The new manufacturing method deals with the packaging substrate, the material to which chip dies are bonded. Intel and others have long used plastic (also known as organic) substrates, but the material can shrink or warp during the chip-making process, leading to defects.
Intel notes the warping risk grows as more silicon is placed on the substrate. “As the demand for data-centric, AI-centric compute increases, we are seeing an increasing amount of silicon being packed onto the package substrate, which organic packages have come to some kind of limitation in terms of handling it,” Manepalli added.
The company found a solution in glass, a homogenous substance that can remain rigid under a higher chip load. “Compared to today’s organic substrates, glass offers distinctive properties such as ultra-low flatness and better thermal and mechanical stability, resulting in much higher interconnect density in a substrate,” Intel said in its announcement.
