联电(UMC)今日夜盘大涨5.02%，引发了市场的广泛关注。
消息面上，此次股价走强主要受到两大利好因素推动。首先，公司此前公布的第一季度财报表现极为亮眼，净利润同比激增108%至161.7亿新台币，大幅超出市场预期，同时毛利率达29.2%，产能利用率提升至79%。此外，成熟制程涨价趋势明确，第一季度平均售价同比增长8%，第二季度预计还将上涨5%至7%，市场预期其毛利率有望回升至30%以上。
其次，联电近日宣布推出用于显示驱动IC的14nm eHV（嵌入式高压）FinFET技术平台。据公司宣称，该新技术平台可较其最先进的量产eHV制程（基于22nm）降低40%功耗、节省35%芯片面积，有望支持更小型、轻薄的驱动模块设计，进一步延长移动设备的电池续航，并支持高阶与折叠式OLED智能手机显示应用。强劲的财务表现叠加前沿的技术突破，共同推动了公司股价的强势表现。
