Popis: | A key issue in modern microelectronics is to improve and optimise device performance and reliability without excessively increasing fabrication costs. In this paper we will show how it is possible to improve the reliability of single-polysilicon quasi self-aligned BJTs of an advanced 0.5/spl mu/m BiCMOS technology by means of base surface As compensation without any additional mask. By carefully optimising the process parameters it is possible to maintain unchanged the characteristics of the intrinsic transistor compared to the reference one (without compensation) with only a slight increase of the parasitic base resistance, as proven by extensive statistical measurements. Depending on the As dose an increase of the device lifetime by up to four orders of magnitude can be obtained. |
