Uniform Pressure Gang Bonding Method
20210398938 · 2021-12-23 ·

A uniform pressure gang bonding device and fabrication method are presented using an expandable upper chamber with an elastic surface. Typically, the elastic surface is an elastomer material having a Young's modulus in a range of 40 to 1000 kilo-Pascal (kPA). After depositing a plurality of components overlying a substrate top surface, the substrate is positioned over the lower plate, with the top surface underlying and adjacent (in close proximity) to the elastic surface. The method creates a positive upper chamber medium pressure differential in the expandable upper chamber, causing the elastic surface to deform. For example, the positive upper chamber medium pressure differential may be in the range of 0.05 atmospheres (atm) and 10 atm. Typically, the elastic surface deforms between 0.5 millimeters (mm) and 20 mm, in response to the positive upper chamber medium pressure differential.
