SK海力士已经确认与台积电在下一代高带宽存储器(HBM)的量产上合作。SK海力士决定将HBM4基础芯片的半导体前端工艺(FEOL)、硅通孔(TSV)形成、BEOL等交由台积电负责,而从晶圆测试到HBM组装、已知良好堆叠芯片(KGSD)测试等后续工艺则在自家的后端工艺工厂进行。这意味着传统的前道工艺将由台积电承担,之后的工艺则由SK海力士负责。

PA54=1:驱动单元内部强制电机使能,而不需要外部输入信号SON。参数设置完成以后,保存后下电。2)手动运行步骤1.驱动器上电,显示R-0,是电机运行速度监视窗口。检查PA1参数是否和使用的电机代码一致。以上2步都无误后,进入“SR-/SR-RED”菜单下后,按↑、↓键开始运行电机。PLC控制运行伺服在手动调试下运行正常,现在进入PLC的上位控制,该控制中PLC的从伺服引入的IO如下:Input:SRDY——X2Output:PULS-:Y0SIGN-:Y1CCW:Y2CW:Y3SON:Y4为了控制方便,这里先把CCWCW信号使能。

虽然部分半导体领域的需求正在恢复,但复苏的步伐并不一致。目前需求的设备包括人工智能(AI)芯片和高带宽(HBM)存储芯片,这导致这些领域的投资和产能都在增长。然而,AI芯片对IC出货量增长的影响仍然有限,因为它们主要依赖于少数关键供应商。
TechInsights市场分析主管麦托迪夫(Boris Metodiev)表示,今年上半年的半导体需求喜忧参半。生成式AI需求的激增推动了存储和逻辑芯片的回升,但模拟、离散和光电芯片的需求有所回调,原因是消费者市场的复苏缓慢以及汽车和工业市场需求的减弱。麦托迪夫认为,随着AI边缘计算预计将刺激消费者需求的增长,半导体产业有望在下半年实现复苏。汽车和工业市场也有望在今年晚些时候恢复增长,这得益于利率下降提振消费者购买力以及库存的减少。
