摘要： A method to form elevated source/drain (S/D) over staircase shaped openings in insulating layers. A gate structure is formed over a substrate. The gate structure is preferably comprised of a gate dielectric layer, gate electrode, first spacers, and hard mask. A first insulating layer is formed over the substrate and the gate structure. A resist layer is formed having an opening over the gate structure and over a lateral area adjacent to the gate structure. We etch the insulating layer through the opening in the resist layer. The etching removes a first thickness of the insulating layer to form a source/drain (S/D) opening. We remove the first spacers and hardmask to form a source/drain (S/D) contact opening. We implant ions into the substrate through the source/drain (S/D) contact opening to form lightly doped drain regions. We form second spacers on the sidewalls of the gate electrode and the gate dielectric and on the sidewalls of the insulating layer in the source/drain (S/D) contact opening and the source/drain (S/D) opening. A conductive layer is deposited over the gate electrode, the insulating layer. The conductive layer is planarized to exposed the insulating layer to form elevated source/drain (S/D) blocks on a staircase shape insulating layer.

Gate dielectric spacers are formed over the sidewalls of the gate layer. Then, we form a conductive plug filling the gate opening. The insulating layer is removed. We form a drain region in top and side portions of the conductive plug and form doped gate regions in the gate layer. The remaining portions of the conductive plug comprise a channel region. A channel length is between the top of the source region and the drain region. We form an interlevel dielectric layer over the barrier layer, the gate layer, and the conductive plug.

摘要： The invention describes three embodiments of methods for forming a balloon shaped STI trench. The first embodiment begins by forming a barrier layer over a substrate. An isolation opening is formed in the barrier layer. Next, ions are implanted into said substrate through said isolation opening to form a Si damaged or doped first region. The first region is selectively etching to form a hole. The hole is filled with an insulating material to form a balloon shaped shallow trench isolation (STI) region. The substrate has active areas between said balloon shaped shallow trench isolation (STI) regions. The second embodiment differs from the first embodiment by forming a trench in the substrate before the implant. The third embodiment forms a liner in the trench before an isotropic etch of the substrate through the trench.
