摘要:
A protocol converting apparatus (communication relay apparatus) relays communications between a cellular phone and an specific network (VPN) so that the cellular phone is connected to the VPN in which communication is performed by using an independently set dedicated address. The protocol converting apparatus has a data communication section that performs data communication with the cellular phone, a VPN connecting section that performs data communication with the specific network (VPN), a protocol converting section that converts a communication protocol of communication data, and an address authentication specifying section that specifies a destination of the communication data.

A separating apparatus according to the present invention includes a clamp for gripping an outer peripheral end of a supporting plate. The clamp grips the outer peripheral end of the supporting plate and separates the supporting plate from a wafer by gripping the supporting plate. This makes it possible to separate a supporting plate from a wafer without breaking the wafer. With this, a supporting plate can be separated from a wafer to which the supporting plate has been attached, without breaking the wafer.

摘要:
A treatment liquid permeation unit comprises: at least one vibration unit; and a vibration transmission unit for transmitting a vibration from the vibration unit. The vibration transmission unit is positioned between an adhesive with which a wafer is combined to a supporting plate or an adhesive adhered to a surface of the wafer and the vibration unit. A vibration from the vibration unit is transmitted via the vibration transmission unit. This promotes the treatment liquid for dissolving the adhesive to permeate the adhesive to which the treatment liquid is supplied. Therefore, the treatment liquid can more uniformly permeate the adhesive in a shorter time. This allows the treatment liquid for dissolving the adhesive to permeate the adhesive with which the wafer is combined to the supporting plate or to permeate the adhesive adhered to the surface of the wafer in a shorter time.

A wafer can be thinned without occurrences of dimples. A support plate 1 has a number of through holes 10. A circuit forming surface of a wafer 2 is adhered to one surface of the support plate by an adhesive member 4, and a dimple prevention member 3 having a thickness of 100 μm or more and having an adhesive layer 30 on one face is adhered to the other surface, thus the openings at both ends of the through holes 10 are blocked. The support plate is vacuum adsorbed to a support table through the dimple prevention member, and a non circuit-forming face of the wafer is ground/polished to thin the wafer. The dimple prevention member is stripped off, and a solvent is penetrated into the adhesive member through the through holes to detach the wafer from the support plate.

A planarizing coating method for filling a step between patterns formed on a board surface, includes the steps of: preparing at least two types of coating liquids different in non-volatile matter densities, first coating one of the coating liquids higher in density on the board surface, rotating the board so as to leave the one coating liquid inside the step and such that, at the same time, substantially none of the one coating liquid is left on a pattern crest of the patterns, subsequently coating another of the coating liquids lower in non-volatile matter density on the board surface, and rotating the board so that the coating liquid lower in density is left on a coating film comprising the one coating liquid higher in density and such that, at the same time, substantially none of the other coating liquid lower in density left on the pattern crest.
摘要:
A method for thinning a substrate and a method for manufacturing a circuit device which make it possible to prevent the pattern of penetrating holes of a supporting plate from being transferred to the surface of the substrate and prevent non-uniform grinding of the surface of the substrate from occurring. The supporting plate and the substrate are joined by using an adhesive layer, and a sheet is attached to the supporting plate. The surface of the supporting plate to which the sheet has been attached is mounted and fixed by attraction onto an attracting head. The surface of the semiconductor wafer on which no circuit device is formed is ground by a grinder in this state.
