201131745 六、發明說明: 【發明所屬之技術領域】 本發明是有關記憶格及記憶格的製造方法。 【先前技術】 近年來,利用印刷技術來製造電子電路的技術(可印 刷電子機器)被開發。例如,在國際公開第 W02007/078 8 60號中提案一利用印刷技術來製造電晶體的 方法。 另一方面,即使切掉電源,資料也不會消失的非揮發 性記億體(例如快閃記憶體等)被開發。快閃記億體是利 用隧道電流等在被稱爲浮遊閘極的領域積蓄電子,根據在 浮遊閘極有無電子來變化電晶體的臨界値電壓,藉此記億 1與0的方式。而且最近有使用MRAM ( Magnetoresistive Random Access Memory )或 PCM ( Phase Change Memory )等各種電阻變化元件者被提案作爲ReRAM ( Resistivity Change Random Access Memory)。其一是在國際公開第 W0 2008/021 91 2號中記載有將奈米碳管作爲電阻變化元件 用的非揮發性記憶體。 【發明內容】 (發明所欲解決的課題) 電子機器有爲了記憶各種的資料而使用非揮發性記憶 體的電子機器。因此,在可印刷電子機器中也需要形成非 -5- 201131745 揮發性的記憶體電路。 本發明是有鑑於以上那樣的問題點而硏發者。若根據 本發明的幾個形態,則可提供一種能夠利用印刷技術來容 易製造的記憶格及記憶格的製造方法。 (用以解決課題的手段) (1 )本發明的記億格的形態之一係包含形成於基材 上的電晶體及電阻變化元件’ 前述電晶體係含: 閘極電極、源極電極及汲極電極; 通道部,其係含奈米碳管,與前述源極電極及前述汲 極電極接觸;及 絕緣部,介於前述閘極電極與前述通道部之間, 前述電阻變化元件係含: 第1電極及第2電極,其係間隔開形成,·及 電阻部,其係含奈米碳管,與前述第1電極及前述第2 電極接觸, 前述第1電極及前述第2電極的其中任一方係與前述源 極電極及HU述汲極電極的其中任一方共通。 若根據本發明,則可實現能夠利用印刷技術來容易製 造的記憶格。 (2)此記憶格可爲: 前述閘極電極係形成於前述基材上, 前述絕緣部係形成覆蓋前述閘極電極的至少一部分, -6- 201131745 前述源極電極及前述汲極電極係分別形成覆蓋前述絕 緣部的至少一部分, 前述通道部係形成覆蓋前述絕緣部的至少一部分, BU述桌1電極及目ij述第2電極的其中任一他方與前述電 阻部係形成於前述基材上。 (3 )此記憶格可爲: 前述源極電極、前述汲極電極及前述通道部係形成於 基材上 前述絕緣部係形成覆蓋前述通道部的至少一部分, 前述閘極電極係形成覆蓋前述絕緣部的至少一部分, 前述第1電極及前述第2電極的其中任一他方與前述電 阻部係形成於前述基材上。 (4 )此記憶格可爲: 前述通道部係含半導體性的奈米碳管。 藉此’構成記億格的電晶體的開關特性會提升。 (5 )此記憶格可爲: 前述電阻部係含導電性的奈米碳管。 藉此,構成記憶格的電阻變化元件的低電阻狀態與高 電阻狀態的電阻値的差會變大。因此,1與〇的讀出的差會 變明確,可實現能夠取得良好的記憶體特性之記憶格。 (6 )此記憶格可爲: 前述通道部係含3層以上的多壁奈米碳管的含有量比 單壁奈米碳管與雙壁奈米碳管的含有量的和更多。 3層以上的多壁奈米碳管通常是顯示半導體性。因此 201131745 ,構成記憶格的電晶體的開關特性會提升° (7 )此記憶格可爲: 前述電阻部係含單壁奈米碳管與雙壁奈米碳管的含有 量的和比3層以上的多壁奈米碳管的含有量更多。 單壁奈米碳管及雙壁奈米碳管因爲非常細’所以具有 隨電場等的力而容易彎曲,或隨熱的振動而彎曲容易變化 的性質。亦即,容易產生奈米碳管間的距離變化。因此’ 位於電阻變化元件的電極間的奈米碳管間容易從未被電性 連接的高電阻的狀態變化至藉庫倫力而被吸引電性連接的 低電阻狀態,或容易受熱的振動而從低電阻狀態變化至未 被電性連接的高電阻狀態。因此,可實現一種1與〇的讀出 的差會變明確,能取得良好的記憶體特性之記億格。 (8

[Prior Art] In recent years, a technique of manufacturing an electronic circuit using a printing technique (printable electronic device) has been developed. For example, a method of manufacturing a transistor using a printing technique is proposed in International Publication No. WO2007/078 8 60. On the other hand, even if the power is cut off, non-volatile materials such as flash memory (such as flash memory) are not developed. In the field of floating gates, it is used to store electrons in the field called floating gates, and to change the critical threshold voltage of the transistors according to the presence or absence of electrons in the floating gates, thereby recording the mode of 1 and 0. Further, various types of variable resistance elements such as MRAM (Magnetoresive Random Access Memory) or PCM (Phase Change Memory) have been proposed as ReRAM (Resistivity Change Random Access Memory). One of them is a non-volatile memory using a carbon nanotube as a variable resistance element in International Publication No. WO 2008/021 91 2 . SUMMARY OF THE INVENTION (Problems to be Solved by the Invention) An electronic device has an electronic device that uses a non-volatile memory in order to store various materials. Therefore, it is also necessary to form a non-volatile memory circuit in a printable electronic device. The present invention has been made in view of the above problems. According to several aspects of the present invention, it is possible to provide a method of manufacturing a memory cell and a memory cell which can be easily manufactured by using a printing technique. (Means for Solving the Problem) (1) One of the forms of the Geeuge of the present invention includes a transistor formed on a substrate and a variable resistance element. The electro-crystalline system includes: a gate electrode, a source electrode, and a drain electrode; a channel portion including a carbon nanotube, in contact with the source electrode and the drain