대표독립항:
1. An internal circulating fluidized bed polymerization reactor, comprising:
a draft tube installed in the polymerization reactor, in which at least one penetration hole penetrating an inside and an outside of the draft tube is formed;
a partition tube which is located between the draft tube and a side wall of the polymerization reactor and divides an inside area of the reactor into an annulus and an outside area;
a gas distribution plate which is formed with an inclination from an outside of the partition tube to the side wall of the polymerization reactor; and
an annulus distribution plate which is formed with an inclination from an outside of the draft tube to the partition tube.

발명의 명칭: Method for forming fine pattern in semiconductor device
대표도면:
대표독립항:
1. A method for forming fine patterns of semiconductor device, comprising the steps of:
forming first photoresist patterns on a semiconductor substrate on which a layer to be etched is formed;
coating the first photoresist patterns with a mirror interlayer;
forming a photoresist layer on a resultant structure; and
exposing the photoresist layer to a light having energy that is lower than a threshold energy (Eth) of the photoresist layer without an exposure mask, thereby allowing scattered reflections of the mirror-interlayer to form second photoresist patterns between the first photoresist patterns.
