Accelerating New Memory Materials Research

Intermolecular Characterization ChartWith all the new emerging memories that are being developed there must be quite a number of test runs to study exactly how well these new technologies and materials can perform.  If a batch of 300mm wafers must be used for a single test then the cost multiplies, particularly if no other test can be run on that wafer.

Another great difficulty is that most memory manufacturers run their wafers on very high-efficiency and high-volume wafer fabs.  It is perilous and wasteful to interrupt a production process to inject a batch of test wafers.  Most fab managers would rather have a tooth pulled than to change their flow to accept an experimental lot.

What can be done to improve this situation?

Well the folks at Intermolecular, Inc. (IMI) explained to the Memory Guy that they have a solution: They have built a small fab that allows single wafers to be processed with varying parameters across a single wafer.  In this way one wafer can be used to run 36 or more different experiments all at the same time.  This is clearly more economical than having to run the experiment on 36 wafers or, even worse, 36 batches of wafers!  Intermolecular says that, while production fabs are optimized for manufacturing, their fab is optimized for materials understanding.

The firm calls itself an Continue reading
