Abstract: A 3D stacked multichip module comprises a stack of W IC die. Each die has a patterned conductor layer, including an electrical contact region with electrical conductors and, in some examples, device circuitry over a substrate. The electrical conductors of the stacked die are aligned. Electrical connectors extend into the stack to contact landing pads on the electrical conductors to create a 3D stacked multichip module. The electrical connectors may pass through vertical vias in the electrical contact regions. The landing pads may be arranged in a stair stepped arrangement. The stacked multichip module may be made using a set of N etch masks with 2N-1 being less than W and 2N being greater than or equal to W, with the etch masks alternatingly covering and exposing 2n-1 landing pads for each mask n=1, 2 . . . N.

Abstract: A method of fabricating a semiconductor device is provided. The method comprises: (a) providing a first and a second conductor; (b) providing a conductive layer; (c) forming a part of the conductive layer into a data storage layer by a plasma oxidation process, wherein the data storage layer is positioned between the first and the second conductor.

Abstract: A flash memory cell includes a silicon substrate having a main surface, a source region in a portion of the silicon substrate proximate the main surface and a drain region in a portion of the silicon substrate proximate the main surface. The drain region is spaced apart from the source region. The memory cell includes a first dielectric layer formed on the main surface, a floating gate disposed above the first dielectric layer, an inter-gate dielectric layer disposed above the floating gate, a control gate disposed above the inter-gate dielectric layer, a second dielectric layer and a low-k dielectric spacer layer disposed on the second dielectric layer. The first dielectric layer covers a portion of the main surface between the source and the drain. The second dielectric layer surrounds outer portions of the first dielectric layer, the control gate, the inter-gate dielectric layer and the floating gate.
