今天在工作时, 一周之内先后两片wafer 在process 完成后,机械手臂将其从反应腔室去除的过程中报警--pick up error, 其含义是没能按照预期将wafer 取出。 在分析这个问题时,仔细对比了主要参数,包括,clamp voltage,backside helium pressure/flow, dechuck 时所加反向电压已达到预设-800V, 但是由于没有helium flow...
在此以LAM E6机台作为案例介绍芯片制作过程中wafer transfer flow。 MES 派工后,内含25片wafer的FOUP(Front Opening Unified Pod,前端开启式晶圆传送盒 前开式晶圆传送盒_百度百科) 将会被自动化运送小车运送到对应机台的load port,机台识别完成后,将打开FOUP 门,ATM(EFEM:Equipment Front End Module,半导体设备...
Fig. 3: Process flowchart for pop-out metrology. A process flow chart that explains the step-by-step process and necessary inputs required at various steps for pop-out metrology. The dashed red box indicates the data acquisition process. Full size image Dual-layer pop-out metrology The demons...
A further increase in bit storage density was brought about by transitioning to the third dimension. Not by stacking 2D-NAND-like layers, because the number of process steps that would be required to do so would dramatically add to the cost. The basic idea behind ’true’3D NANDis to stack...
为了预测3D NAND闪存的剩余使用寿命以及提高数据存储的可靠性,本文设计了3D NAND闪存的高温和温度循环实验,分析了各项操作时间和原始错误比特数的变化趋势.同时建立了一种改进的Transformer模型,以预处理后的寿命特征数据为输入,对3D NAND闪存的剩余使用寿命进行预测.与LSTM,GRU相比,本文所建立模型在高温擦写实验数据集中...
