition of Electron Device Letters that they have quantified these "electrical capture defects" in a way that may help chipmakers reduce the defects or at least devise a way around them.

NIST researcher John S. Suehle called the team's measurements a "critical first step" for improving manufacturing processes.

Using a method called "charge pumping," the NIST and IBM scientists found where the defects occur near the interface between the silicon substrate and the hafnium oxide and how those locations are ultimately detrimental to transistor operation. The method involves applying a voltage pulse and then measuring the current coming from a transistor. By changing the characteristics of the voltage pulse used, the scientists were able to measure the electrical-capture capacity of the defects.
