Definitions
- the present invention relates to a resist underlayer film forming composition for lithography effective at the time of processing a semiconductor substrate, a resist pattern forming method using the resist underlayer film forming composition, and a method for manufacturing a semiconductor device.
- a thin film of a photoresist composition is formed on a substrate to be processed such as a silicon wafer, and irradiated with actinic rays such as ultraviolet rays through a mask pattern on which a semiconductor device pattern is drawn, and developed.
- actinic rays such as ultraviolet rays
- This is a processing method for etching a substrate to be processed such as a silicon wafer using the obtained photoresist pattern as a protective film.
- EUV lithography and EB lithography generally do not require a specific anti-reflection film because they do not cause diffuse reflection or standing wave from the substrate, but an auxiliary film for the purpose of improving the resolution and adhesion of the resist pattern As such, the resist underlayer film has begun to be widely studied.
- the resist pattern becomes finer, it is indispensable to make the resist thinner. This is because the resolution is reduced due to miniaturization and the formed resist pattern is likely to collapse. Therefore, it becomes difficult to maintain the resist pattern film thickness necessary for substrate processing, and not only the resist pattern but also the resist underlayer film formed between the resist and the semiconductor substrate to be processed is used as a mask during substrate processing. It became necessary to have a function.
- a lithography process is used in which at least two resist underlayer films are formed and the resist underlayer film is used as an etching mask.
- the resist pattern is transferred to the lower layer film by an etching process
- the substrate processing is performed using the lower layer film as a mask
- the resist pattern is transferred to the lower layer film by an etching process, and further transferred to the lower layer film.
- a process of repeating the process of transferring the formed pattern to the lower layer film using a different etching gas and finally processing the substrate is used.
- a resist underlayer film for a lithography process is required to have high etching resistance against an etching gas (for example, fluorocarbon) in a dry etching process.
- Examples of the polymer for the resist underlayer film include the following.
- a resist underlayer film forming composition using polyvinyl carbazole is exemplified (see Patent Document 1, Patent Document 2, and Patent Document 3).
- a resist underlayer film forming composition using a fluorenephenol novolak resin is disclosed (for example, see Patent Document 4).
- a resist underlayer film forming composition using a fluorene naphthol novolak resin is disclosed (see, for example, Patent Document 5).
- a resist underlayer film forming composition containing a resin having fluorenephenol and arylalkylene as repeating units is disclosed (see, for example, Patent Document 6 and Patent Document 7).
- a resist underlayer film forming composition using carbazole novolak is disclosed (for example, see Patent Document 8).
- a resist underlayer film forming composition using a polynuclear phenol novolak is disclosed (for example, Patent Document 9).

- the resist underlayer film that serves as an etching mask requires a resist underlayer film having high pattern bending resistance that can suppress the occurrence of pattern bending even in a fine pattern.
- the resist underlayer film forming composition is formed using a spin coater in the same manner as the resist composition.
- a polymer resin, a crosslinking agent, a crosslinking catalyst, etc. which are the main components of the resist underlayer film forming composition, are used in an appropriate solvent. It needs to be dissolved.
- solvents include propylene glycol monomethyl ether (PGME), propylene glycol monomethyl ether acetate (PGMEA), cyclohexanone, and the like used in the resist forming composition, and the resist underlayer film forming composition includes these. It must have good solubility in the solvent.
- a sublimation component (sublimation product) derived from a low molecular compound such as the polymer resin, a crosslinking agent, or a crosslinking catalyst is generated.
- a sublimation product derived from a low molecular compound such as the polymer resin, a crosslinking agent, or a crosslinking catalyst.

- the QCM sensor measures a small amount of mass change by utilizing the property that the frequency of the crystal unit changes (decreases) according to its mass when a sublimate adheres to the surface (electrode: AlSi) of the crystal unit. Is possible.
- the obtained frequency change was converted from the eigenvalue of the crystal resonator used for measurement into mass units (grams), and the amount of sublimation per wafer coated with the resist underlayer film was quantified.
