WebTemporary bonding and debonding (TBDB) is a key technology in the semiconductor field to enable 2.5D/3D integration of devices. However, the conventional polyimides, which serve … Webfabricated on a sacrificial layer, then transferred to the device wafer with the help of temporary wafer bonding techniques and conductive glue. For the up-contact devices, prototypes were fabricated. Both liquid polyimide precursor and Kapton® film were used to produce polyimide flexible substrates with transferrable interconnect.
WebThe single crystalline thin film of Ge was transferred on the polyimide by adhesive wafer bonding and smart-cut techniques. A simple tunneling metal-oxide-semiconductor structure is fabricated for the detector applications. Due to the transparency of the polyimide, the responsivity of the detector is sensitive to the environments.

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 temporary/permanent bonding conditions for practical use. The study found that the treatment with an aqueous solution of citric or ascorbic acid and 80 nm-protrusion … 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.
