An integrated circuit package is disclosed. The integrated circuit package comprises a first integrated circuit die and a second integrated circuit die. The integrated circuit package further includes a substrate, wherein both the first integrated circuit die and the second integrated circuit die are connected to the substrate. The substrate includes an interconnect bridge embedded within the substrate, wherein the interconnect bridge includes at least one metal trace component, wherein the metal trace component includes rounded corners on a bottom portion of the metal trace component.

Discussed generally herein are methods and devices including or providing a high density interconnect structure. A high density interconnect structure can include a stack of alternating dielectric layers and metallization layers comprising at least three metallization layers including conductive material with low k dielectric material between the conductive material, and at least two dielectric layers including first medium k dielectric material with one or more first vias extending therethrough, the at least two dielectric layers situated between two metallization layers of the at least three metallization layers, a second medium k dielectric material directly on a top surface of the stack, a second via extending through the second medium k dielectric material, the second via electrically connected to conductive material in a metallization layer of the three or more metallization layers, and a pad over the second medium k dielectric material and electrically connected to the second via.

Embodiments of the present invention describe a method and device of preventing delamination of semiconductor layers in a semiconductor device. The semiconductor device comprises a substrate with an interlayer dielectric (ILD). A protection layer is deposited on the ILD. Next, a getter layer is formed on the protection layer to remove any native oxides on the protection layer. A capping layer is then deposited on the getter layer to prevent oxidation of the getter layer. Next, a semiconductor layer is formed on the capping layer. An oxide layer is then deposited on the semiconductor layer. Subsequently, a buffered oxide etch solution is used to remove the oxide layer. By removing the native oxides on the protection layer, the getter layer prevents the reaction between the buffered oxide etch solution and the native oxides which may cause delamination of the semiconductor layer and protection layer.

The fabrication of seek-scan probe (SSP) memory devices involves processing on both-sides of a wafer. However, there are temperature restrictions on the mover circuitry side of the wafer and doping level constrains for either side of wafer. Using a low doped EPI layer on a highly doped substrate solves this issue and provides good STO growth.

A method including forming a photoimageable material on a substrate; developing the photoimageable material over an opening area, the photoimageable material over a first portion of the opening area developed to a first extent and the photoimageable material over a second portion of the opening area developed to a different second extent; removing developed photoimageable material from the opening area; and forming an opening in the substrate in the opening area.

A method comprising introducing a photoimageable material on a substrate; developing the photoimageable material over an opening area, the photoimageable material over a first portion of the opening area developed to a first extent and the photoimageable material over a second portion of the opening area developed to a different second extent; removing developed photoimageable material from the opening area; and forming an opening in the substrate in the opening area.

A method for making a semiconductor device is described. That method comprises forming a copper containing layer on a substrate, then forming a tantalum containing layer on the copper containing layer. After the tantalum containing layer is oxidized, an etch stop layer may be formed on the oxidized tantalum layer.
