| titleOfInvention | Semiconductor device comprising a ferroelectric memory element with a lower electrode provided with an oxygen barrier |
| abstract | The invention relates to a semiconductor device comprising a semiconductor body (3) with a semiconductor element (1) with an electrically conducting region (5) on which a capacitor (2) forming a memory element is present with a lower electrode (11), an oxidic ferroelectric dielectric (12), and an upper electrode (13), which lower electrode (11) makes electrical contact with the conducting region (5) and comprises a layer with a conductive metal oxide (112) and a layer (111) comprising platinum. The layer with the conductive metal oxide (112) acts as an oxygen barrier during manufacture. The invention also relates to a method of manufacturing such a semiconductor device. According to the invention, the device is characterized in that the layer comprising platinum (111) contains more than 15 atom % of a metal capable of forming a conductive metal oxide, and in that the layer (112) with the conductive metal oxide is present between the layer (111) comprising platinum and the ferroelectric dielectric (12). A good electrical contact between the lower electrode (11) and the conducting region (5) after manufacture is achieved thereby. |
