Melt Annealing

We have demonstrated the possibility for epitaxial regrowth of crystalline SiC by laser melt annealing. The quality of the recrystallization is analyzed by XTEM, EELS, electron diffraction and XRD. The annealing guarantees a uniform activation achieved both in melting and solid phase. Carbon graphitization on the top surface and a crystallized silicon layer below is observed as an effect of the high temperature and the melting phase.

Different Types

ABSTRACTThe rate of solid-phase epitaxial regrowth has been studied using time-resolved reflectivity in three different types of SiGe/Si epilayers amorphized by ion implantation. In two of these cases, the alloy epilayer contained either 12% or 20% Ge, and the amorphization depth was greater than the thickness (2000 Å) of the SiGe alloy layer. Time-resolved reflectivity measurements showed that the rate of regrowth was not constant in these two cases, but first decreased after passing the SiGe/Si interface, and then increased. The minimum regrowth rate occurred closer to the SiGe/Si interface in the epilayers with the larger Ge atomic fraction. In the third type of sample, the alloy epilayer thickness was ∼7μm, so that the initial epilayer (15% Ge) had the lattice constant of the bulk alloy. Furthermore, amorphization and regrowth occurred entirely within the relaxed alloy layer. In this case, the regrowth rate was constant. The composition dependence of the regrowth-rate transient in the strained layers is discussed in the context of a ‘critical-thickness’ model of strain relaxation.

Convergent Beam

A recent process technology to manufacture bipolar junction transistors utilizes polysilicon emitters. Polysilicon is deposited, appropriately doped to form both NPN and PNP transistors, and exposed to temperatures that result in grain growth. Since polysilicon is in contact with Si( 100) at the emitter, base, and collector (Fig. 1), solid phase epitaxial regrowth might also occur. Production runs with this structure occasionally produce transistors with low current gain. High and low gain NPN and PNP transistors were characterized by transmission electron microscopy.Vertical sections through NPN/PNP transistor arrays were made by the wedge technique, low-angle ion milled to electron-transparency, and viewed at 200 KV. The grain size of the polysilicon on oxide was recorded and estimated. The extent of epitaxial regrowth was quantified for each of the Si (100) contact areas. Convergent Beam Electron Diffraction (CBED) was used to confirm the orientation of the presumed regrown polysilicon.
