Patent number: 8829644Abstract: In a non-volatile memory device and method of manufacturing the same, a device isolation pattern and an active region extend in a first direction on a substrate. A first dielectric pattern is formed on the active region of the substrate. Conductive stack structures are arranged on the first dielectric pattern and a recess is formed between a pair of the adjacent conductive stack structures. A protection layer is formed on a sidewall of the stack structure to protect the sidewall of the stack structure from over-etching along the first direction. The protection layer includes an etch-proof layer having oxide and arranged on a sidewall of the floating gate electrode and a sidewall of the control gate line and a spacer layer covering the sidewall of the conductive stack structures.Type: GrantFiled: November 5, 2013Date of Patent: September 9, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Jae-Hwang Sim, Keon-Soo Kim, Kyung-Hoon Min, Min-Sung Song, Yeon-Wook Jung

Patent number: 6147745Abstract: An exposure apparatus includes a frame member with a first stage having a substrate disposed thereon provided in a lower portion of the frame member. A leveling mechanism is provided for adjusting an orientation of the first stage. The exposure apparatus further includes a second stage positioned over the first stage and fixed to the frame member. A reticle is positioned on the second stage. An exposure area limiting mechanism is provided in the exposure apparatus and positioned over the second stage. The exposure area limiting mechanism defines an opening through which light is capable of passing during exposure for limiting an exposure area of the second stage. The exposure apparatus also includes an illumination system to irradiate light to the exposure area limiting means.Type: GrantFiled: November 16, 1998Date of Patent: November 14, 2000Assignee: Samsung Aerospace Industries, Ltd.Inventors: Yong-ki Kim, Deok-yong Ko, Joong-yeon Jeong, Hyung-seok Lee, Yeon-wook Jung

Patent number: 6067145Abstract: A light-exposing device for making a semiconductor device. A reticle has patterns to be exposed to light. A blind controls a light-exposing area of the reticle. An optical system between the blind and the reticle condenses light passing through the blind. Adjacent patterns on a reticle are consecutively projected by superimposing light-exposing energy. An extra optical system condenses light passing through the blind. The usable area of the reticle is maximized; the interval between patterns is not critical; and inferiority by either lack or excess of the exposure to light between the patterns is reduced.Type: GrantFiled: March 6, 1996Date of Patent: May 23, 2000Assignee: Samsung Aerospace Industries, Ltd.Inventor: Yeon-Wook Jung
