Dual damascene processing for semiconductor chip interconnects
Alfred Grill,John P. Hummel,Christopher V. Jahnes,Vishnubhai Vitthalbhai Patel,Katherine L. Saenger +4 more
TL;DR: In this paper, a dual-pattern hard mask is proposed to protect organic interlevel and intralevel dielectrics from potential damage induced by photoresist stripping steps during lithographic rework.
Patent
Production of electroless Co(P) with designed coercivity
TL;DR: In this paper, a method and solution for the electroless deposition of Co(P) with a designed coercivity via the programmed addition of supporting electrolytes comprising such sulfur containing compounds as sulfamic acid, potassium sulfate or sodium sulfate to a solution having a source of cobalt ions, an ion buffering compound to stabilize the pH of the solution, and sufficient hydroxide anions to obtain a pH between about 7 and 9.
