For applications relying on non-equilibrium dopant activation, the extra thermal budget due to the slow ramp down could be a concern for deactivation. Alternatively, LSA uses a single narrow laser beam to heat the wafer surface from substrate temperature to the peak annealing temperature. The full width at half maximum of the laser trace is about mm wide, and can thus be resolved spatially with the x-ray microbeam of 15 m (Figure 1b). The 1st RTA (200~300C) forms Ni-rich silicide, and the 2nd RTA (400~500C) after selective etch of un-reacted Ni forms the desired low resistance NiSi phase. The full width at half maximum of the laser trace is about mm wide, and can thus be resolved spatially with the x-ray microbeam of 15 m (Figure 1b). Within this profile the polymer film reaches different peak temperatures, and the sweeping speed determines the dwell time at a specific temperature. The temperature dependence of reflectance at short wavelengths was used to determine the in-situ dynamic temperatures during CO2 LSA. [1] Alan G.

Figure 1a schematically shows the laser spike annealing procedure, where a focused laser beam from a 120 W infrared CO2 laser (=10.6 m) is swept across the sample. Previous studies have shown that such configuration has benefits of reduced pattern density effect compared to short wavelength with near normal incidence. The metal begins to oxidize internally. In advanced FinFET flow where contacts are formed after source/drain activation and gate stack, low thermal budget process is beneficial to minimize dopant deactivation and unintentional gate work function shift. This opens new opportunities for short time scale annealing. By keeping the laser spike duration very short (0.1-100 milliseconds), the technique is hypothesized to be short enough to avoid degradation of the GaN lattice itself. Laser processing applications that leverage laser scan heads are especially susceptible to errors from thermal loads. Thermoreflectance imaging results were compared with previous results, and show good agreements with direct Pt thermistor measurements and simulations results in both space and time. [1] Alan G.

In this blog post, well focus on the annealing process, and look at the advantages LSA has over conventional, lamp-based thermal annealing, and why LSA is a better solution that results in a stronger foundation for advanced logic and memory devices. Laser-annealing technology is about four decades old, but was generally considered to be incapable of handling the spatial nonuniformities on a semiconductor wafer full of varying device geometries. Because we understand the importance of improving within-die and die-to-die uniformity in high volume manufacturing, weve focused tool capabilities that monitor and control peak anneal temperature to reduce pattern dependency. FIGURE 2 compares the temperature (T) profiles between laser and flash systems for the same peak surface temperature (Tpk) and dwell time (tdwell defined as the full-width-half-maximum duration when a fixed point on the wafer sees the laser beam or flash pulse). A key aspect of achieving beam uniformity resides in the technology that enables the illumination source to compensate for the variations in surface absorption across different circuit features on a wafer. In conventional RTA, this requires T > 750C; such high T would lead to morphology degradation, excess diffusion, and higher resistivity. "We take the pseudo-Gaussian beam that comes out of the laser and we shape it into a rectangle with extremely good uniformity throughout," Talwar said. The surface will look a little darker to you, the thicker the oxide layer gets the darker the surface will be.
