Definitions
- the present invention relates to a negative photosensitive resin composition and a method for producing a polyimide and a cured relief pattern using the same.
- polyimide resin, polybenzoxazole resin, phenol resin, etc. which have excellent heat resistance, electrical properties and mechanical properties, are used for insulating materials for electronic components and passivation films, surface protective films, interlayer insulating films, etc. for semiconductor devices. Used.
- those provided in the form of a photosensitive resin composition easily form a heat-resistant relief pattern film by thermal imidization treatment by application, exposure, development, and curing of the composition. be able to.
- Such a photosensitive resin composition has a feature that the process can be significantly shortened as compared with a conventional non-photosensitive material.
- a semiconductor device (hereinafter, also referred to as an “element”) is mounted on a printed circuit board by various methods according to purposes.
- a conventional device is generally manufactured by a wire bonding method for connecting from an external terminal (pad) of the device to a lead frame with a thin wire.
- the difference in the wiring length of each terminal in mounting has influenced the operation of the element. For this reason, it is necessary to accurately control the length of the mounting wiring when mounting an element for high-end use, and it has become difficult to satisfy the requirement by wire bonding.
- flip-chip mounting has been proposed in which a redistribution layer is formed on the surface of a semiconductor chip, bumps (electrodes) are formed thereon, and then the chip is turned over and mounted directly on a printed circuit board (for example, see Patent Reference 1).
- the flip chip mounting since the wiring distance can be accurately controlled, the flip chip mounting is adopted for a high-end device for handling a high-speed signal or for a mobile phone or the like because of a small mounting size, and the demand is rapidly increasing.
- a metal wiring layer forming step is performed after the pattern of the resin layer is formed.
- the metal wiring layer is usually made by plasma etching the surface of the resin layer to roughen the surface, then forming a metal layer to be a seed layer for plating by sputtering at a thickness of 1 ⁇ m or less, and using the metal layer as an electrode for electrolytic plating. Is formed.
- titanium (Ti) is used as a metal for the seed layer
- copper (Cu) is used as a metal for the rewiring layer formed by electrolytic plating.
- a reliability test for example, storage in air at a high temperature of 125 ° C. or more for 100 hours or more; a high-temperature storage test; High-temperature operation test for confirming operation under storage over a long period of time; a temperature cycle in which a low-temperature state of about ⁇ 65 ° C. to ⁇ 40 ° C. and a high-temperature state of about 125 ° C. to 150 ° C. cycle in air.
- Test High-temperature, high-humidity storage test; storage at a temperature of 85 ° C.
- the metal rewiring layer is required to have chemical resistance, and the demand for miniaturization is increasing. For this reason, in particular, a photosensitive resin composition used for forming a redistribution layer of a semiconductor is required to suppress generation of voids and exhibit high chemical resistance and high resolution.
- the present invention has been devised in view of such a conventional situation, and has high chemical resistance and resolution, and comes into contact with a resin layer of a Cu layer after a high temperature storage test.
- An object is to provide a negative photosensitive resin composition (hereinafter, also simply referred to as “photosensitive resin composition” in the present specification) that can suppress generation of voids at an interface. It is another object to provide a method for forming a cured relief pattern using the negative photosensitive resin composition of the present invention.
- fan-out type semiconductor packages have attracted attention.
- a chip sealing body larger than the chip size of the semiconductor chip is formed by covering the semiconductor chip with a sealing material. Further, a rewiring layer extending to the region of the semiconductor chip and the sealing material is formed. The rewiring layer is formed with a small thickness. Further, since the rewiring layer can be formed up to the region of the sealing material, the number of external connection terminals can be increased.
- the fan-out type semiconductor package requires a further lowering of the curing temperature, and as a result, the adhesiveness with a sealing material such as a mold resin is reduced, so that further improvement is required.

6インチシリコンウェハー(フジミ電子工業株式会社製、厚み625±25μm)上に、スパッタ装置(L-440S-FHL型、キヤノンアネルバ社製)を用いて200nm厚のTi、400nm厚のCuをこの順にスパッタした。続いて、このウェハー上に、後述の方法により調製したネガ型感光性樹脂組成物をコーターデベロッパー(D-Spin60A型、SOKUDO社製)を用いて回転塗布し、110℃で180秒間ホットプレートにてプリベークを行い、約7μm厚の塗膜を形成した。この塗膜に、テストパターン付マスクを用いて、プリズマGHI(ウルトラテック社製)により500mJ/cm2のエネルギーを照射した。次いで、この塗膜を、現像液としてシクロペンタノンを用いてコーターデベロッパー(D-Spin60A型、SOKUDO社製)でスプレー現像し、プロピレングリコールメチルエーテルアセテートで、リンスすることにより、Cu上のレリーフパターンを得た。Cu上に該レリーフパターンを形成したウェハーを、昇温プログラム式キュア炉(VF-2000型、光洋リンドバーグ社製)を用いて、窒素雰囲気下、表1に記載の硬化温度において2時間加熱処理することにより、Cu上に約4~5μm厚の樹脂から成る硬化レリーフパターンを得た。
上記の方法で得た硬化レリーフパターンを光学顕微鏡下で観察し、最少開口パターンのサイズを求めた。このとき、得られたパターンの開口部の面積が、対応するパターンマスク開口面積の1/2以上であれば解像されたものとみなし、解像された開口部のうち最小面積を有するものに対応するマスク開口辺の長さを解像度とした。解像度が10μm未満のものを「優」、10μm以上14μm未満のものを「良」、14μm以上18μm未満のものを「可」、18μm以上のものを「不可」とした。
Cu上に該硬化レリーフパターンを形成したウェハーを、昇温プログラム式キュア炉(VF-2000型、光洋リンドバーグ社製)を用いて、空気中、150℃で168時間加熱した。続いて、プラズマ表面処理装置(EXAM型、神港精機社製)を用いて、Cu上の樹脂層を全てプラズマエッチングにより除去した。プラズマエッチング条件は下記の通りである。
出力:133W
ガス種・流量:O2:40mL/分 + CF4:1mL/分
ガス圧:50Pa
モード:ハードモード
エッチング時間:1800秒

Cu上に形成した該硬化レリーフパターンを、レジスト剥離液{ATMI社製、製品名ST-44、主成分は2-(2-アミノエトキシ)エタノール、1-シクロヘキシル-2-ピロリドン}を50℃に加熱したものに5分間浸漬し、流水で1分間洗浄し、風乾した。その後、膜表面を光学顕微鏡で目視観察し、クラック等の薬液によるダメージの有無や、薬液処理後の膜厚の変化率をもって耐薬品性を評価した。評価基準として、クラック等が発生せず、膜厚変化率が薬品浸漬前の膜厚を基準として10%以下のものを「優」、10%超~15%以下のものを「良」、15%超~20%以下のものを「可」とし、クラックが発生したもの、または膜厚変化率が20%を超えるものを「不可」とした。
エポキシ系封止材として、長瀬ケムテックス社製のR4000シリーズを用意した。アルミスパッタしたシリコーンウエハー上に、封止材を厚みが約150ミクロンになるようにスピンコートし、130℃で熱硬化させてエポキシ系封止材を硬化させた。上記エポキシ系硬化膜上に、各実施例、及び各比較例で作製した感光性樹脂組成物を最終膜厚が10ミクロンになるように塗布した。塗布した感光性樹脂組成物を、アライナ(PLA-501F、キャノン社製)を用いて露光量600mJ/cm2のghi線で全面を露光した。その後、180℃、2時間にて熱硬化させて、厚み10ミクロンの1層目の硬化膜を作成した。