- Sublimate amount ratio obtained by dividing the sublimate amounts of Examples 1 to 12, Comparative Example 1 and Comparative Example 2 determined from the apparatus by the sublimate amount of Comparative Example 1 (when the sublimate amount of Comparative Example 1 was normalized to 1) Table 2 shows the relative ratio).
- the amount of sublimate generated from the resist underlayer film forming compositions of Examples 1 to 12 is smaller than the amount of sublimate generated from the resist underlayer film forming compositions of Comparative Examples 1 and 2. That is, the resist underlayer film forming compositions of Examples 1 to 12 can effectively suppress the amount of sublimate generated compared to the resist underlayer film forming compositions of Comparative Examples 1 and 2.
- each resist underlayer film forming composition prepared in Examples 1 to 12, Comparative Example 1 and Comparative Example 2 was applied by a spin coater onto a silicon wafer with a silicon oxide film having a diameter of 8 inches and a thickness of 300 nm. Then, it was baked on a hot plate at 400 ° C. for 2 minutes to form a resist underlayer film having a film thickness of 200 nm.
- a silicon hard mask forming composition (a composition obtained by dissolving polyorganosiloxane in an organic solvent) was applied on the resist underlayer film, and baked at 240 ° C. for 1 minute to form a silicon hard mask layer having a film thickness of 45 nm. .
- a resist solution for ArF excimer laser was applied and baked at 100 ° C. for 1 minute to form a resist layer having a thickness of 120 nm.
- Exposure was performed with an ArF excimer laser (wavelength: 193 nm) using a mask, followed by baking at 105 ° C. for 1 minute and heating (PEB), followed by alkali development to obtain a resist pattern.
- PEB heating
- dry etching was performed with a fluorine-based gas (component is CF 4 ), and the resist pattern was transferred to a hard mask.
- dry etching was performed with an oxygen-based gas (component is O 2 / CO 2 ), and the formed hard mask pattern was transferred to the resist underlayer film.
- the resistance to pattern bending of the resist underlayer film forming compositions in Examples 1 to 12, Comparative Example 1 and Comparative Example 2 can be improved. evaluated. That is, by measuring the pattern width (processing limit line width) after the formation of the resist pattern immediately before the start of pattern bending, the pattern bending resistance can be evaluated. Table 3 shows the measured value of the processing limit line width of the resist pattern formation word.
- the resist underlayer film forming composition can effectively suppress the bending of the pattern as the processing limit line width is smaller, fine substrate processing becomes possible.
- the resist underlayer film forming compositions of Examples 1 to 12 have a smaller processing limit line width at which pattern bending occurs than Comparative Examples 1 and 2, and therefore, finer substrate processing is possible. It becomes. That is, it was shown that the resist underlayer film forming compositions of Examples 1 to 12 have high pattern bending resistance.
- the resist underlayer film material used in the lithography process using the multilayer film of the present invention not only has high dry etching resistance and antireflection film function, but also has excellent spin coating properties because of its high solubility in resist solvents.
- there are few sublimation components generated in the baking process of the resist underlayer film forming composition and finer substrate processing is achieved by suppressing the occurrence of wiggling (irregular pattern bending) of the resist underlayer film during the dry etching process.

