Abstract:
PURPOSE: A method of forming a resistor in a semiconductor device is provided to obtain the resistor without the degradation of a capacitor due to a high temperature by performing a low temperature process using P or B doped poly Si1-xGex. CONSTITUTION: A doped poly Si1-xGex layer is formed on a substrate. A resist with a doped poly Si1-xGex pattern(120a) is formed by patterning selectively the doped poly Si1-xGex layer. The doped poly Si1-xGex layer is doped with P or B. The doped poly Si1-xGex layer is formed by using an ALD(Atomic Layer Deposition) or a CVD(Chemical Vapor Deposition) in a temperature range of 350 to 500°C.

PURPOSE: A method for fabricating a semiconductor device is provided to control generation of metal oxide caused by a subsequent annealing process and to improve surface morphology of a metal layer, by oxidizing the metal layer at a temperature lower than that of the annealing process before the metal layer is annealed in an oxygen atmosphere. CONSTITUTION: The metal layer(4a) is formed on a semiconductor substrate. The metal layer is oxidized at the first temperature so that the upper portion(5) of the metal layer is changed to be a mixed phase of metal and oxygen constituting the metal layer. The metal layer having the metal-oxygen mixed phase is annealed at the second temperature higher than the first temperature in an oxygen atmosphere.

Abstract:
The present invention relates to a semiconductor device manufacturing method which forms a thin film on a substrate including a first region and a second region. A gate insulation film is formed on the thin film. A lower electrode film is formed on the gate insulation film. The gate insulation film is exposed at the second region by removing a part of the lower electrode film positioned at the second region. Nitrogen is injected to the part of the thin film positioned at the exposed gate thin film or under the same. An upper electrode film is formed at the lower electrode film remaining at the first region, and the exposed gate insulation film part. A first gate structure and a second gate structure are respectively formed at the first and second regions by partially removing the upper electrode film, the lower electrode film, the gate insulation film, and the thin film.
