After bonding at 200 C much of the wafer surface is well bonded (Fig. 2), but the circumference … WebApr 1, 2014 · Adhesion and mechanical reliability improvement is an important issue for flexible electronics due to weak bonds between silicon/underfill/polyimide interfaces. These interfaces are bonded with ... transparent portable devices and even to sensory skins and electronic textiles that are currently not possible with wafer-based ...
WebSingle or double side polished polyimide wafers and polished polyimide substrates in any size and thickness as low as 50 microns (2mils) are available on special order. Standard … WebA combination of material stack, CMP parameters and design rules enabled us to obtain defect-free bond interface across the wafer. Scanning acoustic microscopy, FIB-SEM and TEM cross-sections demonstrated a perfect SiO 2 /SiO 2 bonding as well as excellent Ti/Ti connections for Ti pads as small as 3×3 μm 2.
WebLow-temperature polyimide (PI) and non-conductive paste (NCP) were used to conduct two kinds of processes of hybrid bonding. If PI was coated and partially cured on a patterned wafer before CMP, co-planarization of nt-Cu/PI should be done afterwards to fabricate Cu/PI structure. The Cu/PI hybrid bonding can be achieved at 200 °C for 30 min. WebMay 31, 2024 · We have studied the hybrid bonding process with a copper (Cu)/polyimide (PI) system by optimizing aqueous acid treatment, height control of Cu protrusion, and …