electrode; and an insulating portion interposed between the gate electrode and the channel portion, wherein the resistance change element includes The first electrode and the second electrode are formed to be spaced apart from each other, and the resistor portion includes a carbon nanotube, and is in contact with the first electrode and the second electrode, and the first electrode and the second electrode are Either of these is common to either the source electrode and the HU electrode. According to the present invention, it is possible to realize a memory cell which can be easily manufactured by using a printing technique. (2) The memory cell may be: the gate electrode is formed on the substrate, and the insulating portion is formed to cover at least a portion of the gate electrode, -6-201131745, the source electrode and the drain electrode system respectively Forming at least a portion of the insulating portion, the channel portion is formed to cover at least a portion of the insulating portion, and any one of the electrode of the table 1 and the second electrode and the resistor portion are formed on the substrate . (3) The memory cell may be: the source electrode, the drain electrode, and the channel portion are formed on a substrate, the insulating portion is formed to cover at least a portion of the channel portion, and the gate electrode is formed to cover the insulation In at least a part of the portion, the other of the first electrode and the second electrode and the resistor portion are formed on the substrate. (4) The memory cell may be: The channel portion is a semiconducting carbon nanotube. By this, the switching characteristics of the transistors constituting the yoghurt will increase. (5) The memory cell may be: The resistor portion is a conductive carbon nanotube. Thereby, the difference between the low resistance state of the variable resistance element constituting the memory cell and the resistance 値 of the high resistance state becomes large. Therefore, the difference between the reading of 1 and 〇 is made clear, and a memory cell capable of achieving good memory characteristics can be realized. (6) The memory cell may be: The content of the multi-walled carbon nanotubes having three or more layers in the channel portion is more than the sum of the contents of the single-walled carbon nanotubes and the double-walled carbon nanotubes. Multi-walled carbon nanotubes of three or more layers generally exhibit semiconductivity. Therefore, in 201131745, the switching characteristics of the transistors constituting the memory cell are improved. (7) The memory cell can be: The resistance portion contains the content of the single-walled carbon nanotube and the double-walled carbon nanotube. The above multi-walled carbon nanotubes contain more. Since the single-walled carbon nanotubes and the double-walled carbon nanotubes are very thin, they have a property of being easily bent in accordance with a force such as an electric field, or being bent easily with vibration of heat. That is, it is easy to produce a change in the distance between the carbon nanotubes. Therefore, the carbon nanotubes located between the electrodes of the variable resistance element are easily changed from a state of high resistance that is not electrically connected to a state of low resistance that is attracted to the coulomb force and is electrically connected, or is susceptible to heat. The low resistance state changes to a high resistance state that is not electrically connected. Therefore, it is possible to realize that the difference between the reading of 1 and 〇 is clear, and the memory of good memory characteristics can be obtained.

