The invention relates to a method for manufacturing a film (12) on a support (20) having a non-flat surface, characterised in that it comprises: - the supply of a donor substrate (10) having a non-flat surface, - the formation of an embrittlement zone (11) in the donor substrate (10) so as to delimit said film (12) to transfer, - the formation of the support (20) by conformal deposition on the non-flat surface of the film (12) to transfer, - the detachment of the donor substrate (10) along the embrittlement zone (11), so as to transfer said film (12) onto the support (20).
摘要:
A stack gate structure for a non-volatile memory array has a semiconductor substrate having a plurality of substantially parallel spaced apart active regions, with each active region having an axis in a first direction. A first insulating material is between each stack gate structure in the second direction perpendicular to the first direction. Each stack gate structure has a second insulating material over the active region, a charge holding gate over the second insulating material, a third insulating material over the charge holding gate, and a first portion of a control gate over the third insulating material. A second portion of the control gate is over the first portion of the control gate and over the first insulating material adjacent thereto and extending in the second direction. A fourth insulating material is over the second portion of the control gate.

In an embodiment a second semiconductor layer is transferred (e.g., using layer transfer techniques) on top of a first semiconductor layer. The second layer is patterned into desired wells. Between the wells, the first layer is exposed. The exposed first layer is epitaxially grown to the level of the transferred second layer to complete a planar heterogeneous substrate including both S1 and S2. The heterogeneous materials may be utilized such that, for example, a P channel device formed from one of III-V or IV materials is coplanar with an N channel device formed from one of III-V or IV materials. The embodiment requires no lattice parameter compliance due to the second layer being transferred onto the first layer. Also, there is no (or little) buffer and/or hetero-epitaxy. Other embodiments are described herein.

An integrated circuit may be formed by forming a buried isolation layer in an isolation recess in a single-crystal silicon-based substrate. Exposed lateral surfaces of the substrate at the buried isolation layer are covered with a dielectric sidewall. A seed trench is formed through the buried isolation layer to expose the substrate. A single-crystal silicon-based seed layer is formed through the seed trench, extending above the top surface of the buried isolation layer. A silicon-based non-crystalline layer is formed contacting the seed layer. A cap layer is formed over the non-crystalline layer. A radiant-induced recrystallization process converts the non-crystalline layer to a single-crystal layer aligned with the seed layer. The cap layer is removed and the single-crystal layer is planarized, leaving an isolated semiconductor layer over the buried isolation layer.

A semiconductor device (10) is formed on a semiconductor layer (16). A gate dielectric layer (18) is formed over the semiconductor layer. A layer of gate material (20) is formed over the gate dielectric layer. The layer of gate material is patterned to form a gate structure (20). Using the gate structure as a mask, an implant (24) into the semiconductor layer is performed. To form a first patterned gate structure (20) and a trench (42) in the semiconductor layer (16) surrounding a first portion (28) and a second portion (30) of the semiconductor layer and the gate, an etch through the gate structure (20) and the semiconductor layer (16) is performed. The trench (42) is filled with insulating material (46).
