1. A micro-electro-mechanical system (MEMS) package, comprising:
a base substrate, with an MEMS element provided on a surface of the base substrate;
a lid being spaced apart from the MEMS element provided on the base substrate and covering the MEMS element;
a side sealing member provided on a side surface of the base substrate and a surface of the lid, said side sealing member of a material composition and positioned on, and spanning between, the side surface of the base substrate and on the surface of the lid to hermetically seal the MEMS element from an external environment; and
a thin hydrophobic layer which covers part of the side sealing member exposed to the external environment, said hydrophobic layer of a composition and applied to the side sealing member to substantially prevent moisture and other gas from passing through the side sealing member.
