WebAug 1, 2005 · The fluorine implant is a 10 keV F + implant with a dose of about 1 × 10 15 ions/cm 2 at a 0° tilt. The carbon implant is a 6 keV C + implant with a dose of about 1 × 10 15 ions/cm 2 at a 0° tilt. The boron USJ implant is a 500 eV B + implant with a dose of about 4×10 14 ions/cm 2 at a 0° tilt. All implants were preformed on an Applied ... WebThe two implant tool types used were an Axcelis Optima MD implanter and a Varian E500 implanter. Implant conditions were chosen as follows based on experimentation and comparison of common processes among multiple manufacturing facilities utilizing several tool types: Boron11 at 100 keV energy, 1.0e14 ion/sq dose, 35° tilt, and 0° twist.

WebJan 1, 1987 · Plot of subthreshold slope vs implant energy for boron implant with dose of 3.25 1013 cm-2. The subthreshold slope decreases as the implant energy increases. This suggests that the interface trap density depends on the surface dopant concentration rather than on the total implanted dopant dose. E.

WebOct 1, 1977 · The ion implants were "B', BFZ', or 'r'; all were implanted at room temperature. If the samples were implanted with no protective screen, a 1000 A film of pyrolytic Si02 was deposited at low temperature over the implanted area to prevent any outdiffusion of the boron during the post-implant anneal. Webimplant energies. Each combination was designed to test for something, such as the effect of fluorine after B was implanted or the F damage before B was implanted. The wafers from each group received a spike anneal at 1075°C. The resulting boron profiles after implant and after spike anneal were obtained by SIMS analysis. Sheet resistance was ...
