Embodiment 1

[0062] 100 parts of acrylic (ester) polymer (weight average molecular weight: 700,000), 200 parts of polyethylene Diol 200 dimethacrylate (trade name: NK Ester 4G, manufactured by Shin-nakamura Chemical Corporation), 3 parts of polyisocyanate compound (trade name: "Colonate L", manufactured by NIPPON POLYURETHANE INDUSTRY CO., LTD. ) and 3 parts of benzyl dimethyl ketal (trade name: Irgacure 651, manufactured by Ciba Specialty Chemicals Inc.) as a photopolymerization initiator to prepare an ultraviolet-curable resin composition A.

[0063] Separately, in a 500 ml three-necked flask-type reactor equipped with a thermometer, a stirrer, a nitrogen inlet tube and a reflux condenser, 73 parts of 2-ethylhexyl acrylate, 10 parts of n-butyl acrylate, 15 parts of N,N - Dimethacrylamide, 5 parts of acrylic acid and 0.15 parts of 2,2'-azobisisobutyronitrile and 100 parts of ethyl acetate as polymerization initiators to obtain 200 g. Then, nitrogen gas was introduced into the reactor, an...

Embodiment 2

[0080] Resin composition A and pressure-sensitive adhesive solution A were prepared in the same manner as in Example 1.

[0081] The pressure-sensitive adhesive solution A described above was spread on the release-treated surface of a spacer made of a continuous length of polyester film (thickness: 38 microns; width: 250 mm) and then dried. The ester film was treated with a silicone-based release agent on one side to a dry thickness of 15 microns. Then, a continuous length of polyester film (thickness: 25 μm; width: 250 mm) was laminated as a support material on the adhesive layer thus prepared. The above-mentioned ultraviolet-curable resin composition A was then spread on the film to a thickness of 40 micrometers to provide a resin layer. Then, the surface of the resin layer was laminated with a protective film A made of a polyester film (one side of which had been treated with a silicone-based release agent) in such a way that the protective film A was peeled off. The surf...

Embodiment 3

[0119] Resin composition A and pressure-sensitive adhesive solution A were prepared in the same manner as in Example 1.

[0120] The above-mentioned pressure-sensitive adhesive solution A was spread on the release-treated surface of a spacer B made of a continuous length of polyester film (thickness: 38 μm; width: 250 mm), and then dried. The polyester film was treated with a silicone-based release agent on one side to a dry thickness of 15 microns. Then, a continuous length of polyester film (thickness: 25 μm; width: 250 mm) was laminated as a support material on the adhesive layer thus prepared. The above-mentioned ultraviolet-curable resin composition A was then spread on the film to a thickness of 40 micrometers to provide a resin layer. Then, the surface of the resin layer was laminated with the same spacer B used thereon in such a way that the release-treated surface of the spacer B was in contact with the resin layer to form a laminated sheet.

[0121] Then, use ultra...

Abstract

A cleaning member which does not contaminate a substrate processing apparatus with an ionic impurity when conveyed into the apparatus for removing foreign materials within the apparatus is disclosed. A cleaning member which does not contaminate a substrate processing apparatus with a metallic impurity when conveyed into the apparatus for removing foreign materials within the apparatus is also disclosed. Specifically, a cleaning sheet characterized in that a cleaning layer wherein pure water extraction amounts (extracted for one hour while boiling at 120 1 / 2 C) of F<->, Cl<->, Br<->, NO2<->, NO3<->, PO4<3->, SO4<2->, Na<+>, NH4<+>, and K<+> are respectively 20 ppm or less is provided on one surface of a supporting body and an adhesive layer is provided on the other surface is disclosed. A cleaning sheet characterized in that a cleaning layer wherein respective contents of Na, K, Mg, Al, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn and compounds thereof are 5 ppm (mug / g) or less when calculated in terms of respective metal elements is provided on one surface of a supporting body and an adhesive layer is provided on the other surface is also disclosed.

Description

technical field [0001] The present invention relates to a cleaning sheet for various substrate processing devices susceptible to foreign substances, such as devices for manufacturing or testing semiconductors, flat panel displays, and printed circuit boards, and a method of cleaning substrate processing devices using the sheet , and a substrate processing device cleaned by the cleaning method. Background technique [0002] In various substrate processing apparatuses, various conveying systems and substrates are conveyed in physical contact with each other. In this process, when foreign matter is attached to the substrate or the delivery system, then the substrate is subsequently contaminated in turn. This makes it necessary to periodically stop the operation of the device for cleaning, making the operation less efficient or requiring more labor. [0003] In order to solve these problems, a method including conveying a substrate on which an adhesive material is fixed, by cl...
