Abstract: Some aspects of the present disclosure provide for a method of automatically balancing mask misalignment for multiple patterning layers to minimize the consequences of mask misalignment. In some embodiments, the method defines a routing grid for one or more double patterning layers within an IC layout. The routing grid has a plurality of vertical grid lines extending along a first direction and a plurality of horizontal grid lines extending along a second, orthogonal direction. Alternating lines of the routing grid in a given direction (e.g., the horizontal and vertical direction) are assigned different colors. Shapes on the double patterning layers are then routed along the routing grid in a manner that alternates between different colored grid lines. By routing in such a manner, variations in capacitive coupling caused by mask misalignment are reduced.

Abstract: This is a type of connection device between a toilet and a drainpipe, including a trap with an inlet connected to a toilet flush port and an outlet connected to the drainpipe. The trap has a bend part and a horizontal lower pipe connected to it. Upper and lower inner pipe walls of the horizontal lower pipe have different declination angles. There is a containing part in the inlet; and in the containing part there is a sealing part forming a sealing structure between the flush port and the inlet. This simplifies the complex structure of existing toilet drainage parts for on-site installation and for reliable use. The separated trap design includes structure that can generate a siphon phenomenon. At the time of sale, wash-down drainage can be easily transformed to siphon wash-down drainage just by changing parts, such as the trap of the toilet, thus improving the drainage effect.
