WebA wafer with 5μm thickness was used as an experiment. The wafer was dipped in the ALEGTM-368 product at 75°C followed by a water rinse step. To ensure uniformity of chemical performance, five locations were inspected by a scanning electron microscope (SEM) before and after treatment with the NMP-free product ( FIGURE 1 ). WebFOUP is a closed-type wafer carrier (container) for the transport and storage, conforming to the SEMI Standard E47.1. It has an opening and closing mechanism on the front. It is commonly used in the semiconductor factory of mini-environment system of …
