Imide layer on wafer
Witryna4 gru 1997 · Abstract: A wafer edge seal ring structure is disclosed to provide reduced particulate contaminant generation during wafer processing of high density integrated circuits. The structure is formed by delimiting the deposition of layers at the peripheral edges of wafers. It is shown that as each layer is deposited and then essentially … Witryna18 sie 2024 · In the manufacturing process of IC, electronic circuits with components such as transistors are formed on the surface of a silicon crystal wafer. A thin film layer that will form the wiring, transistors and other components is deposited on the wafer (deposition). The thin film is coated with photoresist. 4.
