High emitter profile
Webphase (omitting the drive-in phase) and a high throughput oxidation by stacking the wafers. We study the achievable charge carrier concentration profiles, the emitter recombination properties, the oxide growth, and the combination with laser doping in comparison to a reference state-of-the-art high temperature process route.

WebAbstract: Self-aligned heterojunction bipolar transistors with a high-low emitter profile consisting of a heavily doped polysilicon contact on top of a thin epitaxial emitter cap have been fabricated. The low doping in the single-crystal emitter cap allows a very high dopant concentration in the base with low emitter-base reverse leakage and low emitter-base … Web294 Chapter 8 Bipolar Transistor τB and D B are the recombination lifetime and the minority carrier (electron) diffusion constant in the ba se, respectively. The boundary conditions …
WebGaussian profile p +-type emitters also presented high emitter collection efficiencies, even if they are highly doped and shallow. It was found that only if the optimized emitter sheet resistivities for each surface doping level is considered, the collection efficiency of the moderated doped emitters are slightly higher than the highly doped ones. Webemitter profiles with defined shallow FSF in the range of 40-80 nm. Fig. 3. (left) Increase of the doping incorporation by increasing the HCl flow; (right) concept for high efficiency p-type solar cells with epitaxial selective emitter by plasma texturing, rear side passivation and local epitaxial BSF.
Webour knowledge, this leads to the first emitter developed so far that is capable of addressing the three main green- house gases, CO 2 ,H 2 O, and CH 4 , in the 2 μm region.
