  • Patent number: 10593678
    Abstract: A method of forming a semiconductor device comprises forming a patterned masking material comprising parallel structures and parallel trenches extending at a first angle from about 30° to about 75° relative to a lateral direction. A mask is provided over the patterned masking material and comprises additional parallel structures and parallel apertures extending at a second, different angle from about 0° to about 90° relative to the lateral direction. The patterned masking material is further patterned using the mask to form a patterned masking structure comprising elongate structures separated by the parallel trenches and additional parallel trenches. Exposed portions of a hard mask material underlying the patterned masking structure are subjected to ARDE to form a patterned hard mask material. Exposed portions of a semiconductive material underlying the patterned hard mask material are removed to form semiconductive pillar structures. Semiconductor devices and electronic systems are also described.

  • Publication number: 20190331501
    Abstract: This disclosure relates to a method and a device for planning route, a server and a robot. To satisfy the demand for outbound communication of a robot during its traveling process, in the method, a preset threshold may be preset according to communication quality requirements of communication parties, and then a region where communication signal strength is stronger than the preset threshold is selected out. The selected region is regarded as a route planning basis for route planning, so that communication signal strength on the planned route is stronger than the preset threshold. Thus smooth communication of the robot with the outside in the traveling process based on the planned route is achieved.

  • Publication number: 20170077812
    Abstract: A circuit includes an inductor that receives a switched input voltage to provide an output for driving a load. A driver circuit drives the switched input voltage to the inductor in response to input pulses. A ramp circuit coupled to the inductor generates a ramp signal emulating current of the inductor. A control circuit generates the input pulses to control the driver circuit based on the ramp signal and the output for driving the load. A transient monitoring circuit monitors the output with respect to a predetermined threshold and adjusts the ramp circuit based on the output relative to the predetermined threshold to control the emulated current of the inductor to facilitate jitter and load transient performance.

  • Patent number: 9548651
    Abstract: A circuit for controlling a switched-mode DC-DC converter. An inductor is connected between a switching node and an output node, and an output capacitor is connected in series with the inductor. An RC circuit is connected in parallel with the inductor to compensate for ripple voltage. In a discontinuous current mode, a pulse is applied to the switching node and then removed. In this mode, an RC time constant for the RC circuit is increased during the falling edge of a difference signal such that the difference signal does not drop below zero.
