WebSep 16, 2010 · Abstract: Ultra-thin chip warpage is believed to have significant impact on electrical behavior of devices and circuits when the chips are glue attached to a flexible substrate. In this paper, we have investigated this packaging related issue by comparing ultra-thin silicon chips of similar thickness (~20 μm) obtained from two fundamentally … WebApr 24, 2024 · The chip warpage after the bonding process was also verified by experiment. Lu and Chen systematically analyzed the thermal-induced warpage during the ACA-based UTCOF bonding process by finite element simulation and experiment. Results indicated that the ultra-thin chip warpage was highly dependent on the bonding …

WebHigh bonding temperature would be easy to lead chip damage and chip warpage. For diminishing the thermal damage resulted from the high bonding temperature during chip stacking, we used the anisotropic conductive film as an intermediate layer to bond the chips. In this paper, a new type of ACF with Ni/Au-coated polymer arrayed particles was ...
