Description
(適用なし)
液晶ポリマーの如き種々のプラスチックが、消費者用製品、医療用機器および電子集積回路用のパッケージを含む、広範の製造製品に使用されている。多くの例において、プラスチックは1またはそれ以上の製品の工程中または製品の使用中のような製造後において、加熱される。例えば、多くの製品は射出成形によって製造され、それはプラスチックの軟化のために加熱し、その軟化されたプラスチックを金型に射出することを含む。そのプラスチックは金型の形状を呈し、その後の製造工程、およびできた製品の有用な寿命の間ずっとその形状を保持する。ある製造工程及び製品は、従来のプラスチックの融点よりも高い融点を有するプラスチックの使用を介して改良される。他の製造工程及び製品は、プラスチックがある形状に成形された後で、プラスチックのオリジナルの融点より高い温度を必要とする引き続く工程の前に、その融点が引き上げられたプラスチックを使用することによって利益がもたらされる。
結果的に、既存のプラスチックは、既存の液晶ポリマーを含めて集積回路には使用できない。
その代わりに、メーカーは一般的にセラミック金属を使用する。しかし乍、セラミックスは他の集積回路の部品にろう付けされねばならない。ろう付けは、約800℃の高温プロセスで、集積回路において平坦性欠落(out−of−flatness)の如き機械的問題を起こす。さらに、セラミックスが関与する製造工程は高価である。
本発明のこれら及びその他の特徴、利点、態様および形態は、以下の発明の詳細な記載に基づいて当業者により明らかになるであろう。
従来の重合工程においては、ポリマーはモノマーから一般的には液体の形体で作られ、そしてポリマー鎖が成長した後に、生じた材料は一般には冷却されて固体状である。
例示のオリジナル材料は、「芳香族ポリエステル」または液晶ポリマーとして知られる材料の仲間の材料を含む。
