A new remover chemistry based on a choline compound, such as choline hydroxide, is provided in order to address problems related to removal of residues, modified photoresists, photoresists, and polymers such as organic anti-reflective coatings and gap-fill and sacrificial polymers from surfaces involved in dual damascene structures without damaging the dielectrics and substrates involved therein. An etch stop inorganic layer at the bottom of a dual damascene structure may or may not be used to cover the underlying interconnect of copper. If not used, a process step of removing that protective layer can be avoided through a timed etch of the via in trench-first dual damascene processes.

A system is disclosed for creating a hole in a body vessel or hollow organ. Such holes are useful in surgically preparing the hollow organ or body vessel for connection with another hollow organ, body vessel or prosthetic conduit. For example, an assist device is generally connected to the left ventricle through a ventriculotomy created at the apex of the left ventricle. This ventriculotomy is most easily created with a punch or trephine. Control over such a procedure must be precise so as not to damage the ventricular wall or intracardiac structures such as papillary muscles, chordae tendinae, etc. The punch of the current invention allows for precise location and alignment of the cutting segment. The punch of the current invention also allows for precise advance of the cutting blade and a very clean cut of the tissue. Such clean cuts improve the healing when the hole in the body vessel or hollow organ is closed or attached to a connection, either prosthetic or natural.
