Towards 5μm interconnection pitch with Die-to-Wafer direct hybrid bonding

ECTC 2021 Publications aux Conférences

Die-to-wafer direct hybrid bonding process is foreseen as a key enabler of heterogeneous 3D integration. Hybrid bonding technologies were first developed on W2W assembly reaching 3D interconnection pitch of 1μm . Recently, CEA-Leti demonstrated the feasibility of DTW direct hybrid bonding at 10μm with a specific die bonder (NEO HB) developed by SET Corporation. In this paper, the last improvements of DTW hybrid bonding process flow and die bonder alignment capability are presented. Main results showed an alignment capability improved to <1μm which enables bonding of die with <5μm interconnection pitch. Finally, multi-interconnection pitch bondings on a wafer were achieved with Cu pitches varying from 5μm to 10μm.

Die to Wafer Direct Hybrid Bonding Demonstration with High Alignment Accuracy and Electrical Yields

2019 International 3D Systems Integration Conference (3DIC) Publications aux Conférences A. Jouve; L. Sanchez; C. Castan; N. Bresson; F. Fournel; N. Raynaud; P. Metzger Sendai, Japan

Die-To-Wafer (D2W) direct hybrid bonding is foreseen as a major breakthrough for the future of 3D components; however, its industrialization rises some additional challenges compared to Wafer-To-Wafer processing. This paper presents a 300mm wafer complete solution developed at LETI to improve bonding yield of D2W hybrid bonding using copper interconnections until the assessment of the electrical performances thanks to a dedicated 300mm electrical test vehicle and robust stacking system. Stackings with +/-1.5μm accuracy and excellent bonding interface have been obtained (80% bonding yield). After stacking and annealing, the die can be thinned down to 10μm without damage. Electrical yield measured on daisy-chains with more than 20.000 connections present more than 75% yield and shown very limited drift after preliminary environmental reliability tests. All these results confirmed the high industrial potential of D2W hybrid bonding technology.
