More efficient use of silicon area is achieved by incorporating an electrostatic discharge protective (ESDP) device beneath a pad area of a semiconductor structure. The pad area includes a substrate having a first metal layer above it. A second metal layer is above the first metal layer. The ESDP device resides in the substrate below the first metal layer. A layer of dielectric separates the first and second metal layers. A via within the dielectric layer electrically couples the first and second metal layers. A via connects to the ESDP component. Subsequent metal layers can be arranged between the first and second metal layers. The Ohmic value of the resistance component of the ESDP device can be set during fabrication by fixing a number of individual via components, arranged electrically in parallel, by fixing the cross sectional area of the via components, and/or by fixing the length of the via components.

According to one exemplary embodiment, a floating gate memory cell comprises a stacked gate structure situated on a substrate and situated over a channel region in the substrate. The floating gate memory cell further comprises a recess formed in the substrate adjacent to the stacked gate structure, where the recess has a sidewall, a bottom, and a depth. According to this exemplary embodiment, the floating gate memory cell further comprises a source situated adjacent to the sidewall of the recess and under the stacked gate structure. The floating gate memory cell further comprises a Vss connection region situated under the bottom of the recess and under the source, where the Vss connection region is connected to the source. The Vss connection region being situated under the bottom of the recess causes the source to have a reduced lateral diffusion in the channel region.

Moisture seal apparatus and methodologies are disclosed for protecting semiconductor devices from moisture. An upper seal layer, such as SiN is formed over an upper insulator layer and an exposed portion of a die seal metal structure so as to form a vertical moisture seal between electrical components in the semiconductor device and the ambient environment. A lateral seal may be formed from the die seal metal structure in an upper metal layer in the device and one or more contacts extending downward from the die seal metal to the substrate or to a lower die seal metal structure.

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.
