Microalignment using laser-softened glass bumps

Disclosed is a method for fabricating glass bump standoff structures of precise height, the method comprising providing oversized glass bumps on a glass substrate, providing a heat source to heat the bumps, positioning a substrate to be aligned on the oversized bumps, and reducing the height of the...

Zusammenfassung:Disclosed is a method for fabricating glass bump standoff structures of precise height, the method comprising providing oversized glass bumps on a glass substrate, providing a heat source to heat the bumps, positioning a substrate to be aligned on the oversized bumps, and reducing the height of the oversized bumps by a combination of manipulations comprising (1) softening the bumps by heating the bumps and (2) applying pressure to the substrate to be aligned.
