摘要： Provided is a method of manufacturing a nano-sized MTJ cell in which a contact in the MTJ cell is formed without forming a contact hole. The method of forming the MTJ cell includes forming an MTJ layer on a substrate, forming an MTJ cell region by patterning the MTJ layer, sequentially depositing an insulating layer and a mask layer on the MTJ layer, exposing an upper surface of the MTJ cell region by etching the mask layer and the insulating layer at the same etching rate, and depositing a metal layer on the insulating layer and the MTJ layer.

摘要： A layer-by-layer etching apparatus and an etching method using a neutral beam which enables to control etching depth to an atomic level by controlling the etching of each atom of a material layer to be etched under precise control of the supply of an etching gas and irradiation of the neutral beam and enables to minimize etching damage. In the layer-by-layer etching method, a substrate to be etched, on which a layer to be etched is exposed, is loaded on a stage in a reaction chamber. An etching gas is supplied into the reaction chamber to adsorb the etching gas on the surface of an exposed portion of the layer to be etched. Excessive etching gas remaining after being adsorbed is removed. A neutral beam is irradiated on the layer to be etched on which the etching gas is adsorbed. Etch by-products generated by the irradiation of the neutral beam is removed.

摘要： Thinning and dicing substrates using inductively coupled plasma reactive ion etching (ICP RIE). When dicing, a hard photo-resist pattern or metal mask pattern that defines scribe lines is formed on a sapphire substrate or on a semiconductor epitaxial layer, beneficially by lithographic techniques. Then, the substrate is etched along the scribe lines to form etched channels. An etching gas comprised of BCl3 and/or BCl3/Cl2 gas is used (optionally, Ar can be added). Stress lines are then produced through the substrate along the etched channels. The substrate is then diced along the stress lines. When thinning, a surface of a substrate is subjected to inductively coupled plasma reactive ion etching (ICP RIE) using BCl3 and/or BCl3/Cl2 gas, possibly with some Ar. ICP RIE is particularly useful when working sapphire and other hard substrates.

摘要： A neutral beam-assisted atomic layer chemical vapor deposition (ALCVD) apparatus is provided for uniformly depositing an oxide layer filling a planarization layer or a trench to increase uniformity and density of the oxide layer using neutral beams generated by a neutral beam generator without a seam or void occurring in an atomic layer deposition (ALD) or ALD-like chemical vapor deposition (CVD) process, thereby solving problems on the void or seam and low density occurring when a high-density planarization layer or a shallow trench having a width of 65 nm or less is formed, and improving a next generation oxide layer isolation process. The neutral beam-assisted ALCVD apparatus includes: an ALCVD apparatus, which deposits an oxide layer in order to form a pattern in a semiconductor substrate; and a neutral beam generator, which converts ion beams to neutral beams in order to remove a seam or void in the oxide layer deposited between the patterns, and applies the neutral beams to the oxide layer deposited to form the pattern.
