Patent number: 10008469Abstract: An apparatus relates generally to a microelectronic package. In such an apparatus, a microelectronic die has a first surface, a second surface opposite the first surface, and a sidewall surface between the first and second surfaces. A plurality of wire bond wires with proximal ends thereof are coupled to either the first surface or the second surface of the microelectronic die with distal ends of the plurality of wire bond wires extending away from either the first surface or the second surface, respectively, of the microelectronic die. A portion of the plurality of wire bond wires extends outside a perimeter of the microelectronic die into a fan-out (“FO”) region. A molding material covers the first surface, the sidewall surface, and portions of the plurality of the wire bond wires from the first surface of the microelectronic die to an outer surface of the molding material.Type: GrantFiled: November 21, 2016Date of Patent: June 26, 2018Assignee: Invensas CorporationInventors: Rajesh Katkar, Tu Tam Vu, Bongsub Lee, Kyong-Mo Bang, Xuan Li, Long Huynh, Gabriel Z.

Patent number: 9847238Abstract: Fan-out wafer-level packaging (WLP) using metal foil lamination is provided. An example wafer-level package incorporates a metal foil, such as copper (Cu), to relocate bonding pads in lieu of a conventional deposited or plated RDL. A polymer such as an epoxy layer adheres the metal foil to the package creating conductive contacts between the metal foil and metal pillars of a die. The metal foil may be patterned at different stages of a fabrication process. An example wafer-level package with metal foil provides relatively inexpensive electroplating-free traces that replace expensive RDL processes. Example techniques can reduce interfacial stress at fan-out areas to enhance package reliability, and enable smaller chips to be used. The metal foil provides improved fidelity of high frequency signals. The metal foil can be bonded to metallic pillar bumps before molding, resulting in less impact on the mold material.Type: GrantFiled: February 27, 2017Date of Patent: December 19, 2017Assignee: Invensas CorporationInventors: Xuan Li, Rajesh Katkar, Long Huynh, Laura Wills Mirkarimi, Bongsub Lee, Gabriel Z.

Patent number: 9543277Abstract: A fan-out microelectronic package is provided in which bond wires electrically couple bond pads on a microelectronic element, e.g., a semiconductor chip which may have additional traces thereon, with contacts at a fan-out area of a dielectric element adjacent an edge surface of the chip. The bond wires mechanically decouple the microelectronic element from the fan-out area, which can make the electrical interconnections less prone to reliability issues due to effects of differential thermal expansion, such as caused by temperature excursions during initial package fabrication, bonding operations or thermal cycling. In addition, mechanical decoupling provided by the bond wires may also remedy other mechanical issues such as shock and possible delamination of package elements.Type: GrantFiled: August 20, 2015Date of Patent: January 10, 2017Assignee: Invensas CorporationInventors: Bongsub Lee, Tu Tam Vu, Rajesh Katkar, Laura Wills Mirkarimi, Akash Agrawal, Kyong-Mo Bang, Gabriel Z.

Patent number: 7016444Abstract: Filtering loop and method for maintaining synchronization between a receiver and a transmitter reduces overhead and enables more robust operation. The method includes the step of receiving an error signal corresponding to a synchronization parameter. A first order filter is applied to the error signal such that a residual signal results. The method further provides for compensating the residual signal for drift such that the compensated residual signal estimates a rate of change in the residual signal. By compensating the residual signal for drift, difficulties associated with time lag and signal degradation are obviated.Type: GrantFiled: March 26, 2002Date of Patent: March 21, 2006Assignee: Hughes Network Systems, LLCInventors: Michael Parr, Sharath Ananth, Long Huynh, Drew Barnett, Fred Harris
