Title: Constitutional body and method of forming enlarged head of plug used for eliminating enclosure requirement
Inventor: SMITH GREGORY C
IPC: H01L21/302
Filed: 2007-03-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a technique for forming a contact opening which is hardly corroded when an interconnecting layer is formed.  <P>SOLUTION: A contact opening is formed penetrating through an insulating layer 34 so that it has a straight sidewall part 42 and a bowl-shaped sidewall part 40. The bowl-shaped sidewall part 40 is located close to the top part of the insulating layer 34 to make the top part of the contact opening wider in diameter than its base. A conductive material 46 is formed inside the contact opening, electrically coming into contact with a lower conductive layer 32. The conductive material 46 forms a plug 47 having an enlarged head 52. The enlarged head 52 protects a barrier layer 45 located inside the contact opening against anisotropic etching which is carried out later. Therefore, when an electric interconnecting layer 48 of aluminum or the like is formed over the contact plug 47, the contact plug serves as an etching stopper to protect the barrier layer inside the contact opening against etching.  <P>COPYRIGHT: (C)2007,JPO&INPIT
