Further, a second laminated body is formed in the same manner as in Example 1, and a third laminated body is formed in the same manner as in Example 1 using the first laminated body and the second laminated body. A curing step, two lamination steps, and an exposure step were performed.
- the protective sheet 11 was peeled off in the same manner as in Example 1, and the third laminate was immersed in an aqueous sodium carbonate solution, but the resist layer 12 did not dissolve and could not be patterned. . It is considered that plasma by the sputtering method sensitized the resist layer 12 and the resist layer 12 was cured. According to this comparative example, it was found that it is not suitable to use a method in which the resist layer 12 is exposed to form the metal layer 13.

Description
エポキシ系樹脂、アクリル系樹脂等の光硬化性樹脂、エポキシ系樹脂、アクリル系樹脂等の熱硬化性樹脂、又はエチレン酢酸ビニル(EVA)等の熱可塑性樹脂を用いることができる。これらの樹脂の他に、2液混合型や水分硬化型の樹脂を用いてもよい。樹脂層23の形成方法には一般的な成膜方法を用いる。なお、樹脂層23は後にトランジスタのゲート絶縁膜として用いられる。
本実施例では、第1の積層体における保護シート11及びレジスト層12として、DFR(日立化成製:RD-1225)を用いる。本DFRは、保護シート11上に25μmの感光性樹脂が被覆されている。次に、第1の積層体における金属層形成工程として、DFRに対してイオンビームスパッタを用いてCu粒子を付着させ、金属膜である金属層13を成膜した。これにより、高い密着性と平坦性とを有する金属層13が得られた。
第2の積層体の金属層形成工程において、基板21にPETを用い、金属層22にCuを使用して金属層22を形成した。その後、接着兼絶縁層形成工程において、樹脂層23に用いる絶縁体として樹脂に代わって200nmの酸化アルミニウム薄膜を準備し、金属層22に対して積層して第2の積層体を形成した。その後、第1の積層体が有する半導体層14と酸化アルミニウム薄膜とを接触させて第3の積層体を形成したが、酸化アルミニウムは無機材料であるため、上述のラミネート1工程と硬化工程は行わなかった。
実施例1と同様に、保護シート11及びレジスト層12としてDFRを用いた。次に、第1の積層体における金属層形成工程として、DFRに対してスパッタ法を用いてCuの金属層13を成膜した。その際、プラズマによるダメージがレジスト層12に影響を与えないよう、ターゲットであるCuとDFRとの距離を充分に離してスパッタを行った。
