Abstract: In a method of cleaning a photo mask, the photo mask is placed on a support such that a pattered surface faces down, and an adhesive sheet is applied to edges of a backside surface of the photo mask.

Abstract: A salt spray resistant structure of fan motor assembly includes a silicon steel sheet assembly, an insulation support assembly and an encapsulation layer. An inner side of the silicon steel sheet assembly defines a connection hole. A winding assembly is wound on the silicon steel sheet assembly and electrically connected with a circuit board. A first extension section protrudes from the silicon steel sheet assembly into the connection hole to cover a part of the inner side. A bearing cup covers the other part of the inner side. The encapsulation layer encapsulates the insulation support assembly, the winding assembly, the silicon steel sheet assembly and the circuit board so as to achieve salt spray resistant effect.

Abstract: A method includes placing a photomask having a contamination on a surface thereof in a plasma processing chamber. The contaminated photomask is plasma processed in the plasma processing chamber to remove the contamination from the surface. The plasma includes oxygen plasma or hydrogen plasma.

Abstract: A series fan structure with multistage frame body includes a first main body, a second main body, a first frame and a second frame. The first main body has a first fan frame having a first opening and a second opening. The second main body is correspondingly serially connected to the first main body. The second main body has a second fan frame having a third opening and a fourth opening. The third opening corresponds to the second opening. The first frame is correspondingly serially connected to one side of the first fan frame with the first opening. The first frame and the first fan frame together define a first flow passage. The second frame is correspondingly serially connected to one side of the second fan frame with the fourth opening. The second frame and the second fan frame together define a second flow passage.

Abstract: A reinforced fan frame structure includes a frame body and at least one metal ring. The frame body has a seat portion with a centered bearing cup axially forward extended from the seat portion. The metal ring is integrally associated with the seat portion and has an inner circumferential edge facing toward the bearing cup. With the metal ring integrally associated with the seat portion of the frame body, it is able to effectively control the deformation and the flatness of the seat portion and accordingly, effectively upgrade the overall structural strength of the seat portion.
