1. **技术方法**:采用改良半加成工艺(mSAP),将薄膜电阻(如NiCr)直接嵌入有机基板多层,替代传统分立电阻,减少表面积占用。 2. **核心优势**: - **微型化**:电阻尺寸可小至01005封装级别(如254μm×127μm),目标阻值100Ω。 - **信号完整性**:消除传统过孔结构,降低寄生电容,提升高频性能。 - **制造兼容性**:mSAP工艺实现25-30μm线宽/间距,兼容现有产线,无需专用设备。 3. **实验验证**:6层基板测试中,NiCr电阻层厚0.02μm,垂直于蚀刻方向时电阻公差约20-25%(目标±15%),可通过优化工艺改进。 4. **未来方向**:材料表征、长期可靠性测试(如热循环)及高频(40+GHz)电气测试。
