Device coating

Model: Lucent T model

Modes used – AFM, WLI

In device packaging, protective coatings and electrode pads are commonly used. The Lucent T model was used in WLI mode to capture surface profile of the device. The AFM data from the edge of the electrode pad showed a different height value. The presence of double fringes suggests a more complex coating structure. This can be elucidated with our 3d analytics software to obtain and visualize all the layers. Our software can also detect the reflection spectrum, which can be used to overlay material related colour on the height data. For NDT on multilayered coatings, the Lucent T model could be your solution of choice.
