Silicon Box Pte Ltd is an independent advanced semiconductor packaging and chiplet integration company headquartered in Tampines, Singapore, founded in 2021 by Byung Joon Han, Sehat Sutardja and Weili Dai. It operates a $2B panel-level packaging foundry and provides the back-end interconnection infrastructure that makes chiplet adoption practical — from early design collaboration through final manufacture and test — functioning as an OSAT with an added design-consulting practice. It has shipped over 500 million units at high yield, joined the imec Automotive Chiplet Program, and is building a second €3.2B facility in Novara, Piedmont, Italy. Silicon Box is a semiconductor manufacturer, not a software vendor: it publishes no developer program, no API documentation and no machine-readable API contract. See x-coverage below for the measured basis of that statement.
