发明名称 Method and structure for fabricating solar cells using a layer transfer process
摘要 A reusable silicon substrate device for use with layer transfer process. The device has a reusable substrate having a surface region, a cleave region, and a total thickness of material. The total thickness of material is at least N times greater than a first thickness of material to be removed. In a specific embodiment, the first thickness of material to be removed is between the surface region and the cleave region, whereupon N is an integer greater than about ten. The device also has a chuck member adapted to hold a handle substrate member in place. The chuck member is configured to hold the handle substrate in manner to facilitate bonding the handle substrate to the first thickness of material to be removed. In a preferred embodiment, the device has a mechanical pressure device operably coupled to the chuck member. The mechanical pressure device is adapted to provide a force to cause bonding of the handle substrate to the first thickness of material to be removed.
