摘要:
An integrated circuit memory device, in one embodiment, includes a substrate and first and second inter-level dielectric layers successively disposed on the substrate. One or more contacts in the peripheral extend through the first inter-level dielectric layer to respective components. One or more vias and a plurality of dummy vias extend through the second inter-level dielectric layer in the peripheral area. Each of the one or more peripheral vias extend to a respective peripheral contact. The peripheral dummy vias are located proximate the peripheral vias.

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.

A system and method for manufacturing a semiconductor device including a low dielectric constant porous material layer. Ions are implanted into the low dielectric constant porous material layer which thereby provides the porous material layer with sufficient mechanical strength for withstanding semiconductor manufacturing processes. The ions implanted in the porous material layer further facilitate disposition of a conductive layer on the porous material layer.

摘要:
Embodiments of the present invention disclose a memory device having an array of flash memory cells with source contacts that facilitate straight word lines, and a method for producing the same. The array is comprised of a plurality of non-intersecting shallow trench isolation (STI) regions that isolate a plurality of memory cell columns. A source column is implanted with n-type dopants after the formation of a tunnel oxide layer and a first polysilicon layer. The implanted source column is coupled to a plurality of common source lines that are coupled to a plurality of source regions associated with memory cells in the array. A source contact is coupled to the implanted source column for providing electrical coupling with the plurality of source regions. The source contact is collinear with a row of drain contacts that are coupled to drain regions associated with a row of memory cells. The arrangement of source contacts collinear with the row of drain contacts allows for straight word line formation.
