  • Patent number: 9703208
    Abstract: MQW devices, IC chips and methods may be used in semiconductor lithography patterning systems. An MQW device includes an array of pixels that have transmission elements and associated support circuits. The support circuits have preliminary memory cells and final memory cells. The final memory cells store transmittance values that control transmittances of the associated transmission elements. This way, exposure of a target with a lithography system for purposes of patterning the target may be performed through the transmission elements according to the controlled transmittances, while subsequent transmittance values are being received by the preliminary memory cells from memory banks. The exposure of the target therefore needs to pause for less time, in order to wait for the MQW device to be refreshed with the subsequent transmittance values. Accordingly the whole semiconductor lithography patterning system may operate faster and thus have more throughput.

The system and method are based on a multidimensional detection scheme that is sensitive to forces experienced by a biased electrode in a solution. The multidimensional approach allows separation of fast processes, such as double layer charging, and charge relaxation, and slow processes, such as diffusion and faradaic reactions, as well as capturing the bias dependence of the response. The time-resolved and bias measurements can also allow probing both linear (small bias range) and non-linear (large bias range) electrochemical regimes and potentially the de-convolution of charge dynamics and diffusion processes from steric effects and electrochemical reactivity.

  • Patent number: 9201241
    Abstract: A built-in self-calibration system and method for a micro-mirror array device, for example, operating as a variable focal length lens is described. The calibration method comprises determining a capacitance value for each micro-mirror element in the array device at a number of predetermined reference angles to provide a capacitance-reference angle relationship. From the capacitance values, an interpolation step is carried to determine intermediate tilt angles for each micro-mirror element in the array. A voltage sweep is applied to the micro-mirror array and capacitance values, for each micro-mirror element in the array, are measured. For a capacitance value that matches one of the values in the capacitance-reference angle relationship, the corresponding voltage is linked to the associated tilt angle to provide a voltage-tilt angle characteristic which then stored in a memory for subsequent use.

  • Patent number: 9164277
    Abstract: The force on the electrodes of an electrostatic field is used so that lateral tensile or compressive forces result which can deform a deformable element or can strongly deflect a deflectable structure. For this, a micromechanical device includes, apart from an electrode and a deformable element, an insulating spacer layer via which the electrode is fixed to the deformable element, wherein the insulating spacer layer is structured into several spaced-apart segments along a lateral direction, so that by applying an electric voltage between the electrode and the deformable element lateral tensile or compressive forces bending the deformable element along the lateral direction result. Thereby, the problem that normally accompanies electrostatic drives, namely the problem of the pull-in effect, is overcome. The deflection of the deformable element can be much larger than the gaps of the two electrodes, i.e. the above-mentioned electrode and the deformable element. A usage as a sensor is also possible.

  • Patent number: 9159277
    Abstract: A display includes an array of light modulators each having a first actuator and a second actuator. A control matrix includes a circuit having a first state inverter having an output coupled to an input of a second state inverter. A data store capacitor is coupled to an input of the first inverter and configured to store a data voltage corresponding to a future pixel state of the pixel. A first update interconnect is coupled to the first state inverter and configured such that altering a voltage applied to the first update interconnect causes the first actuator to respond to the stored data voltage. A second update interconnect is coupled to the second state inverter and configured such that altering a voltage applied to the second update interconnect causes the second actuator to respond to a voltage state of the first inverter.

  • Patent number: 9075234
    Abstract: A plurality of movable units is arranged in a matrix. First and second electrodes are used in common in the movable units arranged in a column. A plurality of third electrodes, which commonly connects tabular members of the movable units arranged in a row, is formed for each row. The drive circuit selects, in order and one by one, the third electrodes. Subsequently, the drive circuit swings the tabular member by applying a bias voltage to the selected third electrode and applying an approach voltage or a separating voltage to a plurality of the first electrodes and second electrodes. During a predetermined period of maintaining a swinging posture, the voltage applied to the third electrodes is maintained as the bias voltage. The tabular member is returned to a non-swinging state by changing the voltage applied to the third electrodes to a reset voltage after the lapse of the predetermined period.
