Patent number: 7709377Abstract: A thin film including multi components and a method of forming the thin film are provided, wherein a method according to an embodiment of the present invention, a substrate is loaded into a reaction chamber. A unit material layer is formed on the substrate. The unit material layer may be formed of a mosaic atomic layer composed of two kinds of precursors containing components constituting the thin film. The inside of the reaction chamber is purged, and the MAL is chemically changed. The method of forming the thin film of the present invention requires fewer steps than a conventional method while retaining the advantages of the conventional method, thereby allowing a superior thin film yield in the present invention than previously obtainable.Type: GrantFiled: July 8, 2005Date of Patent: May 4, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Jung-hyun Lee, Dae-sig Kim, Yo-sep Min, Young-jin Cho

Patent number: 6752869Abstract: An atomic layer deposition (ALD) method, whereby an organometallic complex with a &bgr;-diketone ligand is chemically adsorbed onto a substrate and oxidized by activated oxygen radicals to deposit an atomic metal oxide layer on the substrate, uses reactive oxygen radicals generated using plasma and an organometallic complex having a &bgr;-diketone ligand as a precursor, which could not be used in a thermal ALD method using oxygen or water as an oxidizing agent, to address and solve the problem of the removal of organic substances using organometallic complexes with &bgr;-diketone ligands, thereby enabling diversification of the precursors for ALD and formation of excellent oxide films at low temperatures.Type: GrantFiled: June 4, 2002Date of Patent: June 22, 2004Assignee: Samsung Electronics Co., Ltd.Inventors: Jung-hyun Lee, Dae-sig Kim, Yo-sep Min, Young-jin Cho

Patent number: 6333066Abstract: A method for forming a PZT (lead zirconate titanate: Pb(ZrxTi1−x)O3) thin film using a seed layer is provided. In the method for forming a PZT thin film, PZT is grown on a PbO seed layer or a PZT seed layer of a perovskite phase formed by injecting excess Pb. The PbO seed layer or the PZT seed layer of a perovskite phase facilitates creation of perovskite PZT nuclei, thereby growing small and uniform PZT grains consisting of a perovskite phase.Type: GrantFiled: November 20, 1998Date of Patent: December 25, 2001Assignee: Samsung Electronics Co., Ltd.Inventor: Dae-sig Kim

Patent number: 6080593Abstract: A method of manufacturing a ferroelectric memory of MFS- or MFIS-type includes the steps of forming on a substrate an insulating layer for preventing reaction at an interface between a ferroelectric material and a silicon substrate, forming a ferroelectric layer on the insulating layer, reacting a material of the insulating layer with a material of the ferroelectric layer, to transform the insulating layer into part of the ferroelectric layer, and forming an electrode on the ferroelectric layer. Since the insulating layer is formed between a substrate and a ferroelectric material, undesirable reaction between the two substances is prevented. The insulating layer is completely absorbed into the ferroelectric layer due to diffusion during deposition of the ferroelectric layer, to form an MFS-type ferroelectric memory. When some of the insulating layer remains, the ferroelectric memory becomes an MFIS-type.Type: GrantFiled: July 28, 1998Date of Patent: June 27, 2000Assignee: Samsung Electronics Co., Ltd.Inventors: Dae-sig Kim, Il-sub Chung

Patent number: 5603169Abstract: A bubbler for solid metal-organic precursors is described. The bubbler includes a bubbler body, a carrier gas feed tube, an exhaust tube, a compressing plate and a pair of porous thin plates. A carrier gas is fed into a mass of metal-organic precursors through a feed tube which is connected with the bottom of the bubbler body. The exhaust tube is set away from the mass of metal-organic precursors and drains the carrier gas passing through the precursors. The compressing plate has many holes and is movable up and down along the wall of the bubbler body so that it may be positioned according to the amount of the precursors. The upper porous thin plate is located between the exhaust tube and the compressing plate, and the lower porous thin plate is located above the leading end of the feed tube, giving support to the mass of the metal-organic precursors. That is, the precursors are placed on the lower porous thin plate and there is a room between the lower porous thin plate and the bottom of the bubbler body.Type: GrantFiled: September 29, 1995Date of Patent: February 18, 1997Assignee: Samsung Electronics Co.
