Title: Manufacturing method of semiconductor device
Inventor: MORITA MASANORI
IPC: G01R31/26
Filed: 2001-12-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a technology capable of preventing deformation of a lead of a semiconductor device in a characteristic test, and facilitating the lead adjustment work when testing the semiconductor device dismounted from a substrate.  <P>SOLUTION: In this manufacturing method of the semiconductor device wherein the semiconductor device formed by arranging a plurality of leads in a row on the periphery of a sealed body is stored in a socket and a test is performed by bringing the leads into contact with contact pins of the socket conductively, the socket having the contact pins provided thereon to be brought into contact with the leads on positions near the sealed body is used. Since the contact pins are brought into contact with the positions near the sealed body by this constitution, the leads have higher intensity compared with the case of a tip part, to thereby prevent deformation thereof. In addition, since a peripheral part of the sealed body is not fixed on the substrate, a position shift caused by deformation or adhesion of solder is not generated to thereby facilitate the lead adjustment work, when testing the semiconductor device dismounted from the substrate.  <P>COPYRIGHT: (C)2003,JPO

Abstract: (57)【要約】
本発明は、新しいプラズマディスプレイパネル（ＰＤＰ）制御に関する。従来のＰＤＰ制御の原理は、サブフィールドアドレッシングとプライミングの組合せに基づいている。プライミング期間内で、パネルの全てのプラズマセルは、強い電圧パルスによって予備励起される。このセルの処理は、達成可能なコントラストを低下させるので、画質の面で欠点となる僅かなバックグラウンド輝度を生じさせる。本発明によれば、このハードなプライミング期間の代わりに、自己プライミング・サブフィールド（ＳＰＳＦ）及びリフレッシュ・サブフィールドを使用することが提案される。この考え方を導入することにより、黒であるべきセルは黒の状態を維持する。セルフプライミング・サブフィールド（ＳＰＳＦ）は、プライミングの必要性を削減若しくは除去するので、暗い領域を更に暗くさせ、一方、リフレッシュ・サブフィールド（ＲＳＦ）は、高速にアドレス指定され得る。実際、フレーム期間内のリフレッシュ・サブフィールド（ＲＳＦ）の数は、セルフプライミング・サブフィールド（ＳＰＳＦ）の数よりも多い。したがって、総アドレッシング時間は、この新しい技術によって削減され得る。高速アドレッシングは、維持パルスのためにより多くの時間を残すので、明るい領域をより明るくさせることが可能である。これは、特に、７５Ｈｚのマルチメディアソースに接続されたＰＤＰモニターの場合に顕著な効果がある。
