Abstract: A robotic activity system, which includes a board and an autonomous robotic device, is described herein. The board may display a line and one or more color patterns. The robotic device may traverse the line using one or more integrated sensors. For example, sensor data may include light intensity data for visible light reflected or emitted by the board. The sensor data may be analyzed to 1) ensure the robotic device follows the line and/or 2) detect color sequences associated with color patterns shown on the board. Upon detection of a color sequence, the robotic device may attempt to match the color sequence with a known color pattern definition. The color pattern definition may be associated with a function to be performed by the robotic device. Using multiple sets of color patterns and associated functions allows the robotic device to move in a variable and potentially unpredictable fashion.

Abstract: The robotic activity system described herein provides for efficient communications between the robotic device and the board without the establishment of a wired or radio-frequency connection. In particular, through the simulation of touch events by the robotic device on the touch display of the board using capacitive elements on the robotic device, information/data may be communicated from the robotic device to the board, including the location of the robotic device relative to the touch display, the orientation of the robotic device relative to the touch display, status information of the robotic device (e.g., battery level, motor voltages, or wheel speed), and/or other similar pieces of information. Since this information is communicated using the conductive elements, a dedicated data connection, including separate radios and/or interfaces, is not needed. This communicated information may be used for conducting an interactive game involving the robotic device and the board or another activity.

Abstract: Using phase shifting on a mask can advantageously improve printed feature resolution on a wafer, thereby allowing greater feature density on an integrated circuit. Phase shifting can create an intensity imbalance between 0 degree and 180 degree phase shifters on the mask. An improved method of designing an alternating PSM to minimize this intensity imbalance is provided. Sub-resolution features, called “blockers”, can be incorporated in the alternating PSM design. Specifically, blockers can be formed in the 0 degree phase shifters. In this configuration, the intensity associated with the 0 degree phase shifters approximates the intensity associated with the corresponding 180 degree phase shifters. Intensity balancing using blockers retains image contrast, thereby ensuring printed feature quality.

Abstract: A system and method for integrated circuit design are disclosed to enhance manufacturability of circuit layouts through generation of hierarchical design rules which capture localized layout requirements. In contrast to conventional techniques which apply global design rules, the disclosed IC design system and method partition the original design layout into a desired level of granularity based on specified layout and integrated circuit properties. At that localized level, the design rules are adjusted appropriately to capture the critical aspects from a manufacturability standpoint. These adjusted design rules are then used to perform localized layout manipulation and mask data conversion.

Abstract: An integrated circuit lithography technique called spectral engineering by Applicants, for bandwidth control of an electric discharge laser. In a preferred process, a computer model is used to model lithographic parameters to determine a desired laser spectrum needed to produce a desired lithographic result. A fast responding tuning mechanism is then used to adjust center wavelength of laser pulses in a burst of pulses to achieve an integrated spectrum for the burst of pulses approximating the desired laser spectrum. The laser beam bandwidth is controlled to produce an effective beam spectrum having at least two spectral peaks in order to produce improved pattern resolution in photo resist film. Line narrowing equipment is provided having at least one piezoelectric drive and a fast bandwidth detection control system having a time response of less than about 2.0 millisecond.
