Abstract

The in-situ phosphorus-doped polysilicon (IDP) emitter technique has been developed to form narrow and flat emitter region. One major problem to form the IDP process was found to be hFE fluctuation control. We revealed the cause and mechanism of the hFE variation and indicated the effective method of improving the device characteristics. It is concluded that the polySi/Si interface condition affect a lot on crystallization process of amorphous-silicon to polysilicon, which results in a changes of stress at the emitter layer.
