Patent number: 8697585Abstract: A crystallization method is disclosed. In one embodiment, the method includes providing a substrate having an amorphous silicon layer, wherein the substate has first and second sides opposing each other and irradiating a laser beam onto the substrate so as to have an inclined angle with respect to the first and second sides of the substrate. The method further includes relatively moving one of the laser beam and the substate with respect to the other i) in a first direction from the first side to the second side of the substate and ii) in a second direction which crosses the first direction.Type: GrantFiled: January 21, 2013Date of Patent: April 15, 2014Assignee: Samsung Display Co., Ltd.Inventor: In-Do Chung

Patent number: 8404408Abstract: A mask for sequential lateral solidification (SLS) which is capable of preventing an overlapping region and a diagonal stain based on a crystallization pattern of an active layer. The mask for SLS, which moves in a first direction and selectively transmits a laser beam emitted by a laser emitting device, includes slits which are formed such that the width of a slit in the first direction is smaller than the width of the slit in a second direction, which is perpendicular to the first direction. Each of the slits is tilted by a predetermined angle with respect to the first direction.Type: GrantFiled: January 3, 2011Date of Patent: March 26, 2013Assignee: Samsung Display Co., Ltd.Inventors: Kwon-Hyung Lee, Cheol-Ho Park, In-Do Chung, Jae-Beom Choi
