摘要: Process for the preparation of thin moncrystalline or polycrystalline semiconductor material films, characterized in that it comprises subjecting a wafer having planar face to three following stages: first stage implantation by bombardment (2) (4) said (1) means ions creating volume layer (3) gaseous microbubbles defining lower region (6) constituting mass substrate and an upper (5) film, second intimately contacting with stiffener (7) constituted at least one rigid layer, third heat treating assembly temperature above which ion was carried out sufficient create crystalline rearrangement effect pressure microbubbles, separation between film (5 ) (6).
