Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はボンディング電極の構造に関する。
〔従来の技術〕
従来のボンディング電極構造は、電子材料、１９８５年
、５月号、Ｐ１０７〜Ｐ１１２．早用征男：ハイデンシ
ティボンデイングへのアプローチ　などで示される様に
、被ボンデイング部分が平担となっている。
〔発明が解決しようとする問題点〕
ボンデイング工程に於いて、その高速化）；進む中で、
ボンディング時間短縮に判う、ボンダビリティ低下が問
題となりている。
〔問題点を解決する為の手段〕
本発明はこの様な問題点を解決するもので、その目的と
するところは、ボンディング部分を凹凸構造とすること
で、ボンダビリティ向上を提供することにある。
〔実施例〕
以下、本発明について実施例に基づき詳細に説明する。
一実施例は、半導体に於けるポンディングパッド電極で
あり、例えば第１〜３図に示す様に、電極形成時のフォ
トエツチング工程で、−ボンディング部分を選択的に除
去するか、又は例えば第４図の様に電極形成前にパッド
下部に８１０！ガラス等を部分的に設けることにより凹
凸とした構造である。
第１〜３図にポンディングパッドを選択的にエツチング
した場合の電極構造例、第４図にパッド下に８１０．ガ
ラスを部券“的に設けた場合の電極構造例、第５図に従
来の電極構造を示す。
〔発明の効果〕
以上述べた様に、ポンディング部分を凹凸構造としたの
で、ボンディング相互間の接触面積を増加させることが
可能であり、従来の方式で問題となっている低ボンダビ
リティを向上させる効果を有する。
【図面の簡単な説明】
第１図はポンディングパッドを選択的にエツチングした
電極構造図。 第２図は、第１図中Ｘ−Ｘ’の電極断面構造図第３図は
電極の二層形成プロセスにより一層目を選択エツチング
した電極断面構造図。 第４図は、ポンディングパッド下にＳ　ｉ　Ｏ，ガラス
等を部分的に設けた電極断面構造図。 第５図は従来の電極断面構造図。 α・・・・・・ムＬのポンディングパッド電極ｂ・・・
