VLSI layout patterns provide critical resources in various design for manufacturability research, from early technology node development to back-end design and sign-off flows. However, a diverse la…
In wafer test, the probe mark center shall be close to the pad center as much as possible. But the traditional probe-to-pad alignment (PTPA) process cannot always meet the requirements. So a novel …
One of the most significant manufacturing issues is how to monitor and diagnose the state of machines from various sensor data. Detecting machine state changes is very important because it can prev…
This study practiced virtual metrology (VM) for the etch profile and depth in the deep silicon trench etching with SF 6 /O 2 /Ar plasma. Machine learning-based VM models constitute the classificati…
Contamination control and mitigation is a vital function in the semiconductor manufacturing process, especially with the ever-decreasing feature size of wafers making them more prone and sensitive …
Microchip features continue to reduce in size year after year. Oxygen (O 2 ) and moisture present in ambient air can cause product defects and therefore lower production yield. Smaller feature size…
The annual output value of Taiwan’s wafer foundry and IC packaging test ranks first worldwide. The electronics industry has a complete industrial ecological chain in the supply chain system of gl…
Wafer fabrication (Wafer Fab) involves state-of-the-art, expensive, and highly complex processes, and only little is known about its change qualification, a process that follows a strict guideline …
In the semiconductor manufacturing processes, a wafer bin map (WBM) represents electrical test results. In WBMs, defective dies often form specific local patterns; such patterns are usually caused …
We present a low-cost, vision-based method to study the effects of photo resist edge bead removal (EBR) width variability in a manufacturing environment. In micro- and nanofabrication manufacturing…
