Adaptive Layout Partitioning for Dark Field Alternating Phase-Shift Mask Design

A new partitioning methodology is presented to accelerate 130nm and beyond large scale alternating phase shift mask(Alt PSM) design flow.This method deals with granularity self adaptively.Phase conflicts resolution approaches are described and strategies guaranteeing phase compatible during layout compaction are also discussed.An efficient CAD prototype for dark field Alt PSM based on these algorithms is implemented.The experimental results on several industry layouts show that the tool can successfully cope with the rapid growth of phase conflicts with good quality and satisfy lower resource consumption with different requirements of precision and speedup.

浅析肠癌肝肺转移病因病机

大肠癌的肝肺转移主要归因于脏腑功能失调,尤其是大肠与肝、肺二脏之间的关联。癌毒初始聚积于大肠,随着病情进展,沿经脉扩散至肝脏和肺部。若肝气郁结或肝血亏虚,则气血瘀滞,癌毒易于积聚并扩散至肝。肺主一身之气,大肠糟粕积聚,传导失职致使肺宣发肃降失常,易于侵袭入肺,在此过程中,或因痰湿阻滞气机,瘀血阻碍血行,或因肝气犯肺,气血运行不畅,进一步助长癌毒的扩散和转移。本文从肝通大肠的经络、五行及藏象内涵角度和肺合大肠的脏腑、经络、体用及气化关系角度,阐述大肠癌肝肺转移发生的具体病因病机,临床上对预防大肠癌患者发生肝肺转移、遏制疾病进展意义深远。
