A method of fixing a taper implant to a receiving member includes providing a taper implant having a frusto-conical outer surface, a projecting portion connected to a larger diameter end and a smaller diameter end. The article has a parallel plate burst strength of at least 190 inches of water, with the film having a thickness of from 1 to 2. The package is suitable for packaging circuits containing rechargeable batteries and for packaging other electronic devices. The image reconstituting unit reconstitutes a medical image by performing a back projection process on projection data that is generated by use of the counting information stored in the counting information storage unit. The method includes the steps of: providing a substrate; forming a dummy gate on the substrate; forming a contact etch stop layer on the dummy gate and the substrate; performing a planarizing process to partially remove the contact etch stop layer; partially removing the dummy gate; and performing a thermal treatment on the contact etch stop layer.
