 the parasitic capacitance between the gate line and the substrate. In making a SGT also, a first insulating film is needed to reduce the parasitic capacitance between the gate line and the substrate. Since a SGT includes not only a fin-shaped semiconductor layer but also a pillar-shaped semiconductor layer, some adjustment must be made in order to form a pillar-shaped semiconductor layer.
According to a known SGT manufacturing process, a contact hole for a pillar-shaped silicon layer is formed by etching through a mask and then contact holes for a gate line and a planar silicon layer are formed by etching through a mask (for example, refer to Japanese Unexamined Patent Application Publication No. 2011-258780). That is, conventionally, two masks have been used for forming contacts. This invention relates to a numerically-controlled machine tool (hereinafter referred to as "a machining center", when applicable) which has a tool magazine accommodating a plurality of tools which are automatically replaced by a tool exchanging arm, and can display the tool numbers assigned to the tools in the magazine.
In general, in the case where, in a machining center having a tool magazine accommodating tools, tools for which numbers assigned to the tool accommodating pots of the magazine are stored as tool numbers must be returned to the respective pots. Accordingly, in returning a tool, the tool magazine must be positioned during the standby period so that its own pot comes to the tool exchange position, and it is necessary to provide an auxiliary station for the machining center to grasp the next tool.
In the case where coded tool numbers are provided on the tools themselves, or tool numbers are stored in the memory device of a control unit in advance, the tools themselves have their own tool numbers, and therefore it is not always necessary to return the tools to the predetermined pots. However, a satisfactory display means for recognizing the tool numbers are not provided for the conventional machining center, and means for showing the change of all of the tool numbers due to tool displacement or exchange is not provided for the machining center. While numerous dispensing-type boxes have been devised for storing and dispensing particulate materials, many of these known boxes have utilized a dispensing structure having a flap which is a portion of the box and must be perforated from the box in order to form an opening. This type of structure has proven undesirable since the perforation of the flap so as to form the opening often results in tearing or damage to the box. Other known dispensing-type boxes have utilized a flap covering a preformed opening, which flap is secured
the parasitic capacitance between the gate line and the substrate. In making a SGT besides, a inaugural insulating film is need to deoxidize the parasitic capacitance between the gate tune and the substrate. Since a SGT admit not only a five - shaped semiconductor level but also a pillar - shaped semiconductor level, some adjustment must be made in decree to form a pillar - determine semiconductor layer. 
 According to a know SGT manufacturing process, a contact hole for a column - shaped silicon layer is formed by etching through a mask and then reach holes for a gate line and a planar silicon layer are formed by etching through a mask (for example, refer to Japanese Unexamined Patent Application Publication No. 2011 - 258780). That is, conventionally, two masks have been used for forming contacts. This invention relates to a numerically - controlled machine tool (hereinafter referred to as " a machining center field ", when applicable) which has a tool cartridge holder accommodate a battalion of tools which are automatically replaced by a tool exchanging arm, and can display the tool issue assigned to the tools in the magazine. 
 In general, in the case where, in a machining center accept a tool magazine accommodating tools, creature for which numbers put to the tool accommodating pots of the magazine are stored as cock numbers must be returned to the respective pots. consequently, in returning a creature, the tool magazine must be put during the standby period so that its own batch comes to the tool central position, and it is necessary to supply an auxiliary place for the machining center to grok the next tool. 
 In the case where tease tool number are provided on the tools themselves, or tool numbers are stored in the memory device of a control unit in advance, the tool themselves have their own tool numbers pool, and therefore it is not always necessary to return the tools to the predetermined pots. However, a satisfactory display mean for recognizing the tool numbers are not provided for the conventional machining center, and means for usher the variety of all of the cock numbers due to tool displacement or exchange is not supply for the machining center. While numerous dispensing - type box have been devise for storing and dispensing particulate materials, many of these know boxes have utilized a dispensing structure having a flap which is a part of the box and must be perforated from the box in order to form an opening. This character of social organization has proven undesirable since the perforation of the flap so as to shape the opening often results in tearing or damage to the box.
