Abstract:
A technique relates to a magnetic device. A stack is formed including a magnetic tunnel junction (MTJ), the MTJ including a reference magnetic layer and a free magnetic layer sandwiching a tunnel barrier layer. A protective film is formed on a bottom portion of the MTJ such that an upper portion of the MTJ is exposed. A cleaning is performed on the upper portion of the MTJ that is exposed such that any residual material is removed.

Claim (Index 1):
A method of cleaning a magnetic device, the method comprising:\n forming a stack including a magnetic tunnel junction (MTJ), the MTJ including a reference magnetic layer and a free magnetic layer sandwiching a tunnel barrier layer; forming a protective film on a bottom portion of the MTJ such that an upper portion of the MTJ is exposed, wherein a planarizing material is adjacent to the protective film, the planarizing material also being formed on the bottom portion of the MTJ such that the upper portion of the MTJ is exposed; and cleaning the upper portion of the MTJ that is exposed such that any residual material is removed.