<比較例2>
合成例23で得られたノボラック樹脂を、合成例24で得られたノボラック樹脂に変えた以外は比較例1と同様に行った。
実施例1乃至実施例12、比較例1及び比較例2で調製した各レジスト下層膜形成組成物に用いられる成分(樹脂)を、代表的なレジスト溶剤であるプロピレングリコールモノメチルエーテル(PGME)、プロピレングリコールモノメチルエーテルアセテート(PGMEA)、シクロヘキサノン(CYH)に1質量部(レジスト下層膜形成組成物の固形分)/10質量部(レジスト溶剤)の割合となるように混合し、混合液中からノボラック樹脂に由来するレジスト下層膜形成組成物の成分の析出が確認できるか否かを観察した。析出が観察されなかった場合は、レジスト下層膜形成組成物の成分の溶解性を「良好」とし、析出によって沈殿物の生成や混合液に濁りが観察された場合は、レジスト下層膜形成組成物の成分の溶解性を「不良」とした。このレジスト下層膜形成組成物の成分の溶解性試験の結果を表1に示す。
なお、上記結果は実施例1乃至実施例12、比較例1乃至比較例2に用いられている成分(樹脂)が、レジスト下層膜形成組成物として基板に被覆し乾燥する前の成分の溶剤への溶解性を示す試験結果であって、当該レジスト下層膜形成組成物を基板に被覆し乾燥後は、レジスト溶剤への再溶解性はない。
昇華物量の測定は国際公開第2007/111147号パンフレットに記載されている昇華物量測定装置を用いて実施した。まず、直径4インチのシリコンウェハーに実施例1乃至実施例12、比較例1及び比較例2で調製したレジスト下層膜形成組成物をスピンコーターにて、膜厚90nmとなるように塗布した。レジスト下層膜が塗布されたウェハーをホットプレートが一体化した前記昇華物量測定装置にセットし、240℃で60秒間ベークした際に発生する昇華物をQCM(Quartz Crystal Microbalance)センサー、すなわち電極が形成された水晶振動子に捕集した。QCMセンサーは、水晶振動子の表面(電極:AlSi)に昇華物が付着するとその質量に応じて水晶振動子の周波数が変化する(下がる)性質を利用して、微量の質量変化を測定することが可能である。得られた周波数変化は測定に使用した水晶振動子の固有値から質量単位(グラム)に換算し、レジスト下層膜が塗布されたウェハー1枚当たりの昇華物量を定量した。当該装置から定量した実施例1乃至実施例12、比較例1及び比較例2の昇華物量を比較例1の昇華物量で除した昇華物量比(比較例1の昇華物量を1と規格化した際の相対比)を表2に示す。
まず、直径8インチの膜厚300nmの酸化ケイ素被膜付きシリコンウエハー上に実施例1乃至実施例12、比較例1及び比較例2で調製した各レジスト下層膜形成組成物をスピンコーターにて塗布し、ホットプレート上で400℃2分間焼成して、膜厚200nmとなるようにレジスト下層膜を形成した。次に、レジスト下層膜上にシリコンハードマスク形成組成物(ポリオルガノシロキサンを有機溶剤に溶解した組成物)を塗布し、240℃で1分間焼成して膜厚45nmのシリコンハードマスク層を形成した。さらに、ArFエキシマレーザー用のレジスト溶液を塗布し、100℃で1分間焼成して膜厚120nmのレジスト層を形成した。マスクを用いてArFエキシマレーザー(波長193nm)で露光し、露光後、105℃で1分間焼成して加熱(PEB)を行った後、アルカリ現像してレジストパターンを得た。その後、フッ素系ガス(成分はCF4)でドライエッチングを行い、レジストパターンをハードマスクに転写した。さらに、酸素系ガス(成分はO2/CO2)でドライエッチングを行い、形成されたハードマスクのパターンを本レジスト下層膜に転写した。その後、フッ素系ガス(成分はC4F6/C4F8/O2/Ar)でドライエッチングを行い、本レジスト下層膜のパターンを酸化ケイ素被膜に転写した。尚、レジストパターン及び段階的に転写されたパターン形状は測長走査型電子顕微鏡にて観察した。このような段階的なエッチング工程におけるレジストパターンの転写では、酸化ケイ素被膜加工時にパターン幅が縮小するにしたがいウイグリング(wiggling)と呼ばれる不規則なパターンの曲がりが発生し、忠実なパターン転写に基づく基板加工が困難となる。そこで、このような酸化ケイ素被膜のパターン曲がりの発生を電子顕微鏡にて観察することにより、実施例1乃至実施例12、比較例1及び比較例2におけるレジスト下層膜形成組成物のパターン曲がり耐性を評価した。すなわち、パターンの曲がりが発生し始める直前のレジストパターン形成後のパターン幅(加工限界線幅)を測定することで、パターンの曲がり耐性を評価することができる。表3にレジストパターン形成語の加工限界線幅の測定値を示す。尚、この加工限界線幅が小さい程、レジスト下層膜形成組成物はパターンの曲がりを効果的に抑制することができるため、微細な基板加工が可能となる。
