Abstract (en)

[origin: WO2004044994A2] The invention relates to a monolithically integrated vertical pin photodiode which is produced according to BiCMOS technology and comprises a planar surface (30) facing the light (h <) and a rear face (31), and anode connections (A1, A2) located across p areas (20, 21) on a top face of the photodiode. An i zone of the pin photodiode is formed by combining a low doped first p<-> epitaxial layer (10, d10) which has a maximum thickness of essentially 15ñm and a doping concentration of less than 5*10<14> cm<-3> and is placed on a particularly high doped p substrate (10), with a low doped second n<-> epitaxial layer (9) that borders the first layer (10) and has a doping concentration ranging substantially between 10<14> cm<-3> and 10<15> cm<-3>, an n<+> cathode (K) of the pin photodiode being integrated into said second layer (9). p areas (20, 21) delimit the second n epitaxial layer (9) in a latent direction while another anode-connecting area (A3) of the pin diode is provided on the rear face (31) in addition to the anode connections (A1, A2).
