This Chinese New Year just passed will be an unforgettable Spring Festival for all Chinese people. People had no time to celebrate the coming of the Year of 2020 before a sudden attack of new crown pneumonia, which has completely broken the festive atmosphere that should have been for this.

On January 30th, 2020, the WHO (World Health Organization) has announced that Wuhan pneumonia, the new type of coronaviruses, is an Public Health Emergency of International Concern (PHEIC).
ALD 和 CVD 是有助于在基板上沉积薄膜的薄膜沉积技术。两种技术之间的主要区别在于它们沉积薄膜的方式。ALD 和 CVD 之间的主要区别在于原子层沉积 (ALD) 一次沉积一个原子层的薄膜，而 CVD 可以沉积厚度范围更广的薄膜。
