Abstract: Provided herein are methods and related apparatus for mask reconstruction in an etch process. The methods involve depositing a sacrificial layer on the mask layer. The sacrificial layer may be used to protect position on the mask layer. Following mask reshaping, the sacrificial layer may be removed using the same etch process that is used to etch the target material.

Abstract: A driving control method for an intersection traffic light array is provided. The intersection traffic light array includes Nxi horizontal ground traffic light sets. The Nxi horizontal ground traffic light sets include a horizontal ground traffic light set pxi which is disposed at an intersection safety line position of an entrance lane xi of a planar intersection. The Nxi horizontal ground traffic light sets further include a horizontal ground traffic light set qxi which is disposed at a stop line position of the entrance lane xi. Each horizontal ground traffic light set includes at least one traffic light, and part or all of traffic lights of a horizontal ground traffic light set i are provided with a wireless driving signal input port and/or a wired driving signal input port.
