Chip testing & packaging
−11.06%반도체 후공정
Chip testing and packaging, known in Korea as 반도체 후공정 (back-end semiconductor process), covers the steps that come after silicon wafers are fabricated: cutting dies, packaging them into protective housings, and testing their electrical performance. Korean investors often group companies in this segment together because they share similar supply chains and are closely tied to demand for memory and advanced logic chips, and because they are frequently discussed alongside the broader semiconductor cycle.
