首先，该领域存在资本与技术的双重壁垒。建设一条先进的晶圆制造产线需要上百亿美元的投资。其中的核心设备，如ASML的EUV光刻机、应用材料的刻蚀机等，是高度复杂的技术产品。ASML是全球唯一的EUV光刻机供应商，其市场地位使其成为“半导体供应链中最不可替代的公司”之一。这些设备的研发需要长期的资本投入、专业人才和精密的供应链支持，形成了其他商业模式难以在短期内复制的竞争壁垒。

Likewise, attempting to set up translations repeatedly resulted in "it just doesn't load the translation", and I had no idea what step in the build process I had missed. (As far as I can tell, translations simply don't work in the "latest" version (which is the default) of the Flatpak SDK. Selecting a different version, such as "48", magically works.)，更多细节参见新收录的资料
