Kepler says that it also has increased the density of SRAM by using ferroelectrics. read and write data at lower voltages It is more efficient than traditional mechanisms for processing and storing data. It achieved this feat by creating a composite low-voltage material that worked with the ferroelectric method.
SasiManipatruni is a Kepler Cofounder and Chief Technology Officer. He says that the Kepler Team went through 35 different composites to find a type of material they believed would be easier to manufacture and more cost-effective.
“Once we found a way to solve the physics problem—as in the physical limitations for HBM—we came up with a material innovation that helps with the amount of memory you can have between chips,” He says.
Kepler claims that in its initial build-outs, it was able convert a factory into a “next-generation” In just eight months you can achieve fab, as opposed to the usual 24-month period.
“Out goal is to take the fabs and architectures already built, and push them to the limits of physics,” Olaosebikan says.
Kepler bets that the additional cost of retooling or using new materials will far exceed the 20 billion to 40 billion dollars it would take to construct new fabs and equip them with hundreds of millions in equipment.
The Waiting Game
Kepler Computing still has a long road ahead before it reaches full-scale production—assuming it gets there. The company’s technology has been tested on roughly 2,000 wafers. The company says that it plans to ship the first HBM chip samples this year. Next year production will increase in Singapore, while production in America is expected to begin in 2028.
Kaste says that he is confident about the future of GlobalFoundries. “fundamental breakthroughs have happened. What remains is getting good results on thousands of wafers and millions of devices.”
He highlights that iron can be a problem with material systems like Kepler’s, because it is part of its composite. “Iron is a tough contaminant to introduce into a production facility. So Kepler’s solution has to run on dedicated equipment, or be fully encapsulated so that it can’t escape,” He says.
“The art is in keeping that material really well isolated through our production flow,” Kaste says.
