  • Patent number: 7952207
    Abstract: Disclosed are embodiments of a flip-chip assembly and method using lead-free solder. This assembly incorporates mushroom-plated metal layers that fill and overflow solder resist openings on an organic laminate substrate. The lower portion of metal layer provides structural support to its corresponding solder resist opening. The upper portion (i.e., cap) of each metal layer provides a landing spot for a solder joint between an integrated circuit device and the substrate and, thereby, allows for enhanced solder volume control. The additional structural support, in combination with the enhanced solder volume control, minimizes strain on the resulting solder joints. Additionally, the cap further allows the minimum diameter of the solder joint on the substrate-side of the assembly to be larger than the diameter of the solder resist opening. Thus, the invention decouples C4 reliability concerns from laminate design concerns and, thereby, allows for greater design flexibility.

  • Patent number: 7952210
    Abstract: There is provided a semiconductor package comprising: a multilayer thin film structure including a plurality of dielectric layers and at least one or more redistribution layers; a semiconductor chip positioned at one side of the multilayer thin film structure and electrically connected to the redistribution layer; and a solder bump formed at the other side of the multilayer thin film structure. The multilayer thin film structure functions as the substrate for the semiconductor package and realizes the light, thin, short and small BGA package without any additional substrate. A plurality of the packages can be simultaneously formed at wafer level or carrier level, to simplify the process and to be favorable for mass production.

  • Patent number: 7952211
    Abstract: One or more electronic components can be mounted on the back side of a semiconductor die. The components can be passive components, active components, or combinations thereof. The components can be soldered to signal routes on the back side of the die, the signal routes being attached to the die using a metallization layer or using one or more dielectric layer sections. Placing components on the back side of the die can allow for incorporation of the components without necessarily increasing the form factor of the die's package.

  • Patent number: 7952213
    Abstract: An overlay mark arrangement for reducing the asymmetric profile and an overlay shift during an integrated circuit manufacturing process is disclosed. In one embodiment, the overlay mark arrangement may comprise a first mark, a second mark and a stress releasing means. The first mark is used to indicate the position of a lower layer, the second mark is used to indicate the position of an upper layer; and the stress releasing means is used to release the film stress induced by the upper layer. Unlike the conventional overlay mark arrangements, which will have a severe overlay mark shift due to the film stress, the asymmetric overlay mark profile can be improved by using multiple trenches around the overlay marks according to certain embodiments of the invention disclosed herein.

  • Patent number: 7952214
    Abstract: A wind power generation system temporarily stops a power converter when a system disturbance occurs, and reactivates the power converter after detecting a solution of the problem of an influence (overcurrent of a stator, direct current component of a stator, overcurrent of a rotor, etc.) of a fault occurring in a doubly-fed generator during a system fault. During a system fault, a reactive current can be safely output from a doubly-fed generator to an electric power system without destroying equipment of the wind power generation system.

  • Patent number: 7952216
    Abstract: A wind turbine generator system can regulate the rotational velocity of the wind turbine within an operation range even when the wind velocity suddenly changes and can perform continuous operation of the wind turbine. The wind turbine generator system includes a generator connected to the shaft of the wind turbine and a converter connected to the generator. When the rotational velocity of the wind turbine is within a predetermined range, power outputted from the generator is controlled so as to follow the instruction concerning the generator output given from the wind turbine to the converter. When the rotational velocity of the wind turbine is out of the predetermined range, the power outputted from the generator is controlled without following the instruction concerning generator output given from the wind turbine to the converter.

  • Patent number: 7952217
    Abstract: The invention relates to a wind turbine comprising a rotor including one or more pitchable blades, registration means for registering an idling power producing situation of the wind turbine in relation to a utility grid, detection means for detecting edgewise oscillations in one or more of the blades, and control means for controlling the pitch angle of one or more of the blades. The control means is adapted for changing the pitch angle of one or more of the blades when the registration means registers that the wind turbine is operating in an idling power producing situation and the detection means detects edgewise oscillations in one or more of the blades, hereby damping or eliminating the edgewise oscillations. The invention further relates to a method for controlling a wind turbine and use hereof.

  • Patent number: 7952218
    Abstract: A system for generating electricity includes a pump operable to convert wave motion from a body of water into mechanical energy. The pump includes an input port through which an operating fluid can enter the pump and an output port through which the operating fluid can exit the pump. A first outlet line and a second outlet line are fluidly coupled to the output port of the pump. A first reservoir is fluidly connected to the first outlet line, and a second reservoir is fluidly connected to the second outlet line, both reservoirs being selectively capable of receiving operating fluid driven through the output port.
