These machines, which can cost over a hundred million euros, use ultraviolet light to etch intricate circuits onto silicon wafers.

这些造价逾亿欧元的机器，利用紫外线圆上刻蚀出复杂的电路。

The basic process of semiconductor manufacturing: including the whole process of semiconductor manufacturing, such as wafer preparation, thin film preparation, doping, etching a nd other processes.

半导体制造的基本流程：括半导体制造的全过程，如圆制备、薄膜制备、掺杂、刻蚀等。

The nanoporous structure was prepared on the surface of the platinum microelectrode by electrochemical etching, and then graphene oxide was deposited on the prepared nanoporous electrode by electrochemical deposition.

纳米多孔结构通过电化学刻蚀法铂微电极表面制备，随后利用电化学沉积法将氧化石墨烯沉积制备好的纳米多孔电极上。

In process positions, one needs to master the entire process of semiconductor manufacturing, including wafer preparation, thin film preparation, doping, etching and other processes to ensure product quality and yield.

岗位上，需要掌握半导体制造的全过程，括圆制备、薄膜制备、掺杂、刻蚀等，以保证产品的质量和良率。
