Interconnect structures and methods are disclosed. In one embodiment, an interconnect structure includes a via extendable through a workpiece from a first side of the workpiece to a second side of the workpiece. The via is partially filled with a conductive material and has sidewalls. The interconnect structure includes a contact coupled to the conductive material in the via proximate the first side of the workpiece. The conductive material in the via comprises a recessed region comprising a landing zone proximate the second side of the workpiece.

Interconnect structures and methods

According to one embodiment of the present invention, a semiconductor device is provided, that includes a semiconductor carrier; a cavity formed within the semiconductor carrier, the cavity extending from the top surface of the semiconductor carrier into the semiconductor carrier; and at least one semiconductor chip provided within the cavity.

Semiconductor device

The invention relates to a method for producing a rewiring printed circuit board with a substrate wafer having passage connections between a first and a second surface. One embodiment of the method comprises applying and patterning masking layers on the first and the second surfaces, thereby uncovering a first contact location on the first surface and a second contact location on the second surface; applying a protective layer to the second surface in order to protect the corresponding masking layer and the second contact location during subsequent method steps; applying a first conductor structure to the first surface, the first conductor structure on the first surface covering the first contact location; removing the protective layer on the second surface; and applying a second conductor structure to the second surface, the second conductor structure on the second surface covering the second contact location.

Method for producing a rewiring printed circuit board

An electronic component includes compliant elevations having electrical contact areas for contact-connecting the component to an electronic circuit. The compliant elevations are arranged on a surface of the component and the electrical contact areas are arranged on the tip of the compliant elevations. The electrical contact with the electronic circuit is embodied by means of electrical conductive tracks arranged on the surface of the component. The conductive tracks ascend on the outer surfaces of the compliant elevations to the electrical contact areas.

Electronic component with compliant elevations having electrical contact areas and method for producing it

A method for forming printed re-routing for wafer level packaging, especially chip size packaging. The method includes forming a contact layer on a semiconductor die, printing a conductive redistribution structure on the contact layer, and etching the contact layer of the die by using the conductive redistribution structure as a self-aligning mask.
