The analysis was done using 3-D Silvaco/ATLAS simulation on a device with 50 nm thick buried oxide and 40 nm thick silicon film. The gate contact is p+ polysilicon and the gate oxide thickness is 5 nm. The base width (channel length) of the device is 80 nm and the separation between two bases (channel width) is 5 µm. The doping concentration of the body is 1017 cm-3.

FABRICATION OF BIPOLAR JUNCTION TRANSISTOR _1100232

consists of the n~ substrate and does not require an n+ buried layer or a highly doped substrate (Fig. 2,4)- Fourdifferent structures (layouts of the BJT,Fig. 3)...
With the DT and n+ buried layer in SiGe process, the parasitic vertical p-n-p BJT in the diode string was connected with a base-emitter- short configuration [8], which results in a lower substrate leakage current than that of the conventional P+/N-well diode in CMOS process.

BJT Fabrication - Final Buried Layer Window • After the remaining PR is stripped, the deposited oxide has an opening etched in the location specified by the buried layer mask. ELEC 3908, Physical Electronics: BJT Structure and Fabrication Page 15-9 BJT Fabrication - Buried Layer Implant • The buried layer is formed with a high density (dose) implant of n-type dopant, usually Phosphorous

  • The traditional junction isolation technique requires the p+ deep diffusion to be aligned to the n+ buried layer that is covered by a thick epitaxial layer. . Modern isolation techniques: oxide isolation.
