  • Patent number: 10546743
    Abstract: Ultra-low-k dielectric materials used as inter-layer dielectrics in high-performance integrated circuits are prone to be structurally unstable. The Young's modulus of such materials is decreased, resulting in porosity, poor film strength, cracking, and voids. An alternative dual damascene interconnect process incorporates air gaps into a high modulus dielectric material to maintain structural stability while reducing capacitance between adjacent nanowires. Incorporation of an air gap having k=1.0 compensates for the use of a higher modulus film having a dielectric constant greater than the typical ultra-low-k (ULK) dielectric value of about 2.2. The higher modulus film containing the air gap is used as an insulator between adjacent metal lines, while a ULK film is retained to insulate vias. The dielectric layer between two adjacent metal lines thus forms a ULK/high-modulus dielectric bi-layer.

A molding compound is then formed in the plurality of recesses and apertures in the leadframe to form a pre-molded leadframe. A plurality of die and wires are coupled to the pre-molded leadframe and the resulting combination is covered in an encapsulant. Alternatively, a bare leadframe can be processed and the metal layer can be applied after encapsulation. A saw or other cutting means is used for singulation to form leadframe packages. Each resulting leadframe package has a solder wettable sidewall for improving the strength of solder joints between the package and a circuit board.

  • Patent number: 10535588
    Abstract: The present disclosure is directed to a die having a metallized sidewall and methods of manufacturing the same. A contiguous metal layer is applied to each edge of a backside of a wafer. The wafer is cut at a base of a plurality of channels formed in the backside to create individual die each having a flange that is part of a sidewall of the die and includes a portion that is covered by the metal layer. When an individual die is coupled to a die pad, a semiconductive glue bonds the metal layer on the sidewall and a backside of the die to the die pad, which decreases the risk of delamination along the sides of the die. The flange also prevents the glue from contacting the active side of the die by acting as a barrier against adhesive creep of the glue up the sidewall of the die.

  • Patent number: 10530920
    Abstract: A portable device includes one or more memories and travel mode control circuitry coupled to the one or more memories. The travel mode control circuitry, in operation, monitors motion data and temperature data to detect a first travel state of the device. When the first travel state of the device is detected, motion data and pressure data are monitored to detect a transition from the first travel state to a second travel state of the device. When the transition to the second travel state of the device is detected, one or more control signals are generated to cause the device to enter a first travel mode of operation.
