2024年6月12日 · Monitor Wafer是一种非生产晶圆（NPW），其主要目的是通过各种监控方法评估和确保机台的运行状态、工艺参数的稳定性以及产品加工过程的可靠性。 它们可以作为“探针”对设备 和 工艺进行实时或周期性的“体检”。

Monitor Wafer，即非生产晶圆（Non-Product Wafer，简称NPW），在现代半导体制造中扮演着至关重要的角色。 它并不直接用于最终产品的制造，而是作为一种过程监控工具，用于实时或周期性地“诊断”设备和工艺的健康…

The I-V curve appeared symmetric on both sides of the drain-current (DC) bias. The conductance symmetry on both sides of the DC bias indicates that the contact between the NPW and the Au...

2023年6月6日 · NPW是指非生产晶圆（Non-Production Wafer）。非生产晶圆是指不属于常规生产流程的晶圆。这些晶圆通常用于测试、实验或其他非生产目的。它们可能包括用于设备校准、工艺开发或研发活动的晶圆。非生产晶圆不用于商业销售或用于最终产品。

When a leakage occurs, the negative pressure wave (NPW) [67], which is generated by the leak, propagates toward both sides of the pipeline and is captured by PZT transducers. By analyzing the NPW signals, the leakage’s location can be revealed.

2025年1月24日 · Monitor Wafer是一种非生产晶圆（NPW），其主要目的是通过各种监控方法评估和确保机台的运行状态、工艺参数的稳定性以及产品加工过程的可靠性。 它们可以作为“探针”对设备和工艺进行实时或周期性的“体检”。

Results illustrate that the dominant mechanism of deformation for monocrystalline NPW is the combination of twin boundaries (TBs) migration and 1/2<111> dislocation mov...

2018年10月1日 · Rubber washers in assembled pipeline reduce NPW propagation velocity. The revised formula can calculate NPW velocity effectively. Practicality and accuracy of improved method are validated using a pipeline leak detection test platform.

Negative Pressure Wave (NPW) in pressure curve can be an indication of leakage of a pipeline. In this paper, we propose to use the support vector machine (SVM) learning to detect NPW in pressure curves. In the approach, NPWs detection is formulated as a supervised-learning problem and the method of SVM is employed to develop the detection ...
