Abstract: PURPOSE:To restrain the air from entering the inside of a heating chamber, by a method wherein a number of shield plates, with which inert gas within the heating chamber is restrained from flowing out at the outside of the title furnace, are formed in inlet and outlet pathways provided at the front and rear parts of the heating chamber, and a horizontal plate part is formed at the top end of each of the shield plates. CONSTITUTION:In the title furnace, circuit boards 19, on each of which electronic part are placed, are carried in and out under the condition that both sides thereof are supported by a chain conveyor. The circuit boards 19 are conveyed through an inlet pathways 15 and an outlet pathway 17 extended at the front and rear parts of a heating chamber 13 equipped with heaters 11, and the electronic parts are soldered on the circuit boards 19. The inside of the title furnace is filled with inert gas such as nitrogen and the inert gas prevents the oxidation of the circuit boards and the electronic parts.

Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a nonvolatile semiconductor memory in which recessed part can be prevented from being formed at a source line. SOLUTION: A polysilicon film 86 is removed by etching so that the polysilicon film 86 is left on the whole face of a source line formation region 88, and one part of a floating gate is patterned. That is, the regions removed are only removal regions 92, 94, and 96 on an element separation region which are removed by etching. Thus, the polysilicon film 86 and the polysilicon film which is a control gate can be laminated on the source line formation region 88. Therefore, the thickness of the film to be etched on the source line formation region 88 can be made the same as that on a region in which a storage element is formed. At patterning the remaining part of the floating gate and the control gate, a recessed part prevented from being formed due to the excessive etching of the source line formation region 88 is eliminated.
