  • Patent number: 7897323
    Abstract: A method of achieving frequency doubled lithographic patterning is described. An optical pattern (16) having a first period (p1) is used to expose conventional acid-catalysed photoresist (18) on substrate (20), leaving regions of high exposure (24), regions of low exposure (26) and intermediate regions (22). Processing proceeds leaving regions (24) which received high exposure very polar, i.e. hydrophilic, regions (26) of low exposure very apolar, i.e. hydrophobic, and the intermediate regions having intermediate polarity. A developer of intermediate polarity such as propylene glycol methyl ether acetate is then used to dissolve only the intermediate regions (22) leaving photoresist patterned to have a pitch (p2) half that of the optical period (p1). Alternatively, the photoresist is removed from the apolar and polar regions leaving only the intermediate regions (22) again with the same pitch (p2) half that of the optical period (p1).

  • Patent number: 7897324
    Abstract: The present invention provides a method of lithographic patterning in order to the strength of the patterned photoresist. The method comprises: applying to a surface to be patterned a photoresist (18) comprising a polymer resin, a photocatalyst generator which generates a catalyst on exposure to actinic radiation, and a quencher; and exposing the photoresist (18) to actinic radiation through a mask pattern (12). This is followed, in either order, by carrying out a post-exposure bake; and developing the photoresist (18) with a developer to remove a portion of the photoresist which has been exposed to the actinic radiation. The polymer resin is substantially insoluble in the developer prior to exposure to actinic radiation and rendered soluble in the developer by the action of the catalyst, and wherein the polymer resin is crosslinked by the action of the quencher during the bake.

  • Patent number: 7899955
    Abstract: The present invention relates to an asynchronous data buffer for transferring m data elements of a burst-transfer between two asynchronous systems. The asynchronous data buffer comprises a data memory for storing m data elements of a data burst and a valid bit memory for storing m input valid bits corresponding to the m data elements. Input control logic circuitry generates the m input valid bits and controls storage of the same and the m data elements. After storage of the m input valid bits an input control signal is provided for inverting the input valid bits of a following data burst. Therefore, after each burst-transfer of m data elements the input valid bit is inverted, automatically rendering all data elements of a previous burst-transfer invalid.

  • Patent number: 7898338
    Abstract: An integrated HF-amplifier has an input bond pad, cells displaced in a first direction, and an output bond pad. Each has a amplifier with input pad, active area, and output pad. The active area is arranged in-between the input and output pads, and the input pad, active area, and output pad are respectively displaced in a second direction substantially perpendicular to the first direction. A first network interconnects input pads of adjacent cells, and extends in the first direction. A second network interconnects output pads of adjacent cells, and extends in the first direction. The first and second networks obtain an output signal at the output bond pad having for all interconnected cells an equal phase shift and amplitude for a same input signal at the input bond pad. At particular bias and phase shift conditions this provides a Doherty amplifier with improved efficiency at power back off.

  • Patent number: 7898352
    Abstract: The present invention relates in general to transferring the envelope information of a polar modulated signal to a varying pulsewidth signal, while the phase modulation is direct transferred to the phase modulation of this PWM signal. Accordingly, the resultant signal is a PWM-PPM-signal. Such a signal can efficiently amplified by use of switching amplifying stages. By the present invention four pre-distorted baseband signals are applied basically to 4 linear RF mixers and a two adders, which are, the only needed external RF building blocks to build the modulator according to the invention. That is, the basic idea of the invention resides in the way of modulation of the four baseband signals and the way of combining of the RF modulated signals.

  • Patent number: 7899141
    Abstract: Receivers (1) for receiving radio frequency signals need automatic gain control alignment by hand during the production process, which makes the production process more expensive, more time-consuming and less reliable (insight). By (basic idea) providing receivers (1) with a first and a second gain controller (38, 54) for controlling the gains of a first (radio frequency) and a second (intermediate frequency) stage (3, 5) independently from each other, alignment by hand is no longer necessary, which results in a less expensive, less time-consuming and more reliable production process. The gain controllers (38, 54) have gain detectors (41, 59) for detecting output signals, and gain generators (40, 58) for generating gain control signals, and control inputs (42, 60) for receiving the same reference level signal (REF) for controlling the gains in relation to the same reference level.
