    摘要: An electronic device includes a substrate with a semiconducting surface having a plurality of fin-type projections coextending in a first direction through a memory cell region and select gate regions. The electronic device further includes a dielectric isolation material disposed in spaces between the projections. In the electronic device, the dielectric isolation material in the memory cell regions have a height less than a height of the projections in the memory cell regions, and the dielectric isolation material in the select gate regions have a height greater than or equal to than a height of the projections in the select gate regions. The electronic device further includes gate features disposed on the substrate within the memory cell region and the select gate regions over the projections and the dielectric isolation material, where the gate features coextend in a second direction transverse to the first direction.

    摘要: A semiconductor fabrication system and method are presented. A three dimensional multilayer integrated circuit fabrication method can include forming a first device layer and forming a second device layer on top of the first device layer with minimal detrimental heat transfer to the first layer by utilizing a controlled laser layer formation annealing process. A controlled laser crystallization process can be utilized and the controlled laser can include creating an amorphous layer; defining a crystallization area in the amorphous layer, where in the crystallization area is defined to promote single crystal growth (i.e. prevent multi-crystalline growth); and applying laser to the crystallization area, wherein the laser is applied in a manner that prevents undesired heat transfer to another layer.

    摘要: A method for fabricating a memory device with a self-aligned trap layer which is optimized for scaling is disclosed. In the present invention, a non-conformal oxide is deposited over the charge trapping layer to form a thick oxide on top of the core source/drain region and a pinch off and a void at the top of the STI trench. An etch is performed on the pinch-off oxide and the thin oxide on the trapping layer on the STI oxide. The trapping layer is then partially etched between the core cells. A dip-off of the oxide on the trapping layer is performed. And a top oxide is formed. The top oxide converts the remaining trap layer to oxide and thus isolate the trap layer.
