看看这句话有没有语病或者引起歧义：Laser processing is an efficient method to fabricate superhydrophobic surface which has attracted many attentions because of its multi-functions.

这句话有一些语法问题和用词不当的地方。修正后的版本如下：

Laser processing is an efficient method for fabricating superhydrophobic surfaces, which have attracted much attention due to their multifunctionality.
