The CaF2 window would be the laser exit of your DUV lithography device as well as its sealing part. Bearing the irradiation, significant strain, and discharging pollutants, the window is not difficult to damage and directly deteriorate the effectiveness and dependability with the laser. In this paper, contemplating the effects of the above aspects, two regular small-phrase damages towards the CaF2 window - significant Electrical power induced damage and pollutant-induced injury are studied quantitatively. Using an experimental structure, theoretical calculation, characterization Assessment, and numerical simulation, we located that the harm induced by higher-Vitality irradiation is dominated by defect propagation for the Original stage. Within the later on phase, it can be dominated by warmth and thermal anxiety with thermal melting and evenly dispersed microcracks of one∼ten µm in dimension.
The calculated band structures of BaF2 for the different pressures utilized from the experiments are demonstrated in Fig. 6. Table 1 summarizes the Strength gaps amongst the valence and conduction bands (valence‒conduction bandgap), the Main‒conduction bandgap, along with the core‒valence bandgap. While in the cubic stage, in the event the applied tension is fewer than three.7 GPa, the valence‒conduction bandgap appears to be steady. The valence‒conduction bandgap a little bit boosts with escalating stress within the orthorhombic stage. Nevertheless, the conduction and valence bands will not look to drastically flatten even as the crystal is compressed. A significant necessity for CL is that the valence−conduction bandgap ought to be larger compared to core−valence bandgap so which the CL photons will not be reabsorbed by the fabric. Band gap control and band structure manipulation by means of uniform and uniaxial stress software ended up Formerly shown in hexagonal lithium BaF₂ Crystal calcium aluminum fluoride (LiCaAlF or LiCAF)26 and lithium yttrium fluoride (YLiF4)27 laser supplies. Uniform volume compression at expanding pressures as many as fifty GPa monotonically enhanced the valence−conduction bandgap of LiCAF due to the flattening of the conduction band.
