WebChanneling can be reduced by a screening layer or by pre-amorphization. An amorphous layer, preferable silicon dioxide, can be deposited on the crystalline substrate to scatter the implanted ions. The pre-amorphization … WebNov 30, 2006 · Continuous downscaling of complementary metal-oxide semiconductor devices requires the manufacture of highly doped ultrashallow junctions. A preamorphizing implant (PAI) is commonly used in industrial processing in order to avoid unfavorable profile broadening and channeling tails during dopant atom implant in the ultralow energy regime …
5.2 Effect of Pre-amorphization
WebAug 1, 1991 · We have studied this for implants of 0.1–1 MeV B, Si, P, Ga, As, In, and Sb ions after annealing at 900°C using cross-sectional transmission electron microscopy. Pre-amorphization damage, also called category I dislocations, is observed if the total number of silicon atoms displaced by the implant exceeds a critical value before reaching the ...
