Abstract:
PURPOSE: A semiconductor device which includes source/drain regions with a steep slope junction profile and a manufacturing method thereof are provided to perform a heat treatment process for diffusing impurities at low temperatures, thereby providing excellent junction leakage current properties. CONSTITUTION: A semiconductor substrate(1) is etched using a gate pattern as an etching mask. A pair of active trenches(19a,19b) is formed on the semiconductor substrate by being separated from each other. Epitaxial layers(21,25) are respectively formed within the activity trenches. The epitaxial layer is formed by successively laminating a first layer and a second layer. The first and second layers are formed into a semiconductor layer which has a lattice constant larger than the semiconductor substrate.

PURPOSE: A method for fabricating a non-volatile memory device including a self-aligned gate structure and a non-volatile memory device thereby are provided to prevent an error due to a contact hole by reducing height of an interlayer dielectric. CONSTITUTION: A tunnel dielectric layer(210) is formed on a semiconductor substrate(100). The first floating gate pattern is formed on the tunnel dielectric layer(210). A mold pattern is formed on the first floating gate pattern. A floating gate(300') is formed by removing the first floating gate pattern. An interlayer dielectric layer pattern(500) is formed by filling up a gap between the mold patterns. The mold pattern is removed by using the interlayer dielectric layer pattern(500) as an etch mask. An intergate dielectric layer(250) is formed on the exposed floating gate(300') between the interlayer dielectric layer patterns(500). A control gate(600) is formed by filling up a gap between the interlayer dielectric layer patterns(500) on the intergate dielectric layer(250).
Abstract:
PURPOSE: A method for manufacturing a semiconductor device is provided to ameliorate an etching delay phenomenon. CONSTITUTION: A photoresist pattern(14, 104) is formed on an etching object layer(12). Next, a polymer(16, 106) is formed with a unique thickness at side wall of the photoresist pattern(14, 104) by a plasma process, so that an etching speed of the etching object layer(12) is improved. A contact hole(108) is formed by etching the etching object layer(12) utilizing the photoresist pattern(14, 104) at which the polymer(16, 106) is formed. Thereby, an etching delay phenomenon can be ameliorated for forming the contact hole(108) or a trench.
Abstract:
PURPOSE: A method for forming a contact hole in a semiconductor devices is provided to increase overlap and alignment margins thereof. CONSTITUTION: A slot(108) is formed by etching a layer insulation film(104) with a predetermined depth. A polymer spacer is formed at a side wall of the slot. A contact hole is formed by etching an exposed area of the layer insulation film via the slot, so that a lower conductive film is exposed. Because a polymer spacer(110) is formed at a predetermined area of the layer insulation film, upper portion of the contact hole can be declined without changing limit margin. Thereby, the overlap margin to an upper conductive film can be increased. Otherwise, the limit margin of lower portion of the contact hole(112) is not increased according to the polymer spacer(110). Thereby, the alignment margin can be increased.
