Title:
SUBSTRATE SURFACE TREATMENT METHOD AND APPARATUS
Document Type and Number:
Japanese Patent JP2004089848
Kind Code:
A
Abstract:

To solve the problem of deterioration and a short circuit of wiring caused by ion migration due to further decrease of pitch between electrodes formed on an IC chip along with high integration of a circuit within the IC ship.

High-frequency waves of 100 W (power density of 0.32 W/cm2) are applied to a high frequency electrode 16 while vacuum degree in a reaction chamber 12 is maintained at 120 Pa to generate CF4 gas plasma. A module substrate 15 is treated with the generated CF4 gas plasma to form a fluorine-containing film efficiently. A surface of the module substrate 15 is coated with the a fluorine-containing film, thus corrosion of gold or copper wiring and the ion migration between substrate electrodes 9 of an FPC 2 are prevented.
