HBM爆火：SK海力士，再超三星

Core Viewpoint - SK Siltron's sales to SK Hynix surpassed those to Samsung Electronics for the first time in Q1 2023, attributed to SK Hynix's success in high bandwidth memory (HBM) and server DRAM, while Samsung faced challenges [1][2]. Group 1: Sales Performance - In Q1 2023, SK Siltron sold wafers worth 124.4 billion KRW to Samsung (Company A) and 128.8 billion KRW to SK Hynix (Company B), marking a 27% decline in sales to Samsung and a 32% increase to SK Hynix compared to the previous year [1]. - This shift is significant as it marks the first time since SK Hynix's acquisition by SK Group in 2017 that sales to SK Hynix exceeded those to Samsung [1]. Group 2: Market Dynamics - The decline in Samsung's sales is attributed to weakened product competitiveness and a reduction in foundry capacity due to poor customer orders, leading to a 50% decrease in capital investment compared to the previous year [2]. - Conversely, SK Hynix has been maximizing production capacity for its 10nm fifth-generation process and has seen strong sales for products like HBM3E, while also investing in new factories [2]. Group 3: SiC Business Challenges - SK Siltron's SiC wafer subsidiary reported Q1 sales of 6.147 billion KRW with an operating loss of 63.4 billion KRW, a significant decline from the previous year's sales of 21.3 billion KRW and an increase in losses from 26.3 billion KRW [3]. - The SiC business, seen as a next-generation power semiconductor opportunity, is facing challenges in technology competitiveness and market conditions, leading to speculation that it may become a liability for SK Group [3].