According to the present invention, non-volatile cells can be easily produced by coating techniques or printing techniques. Further, the memory cell can be produced at a temperature (e.g., about 100 to 200 ° C) to the extent that the solvent (or dispersion medium) of the ink is vaporized. (9) One aspect of the method of manufacturing the Geeigge of the present invention includes a source electrode forming process in which a conductive ink is applied onto a substrate to form a source electrode; and a gate electrode formation process is performed on a conductive ink is applied to the substrate to be spaced apart from the source electrode to form a drain electrode; and the electrode is formed by applying a conductive ink to the substrate to be spaced apart from the source electrode and the drain electrode.

According to the present invention, a non-volatile memory cell can be easily fabricated by a coating technique or a printing technique. Further, the memory cell can be produced at a temperature (e.g., about 100 to 200 ° C) to the extent that the solvent (or dispersion medium) of the ink is vaporized. (1) One aspect of the method for producing a memory cell of the present invention includes a gate electrode formation process in which a conductive ink is applied onto a substrate to form a gate electrode; and an electrode formation process is performed on the base a conductive ink is applied to the material to form an electrode spaced apart from the gate electrode; and an insulating portion forming process is performed by applying an insulating ink so as to cover at least a part of the gate electrode to form an insulating portion; a forming process for forming a resistor portion by coating a carbon nanotube ink so as to be in contact with the electrode; and a source electrode forming process for applying a conductive ink so as to cover at least a part of the insulating portion Forming a source electrode insulated from the gate electrode; -10-201131745 A gate electrode forming process for applying a conductive ink so as to be spaced apart from the source electrode so as to cover at least a portion of the insulating portion a drain electrode insulated from the gate electrode; a channel portion forming process capable of covering at least a portion of the insulating portion, and The carbon nanotube ink is applied to the source electrode and the drain electrode to form a channel portion insulated from the gate electrode, and the source electrode forming process and the gate electrode forming process are both The conductive ink is applied so as to cover at least a part of the resistor portion to form one of the source electrode and the drain electrode. According to the present invention, a non-volatile memory cell can be easily fabricated by a coating technique or a printing technique. Further, the memory cell can be produced at a temperature (e.g., about 100 to 2 ° C) at which the solvent (or dispersion medium) of the ink is vaporized. (1) The manufacturing method of the memory cell may be performed by the same process of forming the channel portion forming process and the resistor portion forming process. This makes it easier to create memory cells. (1 2) The manufacturing method of the yoghurt may be: applying the carbon nanotube ink containing a semiconducting carbon nanotube in the channel forming process. Thereby, the switching characteristics of the transistors constituting the memory cell are improved. (1 3) The manufacturing method of the yoghurt may be: applying the carbon nanotube ink containing the conductive carbon nanotube -11 - 201131745 in the formation of the resistor portion. Thereby, the difference between the low resistance state of the variable resistance element composed of one of the source electrode and the drain electrode, the first electrode and the resistor portion, and the resistance 値 of the high resistance state becomes large. Therefore, it is possible to create a memory cell in which the difference between the reading of 1 and 〇 is clear, and a good memory characteristic can be obtained. (I4) The method for manufacturing the memory cell may be: in the channel forming process, the content of the multi-walled carbon nanotubes containing three or more layers is compared with the single-walled carbon nanotubes and the double-walled carbon nanotubes. The content of the above and more of the aforementioned carbon nanotube ink. Multi-walled carbon nanotubes of three or more layers generally exhibit semiconductivity. Therefore, the switching characteristics of the transistors constituting the memory cell are improved. (1) The manufacturing method of the memory cell may be: in the formation of the resistor portion, the coating of the content of the single-walled carbon nanotube and the double-walled carbon nanotube is more than three layers of the multi-walled nai The carbon nanotubes contain more of the aforementioned carbon nanotube ink. Since the single-walled carbon nanotubes and the double-walled carbon nanotubes are very thin, they have a property of being easily bent by a force such as an electric field, or being bent easily with vibration of heat. That is, it is easy to produce a change in the distance between the carbon nanotubes. Therefore, the carbon nanotubes located between the electrodes of the variable resistance element are easily changed from a state of high resistance that is not electrically connected to a state of low resistance that is attracted to the coulomb force and is electrically connected, or is susceptible to heat. The low resistance state changes to a high resistance state that is not electrically connected. Therefore, it is possible to make a difference between the readout of 1 and 0, and to obtain a memory of good memory characteristics. -12-201131745 [Embodiment] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.
