摘要:
It is an object of the present invention to improve a factor which influences productivity such as variation caused by a characteristic defect of a circuit by thinning or production yield when an integrated circuit device in which a substrate is thinned is manufactured. A stopper layer is formed over one surface of a substrate, and an element is formed over the stopper layer, and then, the substrate is thinned from the other surface thereof. A method in which a substrate is ground or polished or a method in which the substrate is etched by chemical reaction is used as a method for thinning or removing the substrate.

An antenna used for an ID chip or the like is disclosed with planarized antenna unevenness and an IC chip having such the antenna with a flat surface is disclosed. Manufacturing an integrated circuit mounted with an antenna is facilitated. A laminated body formed by stacking a conductive film 11, a resin film 13, an integrated circuit 12, and a resin film 14 are rolled so that the resin film 14 is outside. Then, the laminated body is integrated in a roll form by softening the resin films 13, 14 by applying heat. By slicing the rolled laminated body along with the direction in which the rolled conductive film 31 appears in the cross section, an IC chip with antenna formed by the rolled conductive film 11 is formed.

An object is to provide a method for manufacturing a semiconductor device which suppresses an influence on a semiconductor element due to entry of an impurity element, moisture, or the like from outside even in the case of thinning or removing a substrate after forming a semiconductor element over the substrate. A feature is to form an insulating film functioning as a protective film on at least one side of the substrate by performing surface treatment on the substrate, to form a semiconductor element such as a thin film transistor over the insulating film, and to thin the substrate. As the surface treatment, addition of an impurity element or plasma treatment is performed on the substrate. As a means for thinning the substrate, the substrate can be partially removed by performing grinding treatment, polishing treatment, or the like on the other side of the substrate.

To provide a thin film integrated circuit at low cost and with thin thickness, which is applicable to mass production unlike the conventional glass substrate or the single crystalline silicon substrate, and a structure and a process of a thin film integrated circuit device or an IC chip having the thin film integrated circuit. A manufacturing method of a semiconductor device includes the steps of forming a first insulating film over one surface of a silicon substrate, forming a layer having at least two thin film integrated circuits over the first insulating film, forming a resin layer so as to cover the layer having the thin film integrated circuit, forming a film so as to cover the resin layer, grinding a backside of one surface of the silicon substrate which is formed with the layer having the thin film integrated circuit, and polishing the ground surface of the silicon substrate.

It is an object of the present invention to provide a method for manufacturing a semiconductor device, which is flexible and superiority in physical strength. As a method for manufacturing a semiconductor device, an element layer including a plurality of integrated circuits is formed over one surface of a substrate; a hole having curvature is formed in part of one surface side of the substrate; the substrate is thinned (for example, the other surface of the substrate is ground and polished); and the substrate is cut off so that a cross section of the substrate has curvature corresponding to a portion where the hole is formed; whereby a laminated body including an integrated circuit is formed. Further, a thickness of the substrate, which is polished, is 2 μm or more and 50 μm or less.

To provide a semiconductor device including a thinned substrate with high yield. After forming a protective layer in a predetermined portion (at least a portion covering a side surface of a substrate) of the substrate, grinding and polishing of the substrate are performed. In other words, an element layer including a plurality of integrated circuits is formed over one surface of the substrate, the protective layer is formed in contact with at least the side surface of the substrate, and the substrate is thinned (for example, the other surface of the substrate is ground and polished), the protective layer is removed, and the polished substrate and the element layer is divided so as to form stack bodies including a layer provided with at least one of the plurality of integrated circuits.

The present invention provides a new type wireless chip that can be used without being fixed on a product. Specifically, a wireless chip can have a new function by a sealing step. One feature of a wireless chip according to the present invention is to have a structure in which an integrated circuit is sealed by films. In particular, the films sealing the integrated circuit have a hollow structure; therefore the wireless chip can have a new function.
