The terms “chiplet” and “heterogeneous integration” fill news pages, conference papers, and marketing presentations, and for the most part engineers understand what they’re reading. But speakers sometimes stumble during a presentation trying to figure out whether a particular die qualifies as a chiplet, and heterogeneous integration comes in different guises for different people. Both terms lack well-accepted definitions that can help navigate the nuances that now bedevil the terms. Promex COO Dave Fromm recently shared Promex’s unique perspective on both terms with Semiconductor Engineering.
