Abstract: A dual-structure tube vessel and a method of producing the tube vessel are disclosed. The dual-structure tube vessel includes a cylindrical vessel body and a neck integrated with the vessel body into a single structure, and further includes: a body partitioning sheet provided in the vessel body and partitioning the interior of the vessel body into two sections; and a neck partitioning sheet provided in the neck and partitioning the interior of the neck into two sections. The vessel body and the body partitioning sheet may be fabricated using three sheets of material or one sheet of material. Further, the body partitioning sheet has a width equal to an inner circumference of a larger one of the two sections of the vessel body. Further, each of the vessel body and the body partitioning sheet is made of a threefold laminated sheet with a polyethylene/aluminum/polyethylene layered structure.

Abstract: A method of fabricating a flash memory is provided. The method includes forming a tunneling insulating film, a charge storage film, and a blocking insulating film on a semiconductor substrate; performing High Temperature (HT) anneal for the resultant semiconductor substrate; and performing Low Temperature (LT) wet vapor anneal for the resultant semiconductor substrate.
