摘要:
A method of selectively locating a barrier layer on a substrate includes forming a barrier layer on a surface of the substrate. The barrier layer comprises of a metal element and a non-metal element. The barrier layer may also be formed from a metal element and non-metal element. The method further includes forming an electrically conductive film layer on the barrier layer, and forming a metallic portion in the electrically conductive film layer. The method further includes selectively ablating portions of the barrier layer from the dielectric layer to selectively locate place the barrier layer on the substrate.

A laser etching system includes a laser source configured to generate a plurality of laser pulses during an etching pass. A workpiece is aligned with respect to the laser source. The workpiece includes an etching material that is etched in response to receiving the plurality of laser pulses. A mask reticle is interposed between the laser source and the workpiece. The mask reticle includes at least one mask pattern configured to regulate the fluence or a number of laser pulses realized by the workpiece such that a plurality of features having different depths with respect to one another are etched in the etching material.

An ablation system includes an ablation tool configured to generate an energy beam to ablate an energy-sensitive material formed on at least one embedded feature of a workpiece. The ablation tool selects an initial fluence and an initial pulse rate of the energy beam to ablate a first portion of the energy-sensitive layer. The ablation tool further reduces at least one of the initial fluence and the initial pulse rate of the energy beam to ablate a second remaining portion of the energy-sensitive layer such that the embedded feature is exposed without being damaged or deformed.

An integrated circuit (IC) device tester includes contact probes. A liner is formed upon the contact probes. The liner includes a matrix of metal particles and glass particles. The metal particles of the liner allow the contact probe to pass an electrical current through the liner. The glass particles of the liner prevent C4 material from adhering to the liner.

A module includes a laminate, the laminate including a solder mask layer and at least one depression in an upper surface of the solder mask layer that does not pass all of the way through the solder mask layer. The module also includes a first electronic element disposed in a first of the at least one depressions.
摘要:
A semiconductor structure includes an electrically conductive structure formed upon an uppermost organic layer of a semiconductor substrate. A capping layer is formed upon the uppermost organic layer covering the electrically conductive structure. A maskless selective removal lasering technique ejects portions of the capping layer while retaining the portion of the capping layer covering the electrically conductive structure. Portions of the capping layer are ejected from the uppermost organic layer by a shockwave as a result of the laser beam vaporizing the uppermost organic layer of the semiconductor substrate. Portions of the capping layer contacting the electrically conductive structure are retained by the conductive structure dissipating heat from the laser that would otherwise vaporize the uppermost organic layer of the semiconductor substrate.
