Description
本出願は、参照により本明細書に組み込む2007年9月12日出願の米国仮特許出願第60/971,859号、および2007年9月20日出願の米国仮特許出願第60/974,045号の優先権の利益を主張する。
本明細書に記載の工程によって生成される装置は、ナノ構造体が担体内部に埋め込まれた担体を備え、このナノ構造体は、特定の形状および機能を有するように成長させた。ナノ構造体は、おおよそ互いに平行であり、また基板に対して垂直になるように方向付けられる。ナノ構造体は、概ね所望の長さまたは高さを有する。
この実施例は、2つの面/層(第1のダイまたはチップの接触面/層と、第2のダイまたはチップの、第1のものが装着される接触層/面との間など)を接続する方法を提示する。この接続は、1mmから2nmの範囲のいずれかのピッチで、通常は電気的/熱的接触要素がナノ構造体に基づく20nmまでのピッチで、接合および電気的/熱的接触させることにより行われる。
垂直に並べられたナノ構造体(NS)(互いに平行で、両担体面に対して垂直であり、実施例1に記載のステップで用意されたものなど)を含む担体(可撓性、ポリイミド、または固い材料をベースとすることができる)が、ダイの表面と接触面の間に置かれる。例として図2および図4を参照されたい。
この実施例は、電子回路のI/O点上にナノ構造体のマトリクスを成長させることによってどのようにウェハレベルバンプを実現し、それによってダイの電子アセンブリを生成するかを示す。この方法は、1cmから2nmの範囲の任意のピッチで、通常は電気的/熱的接触要素がナノ構造体に基づく1μmまでの範囲のピッチで、接合し、かつ電気的および/または熱的に接触させることにより、2つの面/層(ダイまたはチップの接触面/層、および第1層が接続されるダイまたはチップの接触面/層)を接続する方法とすることもできる。
