Novel process for the electrodeposition of Si thin film from ionic liquid electrolyte has been developed and the initial stage of the deposition process was investigated using EQCM, TEM, and Raman Spectroscopy. It was found that amorphous Si was electrodeposited while a certain amount of ionic liquid was included in the films. Moreover, uniform array of Si nanodots was successfully electrodeposited using 150 nm diameter dot array patterns fabricated by UV nanoimprinting lithography.

提出了从离子液体电解液中电沉积硅薄膜的新工艺，并用EQCM、TEM和拉曼光谱对沉积过程的初始阶段进行了研究。结果表明，当薄膜中含有一定量的离子液体时，可以电沉积出非晶态硅。此外，利用紫外光刻蚀技术制备了直径为150 nm的点阵列图案，成功地电沉积了均匀的硅纳米点阵列。
