Abstract
A bump layout on the active region of a driver IC for increasing overall bump count. The layout fits IC packages that have a narrow and long body profile. Bumps are positioned close to the long side and central regions of the active region so that low marking pressure on the shorter sides of the package during chip-glass bondage is avoided. Dummy bumps may also be positioned close to the shorter sides of the package so that pressure distribution is optimized during chip-glass bondage.
Claims6
A bump layout on a driver integrated circuit (IC), comprising:
- a narrow and long driver IC package having an active region, wherein the package has a first short side, a second short side, a first long side and a second long side;
- and
- a plurality of bumps over the active region close to the first long side and the second long side and over some other part of the active region so that the active region is divided into a plurality of circuit blocks.
