Contacting strips for electrodes of integrated circuit module - uses tongue shaped connector stamping with elasticised sections near proposed joints

摘要

A system for connecting the electrodes of integrated circuit modules using tongue contact strips made to the pattern of the layout. A relatively thick metal stamping is etched near the ends of the proposed joints leaving thin elasticised easily deformable strips which are later bonded with the electrodes of the semiconductor elements. The contact stamping is prepared by using a first masking technique reducing the sections of the proposed joints to thin membranes. A second masking process is then applied to these sections to produce shapes complementary to the electrode surfaces. After preparation the surface to be bonded is coated with a gold layer.
