摘要:
A microelectromechanical system (MEMS) device includes a high density getter. The high density getter includes a silicon surface area formed by porosification or by the formation of trenches within a sealed cavity of the device. The silicon surface area includes a deposition of titanium or other gettering material to reduce the amount of gas present in the sealed chamber such that a low pressure chamber is formed. The high density getter is used in bolometers and gyroscopes but is not limited to those devices.

The invention proposes a method for transferring a thin layer of semiconductor material on a substrate by the SMARTCUTTM type process, the method being characterized in that the implantation step comprises: a first implantation operation consisting in carrying out an implantation of species so as to create said embrittlement zone at a first depth in the thickness of the donor substrate; a second implantation operation consisting in carrying out an implantation of species according to second implantation conditions chosen to create: - at a second depth different from said first depth so as not to affect the detachment that has to take place at the level of the embrittlement zone at said first depth, gettering region preventing the diffusion of species implanted during said first implantation operation towards said face of the donor substrate under which implantation is carried out, thus limiting blisters formation.

In a SOI structure semiconductor device using a SOI substrate 100, a lattice distortion layer 4 is formed by implanting Ar ions into a silicon substrate as an active layer 3. The lattice distortion layer 4 is capable of serving as a gettering site. The dose amount of Ar ions is adjusted in such a manner that tensile stress in the lattice distortion layer 4 is equal to or greater than 11MPa and equal to or less than 27MPa. Thus, the lattice distortion layer 4 can prevent occurrence of a leakage current while serving as the gettering site.
