Therefore, the content related to the material evaluation results in the paper should be excluded. The following contents should be corrected.&lt;/p&gt;&lt;p&gt;The last sentence in the abstract section, “The damage to Mo&lt;sub&gt;2&lt;/sub&gt;C …,” should be removed.&lt;/p&gt;&lt;p&gt;In paragraph 3 of the “Introduction” section, the last 2 sentences “To observe the effect of the …,” should be removed. This should have been written as “In addition, the radical density which can represent the value in an actual mass production process environment, was measured using a quadrupole mass spectrometer (QMS).”&lt;/p&gt;&lt;p&gt;The content in Section 2.2 “Surface damage analysis” is incorrect and should be excluded. It should have been written in the “Discussion” section below.&lt;/p&gt;&lt;p&gt;: ″Inside EUV lithography equipment, the EUV beam is reflected off (or passes through) various EUV optical components such as multilayer mirrors, reticles, and pellicles before reaching the photoresist (see Figure 9). As the process cycle is repeated, surface of the components can be damaged by EUV-induced H&lt;sub&gt;2&lt;/sub&gt; plasma, potentially reducing the overall process reliability. This suggests that H&lt;sub&gt;2&lt;/sub&gt; plasma durability evaluations are needed for all EUV components within the EUV lithography equipment. Nevertheless, several factors make it challenging to conduct such damage evaluation:&lt;/p&gt;&lt;p&gt;1. It is difficult to use actual mass-production equipment for damage evaluation,&lt;/p&gt;&lt;p&gt;2. The cost of using high power EUV sources comparable to mass-production equipment for setting up evaluation systems is very high,&lt;/p&gt;&lt;p&gt;3. Using low-power EUV sources cannot generate a suitable density of H&lt;sub&gt;2&lt;/sub&gt; plasma for evaluation.&lt;/p&gt;&lt;p&gt;The evaluation system in this study uses ICP to generate a H&lt;sub&gt;2&lt;/sub&gt; plasma environment similar to EUV lithography at relatively low cost. Additionally, it enables accelerated life testing (ALT) with electron density control, making it a valuable option for addressing the previously mentioned issues.&lt;/p&gt;&lt;p&gt;Damage to samples can be examined using various methods. For relatively large surface damages such as blisters, identification with a microscope or even with the naked eye may be sufficient. The extent of surface etching on EUV components caused by H&lt;sub&gt;2&lt;/sub&gt; plasma can be measured by a change in weight using a calibrated scale. However, the weight differences before and after H&lt;sub&gt;2&lt;/sub&gt; plasma exposure are often smaller than the measurement uncertainty of the scale. Therefore, field-emission scanning electron microscopy (FE-SEM) is generally more suitable for damage analysis.

However, back grinding during the chip fabrication generally results in ≈70% of single-crystal SiC being wasted, leading to the high cost of SiC chips. In order to improve the utilization, single-crystal SiC on polycrystal SiC (SoP-SiC) is bonded. The challenge to achieve excellent bonding interfaces for such a system is the heterogeneous surface of polycrystals in which those grains with different orientations usually have different physical and chemical properties, making it difficult to achieve sufficiently smooth surfaces for bonding. Here, ion beam etching (IBE) is employed to activate the surface of polycrystal and single-crystal SiC and achieve high bonding strength (up to ≈20 MPa) after annealing in the atmosphere. Sub-nanometer-scale electron microscopy and energy spectroscopy analysis showing the IBE method can effectively inhibit the formation of silicon oxide at the bonding interface, which is expected to reduce the interface thermal resistance according to the phonon spectrum analysis.
