Patent number: 11195719Abstract: Embodiments of the present disclosure describe techniques for reducing in-plane distortion from wafer to wafer bonding using a dummy wafer. One embodiment is an apparatus formed using a dummy wafer, the apparatus comprising: a device layer fusion bonded to a first side of a carrier wafer, wherein the dummy wafer comprises a first wafer and the carrier wafer comprises a second wafer that is different than the first wafer; wherein the device layer comprise a portion of a third wafer that is different than the second wafer; and wherein a second opposite side of the carrier wafer includes: a removal process artifact, wherein a distortion signature present in the portion of the second wafer is indicative of the use of the dummy wafer fusion bonded to the second side of the carrier wafer, or a remainder of the dummy wafer. Other embodiments may be disclosed and/or claimed.Type: GrantFiled: April 2, 2018Date of Patent: December 7, 2021Assignee: Intel CorporationInventors: Chytra Pawashe, Daniel Pantuso

Patent number: 11171057Abstract: Fin-based transistor structures, such as finFET and nanowire transistor structures, are disclosed. The fins have a morphology including a wave pattern and/or one or more ridges and/or nodules which effectively mitigate fin collapse, by limiting the inter-fin contact during a fin collapse condition. Thus, while the fins may temporarily collapse during wet processing, the morphology allows the collapsed fins to recover back to their uncollapsed state upon drying. The fin morphology may be, for example, an undulating pattern having peaks and troughs (e., sine, triangle, or ramp waves). In such cases, the undulating patterns of neighboring fins are out of phase, such that inter-fin contact during fin collapse is limited to peak/trough contact. In other embodiments, one or more ridges or nodules (short ridges), depending on the length of the fin, effectively limit the amount of inter-fin contact during fin collapse, such that only the ridges/nodules contact the neighboring fin.Type: GrantFiled: December 30, 2016Date of Patent: November 9, 2021Assignee: Intel CorporationInventors: Glenn A.

Patent number: 11056356Abstract: Techniques and mechanisms for bonding a first wafer to a second wafer in the presence of a fluid, the viscosity of which is greater than a viscosity of air at standard ambient temperature and pressure. In an embodiment, a first surface of the first wafer is brought into close proximity to a second surface of the second wafer. The fluid is provided between the first surface and the second surface when a first region of the first surface is made to contact a second region of the second surface to form a bond. The viscosity of the fluid mitigates a rate of propagation of the bond along a wafer surface, which in turn mitigates wafer deformation and/or stress between wafers. In another embodiment, the viscosity of the fluid is changed dynamically while the bond propagates between the first surface and the second surface.Type: GrantFiled: August 24, 2018Date of Patent: July 6, 2021Assignee: Intel CorporationInventors: Brennen K.

Patent number: 10720345Abstract: Techniques and mechanisms for forming a bond between two wafers. In an embodiment, a first wafer and a second wafer are positioned with respective wafer holders, and are deformed to form a first deformation of the first wafer and a second deformation of the second wafer. The first deformation and the second deformation are symmetrical with respect to a centerline which is between the first wafer and the second wafer. A portion of the first deformation is made to contact, and form a bond with, another portion of the second deformation. The bond is propagated along respective surfaces of the wafers to form a coupling therebetween. In another embodiment, one of the wafer holders comprises one of an array of elements to locally heat or cool a wafer, or an array of displacement stages to locally deform said wafer.Type: GrantFiled: September 7, 2018Date of Patent: July 21, 2020Assignee: Intel CorporationInventors: Mauro J.

Patent number: 10707186Abstract: Techniques and mechanisms for forming a bond between wafers using a compliant layer. In an embodiment, a layer or layers of one or more compliant materials is provided on a first surface of a first wafer, and the one or more compliant layers are subsequently bonded to a second surface of a second wafer. The bonded wafers are heated to an elevated temperature at which a compliant layer exhibits non-elastic deformations to facilitate relaxation of stresses caused by wafer distortions. In another embodiment, a material of the compliant layer exhibits viscoelastic behavior at room temperature, wherein stress is mitigated by allowing wafer distortion to relax at room temperature.Type: GrantFiled: September 7, 2018Date of Patent: July 7, 2020Assignee: Intel CorporationInventors: Mauro J.

Patent number: 9691716Abstract: Techniques and structure are disclosed for enhancing fracture resistance of back-end interconnects and other such interconnect structures by increasing via density. Increased via density can be provided, for example, within the filler/dummified portion(s) of adjacent circuit layers within a die.

In some such cases, the floating filler line of the upper circuit layer may be formed as a dual-damascene structure including such a via. In some embodiments, a via similarly may be provided between a floating filler line of the upper circuit layer and a sufficiently electrically isolated interconnect line of the lower circuit layer.
