Wafer Fabrication Expert Witnesses

Start Wafer Fabrication Expert Search

Wafer fabrication expert witness candidates typically hold advanced degrees in electrical engineering, with specific expertise in semiconductor fabrication, semiconductor material, semiconductor equipment, and/or the semiconductor industry. A wafer fabrication expert witness must have a deep understanding not only of the manufacturing process, but also of the semiconductor device market, market share and the developing technologies of the industry’s leading players.

Basic information on technology and the semiconductor manufacturing equipment market is available through a market report from an industry analysis provider. But a wafer fabrication expert witness must have a deeper understanding of the history, the progression of the technology and often an understanding of which competitors were working on various designs at different points of time during the initial development stage.

While many competent consultants have the basic knowledge to get the job done, the expert witness carries the additional responsibility of providing testimony before the court, in a manner whereby lay people (the judge and every juror) can understand the technical nuances, such to make an informed decision.

An expert witness in this field will typically provide his or her expertise in intellectual property matters — a patent litigation in the federal court. It could be a patent infringement case in the District Court, an Inter Partes Review (IPR) in the PTAB (where the only expert testimony is through a deposition), or a patent case or proceeding in the International Trade Commission (ITC).

A testifying expert, or expert witness, is generally the only one in the court who is allowed to provide testimony as to his or her opinion — because it is an expert opinion. Regardless of whether this takes the form of testimony in a deposition or trial, or in an expert report, the engineering component will provide credibility to his or her analysis and allow the jury to consider the expert’s opinion with the weight it deserves. Cahn Litigation Services has completed numerous searches for an expert witness in the semiconductor and wafer fabrication space, providing candidates for each case to the specifications provided by the attorney in charge. Whether it’s for a semiconductor patent case, or for pre-litigation reverse engineering or failure analysis, Cahn Litigation Services has the experience required to turn the search around quickly and provide the right balance of expertise and testimony to get the job done.

Expert Witness #256772

This expert received bachelor's and master's degrees in Electrical and Electronic Engineering and a Ph.D. in Electrical Engineering and Computer Science. This expert's thesis advisor is widely regarded as one of the world's foremost experts in CMP. This expert participated in weekly group meetings and CMP project-specific meetings, in which CMP mechanics, materials and modeling projects were discussed and participants put forward interpretations of data, suggested experimental designs, and debated modeling approaches. This experience provided his initial grounding in and understanding of the field of CMP.

This expert's thesis work was on the topic of nanoimprint lithography (NIL), a semiconductor manufacturing process which has a number of physical commonalities with CMP. Both NIL and CMP involve mechanical contact between two solid bodies separated by a fluid layer (wafer/slurry/pad in CMP and wafer/resist/stamp in NIL), and in both processes, mechanical deformations of the solid bodies need to be understood and controlled to ensure that manufactured semiconductor devices are within dimensional specifications.

This expert has been working with one of the world's leading manufacturers of CMP equipment to model and simulate CMP using novel pad geometries. These pads are composed of multiple materials with heterogeneous properties.
