摘要: A method of three-dimensionally integrating elements such as singulated die or wafers and an integrated structure having connected elements such as singulated dies or wafers. Either or both of the die and wafer may have semiconductor devices formed therein. A first element having a first contact structure is bonded to a second element having a second contact structure. First and second contact structures can be exposed at bonding and electrically interconnected as a result of the bonding. A via may be etched and filled after bonding to expose and form an electrical interconnect to interconnected first and second contact structures and provide electrical access to this interconnect from a surface. Alternatively, first and/or second contact structures are not exposed at bonding, and a via is etched and filled after bonding to electrically interconnect first and second contact structures and provide electrical access to interconnected first and second contact structure to a surface. Also, a device may be formed in a first substrate, the device being disposed in a device region of the first substrate and having a first contact structure. A via may be etched, or etched and filled, through the device region and into the first substrate before bonding and the first substrate thinned to expose the via, or filled via after bonding.

摘要: A method of bonding includes using a bonding layer having a fluorinated oxide. Fluorine may be introduced into the bonding layer by exposure to a fluorine-containing solution, vapor or gas or by implantation. The bonding layer may also be formed using a method where fluorine is introduced into the layer during its formation. The surface of the bonding layer is terminated with a desired species, preferably an NH2 species. This may be accomplished by exposing the bonding layer to an NH4OH solution. High bonding strength is obtained at room temperature. The method may also include bonding two bonding layers together and creating a fluorine distribution having a peak in the vicinity of the interface between the bonding layers. One of the bonding layers may include two oxide layers formed on each other. The fluorine concentration may also have a second peak at the interface between the two oxide layers.

摘要: A method of integrating a first substrate having a first surface with a first insulating material and a first contact structure with a second substrate having a second surface with a second insulating material and a second contact structure. The first insulating material is directly bonded to the second insulating material. A portion of the first substrate is removed to leave a remaining portion. A third substrate having a coefficient of thermal expansion (CTE) substantially the same as a CTE of the first substrate is bonded to the remaining portion. The bonded substrates are heated to facilitate electrical contact between the first and second contact structures. The third substrate is removed after heating to provided a bonded structure with reliable electrical contacts.

摘要: A method of connecting elements such as semiconductor devices and a device having connected elements such as semiconductor devices. A first element having a first contact structure is bonded to a second element having a second contact structure. A single mask is used to form a via in the first element to expose the first contact and the second contact. The first contact structure is used as a mask to expose the second contact structure. A contact member is formed in contact with the first and second contact structures. The first contact structure may have an aperture or gap through which the first and second contact structures are connected. A back surface of the first contact structure may be exposed by the etching.

摘要: A method for bonding at low or room temperature includes steps of surface cleaning and activation by cleaning or etching. One etching process The method may also include removing by-products of interface polymerization to prevent a reverse polymerization reaction to allow room temperature chemical bonding of materials such as silicon, silicon nitride and SiO2. The surfaces to be bonded are polished to a high degree of smoothness and planarity. VSE may use reactive ion etching or wet etching to slightly etch the surfaces being bonded. The surface roughness and planarity are not degraded and may be enhanced by the VSE process. The etched surfaces may be rinsed in solutions such as ammonium hydroxide or ammonium fluoride to promote the formation of desired bonding species on the surfaces.

The surface roughness and planarity are not degraded and may be enhanced by the VSE process. The etched surfaces may be rinsed in solutions such as ammonium hydroxide or ammonium fluoride to promote the formation of desired bonding species on the surfaces.
摘要翻译: 在低温或室温下接合的方法包括通过清洗或蚀刻进行表面清洁和活化的步骤。 一种蚀刻方法该方法还可以包括除去界面聚合的副产物,以防止反向聚合反应以允许诸如硅,氮化硅和SiO 2的材料的室温化学键合。 要结合的表面被抛光到高度的平滑度和平坦度。 VSE可以使用反应离子蚀刻或湿蚀刻来稍微蚀刻被结合的表面。 表面粗糙度和平面度不会降低,并且可以通过VSE工艺增强。 蚀刻的表面可以在诸如氢氧化铵或氟化铵的溶液中冲洗以促进在表面上形成所需的粘结物质。

摘要: A device integration method and integrated device. The method includes the steps of polishing surfaces of first and second workpieces each to a surface roughness of about 5–10 Å. The polished surfaces of the first and second workpieces are bonded together. A surface of a third workpiece is polished to the surface roughness. The surface of the third workpiece is bonded to the joined first and second workpieces. The first, second and third workpieces may each be a semiconductor device having a thin material formed on one surface, preferably in wafer form. The thin materials are polished to the desired surface roughness and then bonded together. The thin materials may each have a thickness of approximately 1–10 times the surface non-planarity of the material on which they are formed. Any number of devices may be bonded together, and the devices may be different types of devices or different technologies.
