Bonding ultra-dense bump arrays using alignment bumps
Additional “auxiliary” bumps are used to stabilize alignment and reduce slippage of dense arrays of interconnect bumps on opposing die during a bonding process. One example of auxiliary bumps are interdigitated bumps. Interdigitated bumps are more self-aligning and laterally stable because bumps do not meet head-to-head. Rather, the head of a bump on one die falls into the space between bumps on the other die. Another example of auxiliary bumps are nail bumps. In nail bumps, one bump is harder (the nail) and “drives” into the opposing softer bump during bonding. This constrains the lateral movement of the two bumps relative to each other and reduces lateral slippage. In some embodiments, the auxiliary bumps and interconnect bumps are formed in the same process, and also bonded in the same process. |

An electronic device coupled to a display includes a graphics card and a processor. The graphics card reads the extended display identification data from the display. The processor determines, according to the extended display identification data, that the display is able to display a default resolution at a first refresh rate at most, and determines, according to the extended display identification data, whether the display device is able to display the default resolution at a second refresh rate that exceeds the first refresh rate. When it is determined that the display is able to display the default resolution at the second refresh rate, the processor adds the second refresh rate into the extended display identification data. |
