    摘要: A method of forming a titanium nitride layer by an atomic layer deposition process using a batch-type vertical reaction furnace is described wherein a first source gas including a titanium precursor is provided onto substrates loaded in a process chamber for a first time period; a first purge gas is introduced into the process chamber for a second time period shorter than the first time period; a second source gas including nitrogen is provided onto the substrates for a third time period substantially identical to the first time period; and, a second purge gas is introduced into the process chamber for a fourth time period substantially identical to the second time period. Titanium nitride layers having uniform thickness and good step coverage may thus be formed while realizing a greatly reduced manufacturing time.

    摘要: In a method of manufacturing a capacitor including a hemispherical grain (HSG) silicon layer, after forming a storage electrode electrically coupled to a contact region of a substrate, the HSG silicon layer is formed on the storage electrode by providing a first gas including silicon and a second gas onto a surface of the storage electrode with a volume ratio of about 1.0:0.1 to about 1.0:5.0. A dielectric layer and a plate electrode are sequentially formed on the HSG silicon layer. A grain size of the HSG silicon layer may be easily adjusted and abnormal growths of the HSG at a lower portion of the storage electrode may be suppressed. Therefore, the HSG silicon layer may be uniformly formed on the storage electrode, and a structural stability of the storage electrode may be improved to prevent electrical defects of the capacitor.

    摘要: In a capacitor having a high dielectric constant, the capacitor includes a cylindrical lower electrode, a dielectric layer and an upper electrode. A metal oxide layer is formed on inner, top and outer surfaces of the lower electrode as the dielectric layer. A first sub-electrode is formed on a surface of the dielectric layer along the profile of the lower electrode and a second sub-electrode is continuously formed on the first sub-electrode corresponding to the top surface of the lower electrode, so an opening portion of the lower electrode is covered with the second sub-electrode. The first and second sub-electrodes include first and second metal nitride layers in which first and second stresses are applied, respectively. Directions of the first and second stresses are opposite to each other. Accordingly, cracking is minimized in the upper electrode with the high dielectric constant, thereby reducing current leakage.
