Abstract: A micro-connection structure is provided. The micro-connection structure includes an under bump metallurgy (UBM) pad, a bump and an insulating ring. The UBM pad is electrically connected to at least one metallic contact of a substrate. The bump is disposed on the UBM pad and electrically connected with the UBM pad. The insulating ring surrounds the bump and the UBM pad. The bump is separate from the insulating ring with a distance and the bump is isolated by a gap between the insulating ring and the bump.

Abstract: A method includes depositing a plurality of layers on a substrate, patterning a first mask overlying the plurality of layers, and performing a first etching process on the plurality of layers using the first mask. The method also includes forming a polymer material along sidewalls of the first mask and sidewalls of the plurality of layers, and removing the polymer material. The method also includes performing a second etching process on the plurality of layers using the remaining first mask, where after the second etching process terminates a combined sidewall profile of the plurality of layers comprises a first portion and a second portion, and a first angle of the first portion and a second angle of the second portion are different to each other.

Abstract: A method for forming a semiconductor device is provided. The method includes providing a substrate. The method includes forming a mask layer over a surface of the substrate. The mask layer has an opening over a portion of the surface. The method includes depositing a conductive layer over the surface and the mask layer. The method includes removing the mask layer and the conductive layer over the mask layer. The conductive layer remaining after the removal of the mask layer and the conductive layer over the mask layer forms a conductive pad. The method includes bonding a device to the conductive pad through a solder layer. The conductive pad is embedded in the solder layer.
