The Semiconductor manufacturing process for computer chips is a complex sequence of many hundreds of processing steps on silicon wafers.  At a few points in the process, sample wafers are inspected by inspection equipment and defect images reviewed by technicians.  While the basic findings from the inspection tool and technician are fed automatically into a database, other general observations are recorded simply as a comment of several sentences capturing key interpretations of the data. Because of various uses of the information, the comments are entered into multiple databases.

Lean mapping efforts highlighted several improvement opportunities related to these comments: they should be recorded only once and the format of the comment should be standardized. By applying TRIZ functional analysis to the problem, a radically different and innovative improvement was developed.  This improvement demonstrates Altshuller’s key premise that correctly reformulating the problem is vital to an inventive solution. A semantic analysis of all the words of typical comments revealed that these comments had specific functions with certain values to customers of the information.  So the recommended improvement was to eliminate the comment altogether and replace it with a set of categorical choices.  These new fixed field categories are much higher in value to the customers due the new analytic possibilities associated with categorical data.  This paper will show the benefit of this work to the specific semiconductor application as well how the improvements could be applied to any general situation where observations are recorded in sentence structures such as the medical clinical environment.

Case Studies From A Breakthrough Innovation
 
"Starting in August 2004, the Hong Kong government began sponsoring a deployment of TRIZ to a cluster of eight local companies. Over the course of the next 15 months, each company was invited to assemble a team of between 5 and 8 engineers and designers each of whom would be exposed to a series of six three-day TRIZ education and utilization sessions. The aims of the program were for each company to realize new products, patents and tangible financial benefits, and to measure the extent to which TRIZ allowed companies to accelerate their rate of innovation. This paper describes a collection of some of the success stories emerging from the program."

Alexander Selyutsky - a key figure in the history of TRIZ!

Alexander Selyutsky

Selyutsky Alexander Borisovich was born April 6, 1933 to an intelligent Jewish family residing in Leningrad. During the World War II the plant where his father was working was evacuated to the Urals, and the family (the parents and Alexander) moved to Chelyabinsk. Here, Alexander graduated from high school. He wanted to go to a military school, but didn’t pass vision test and entered the Chelyabinsk Polytechnic Institute. In his first year he was forced to learn boxing (because of frequent anti-Semitic attacks) and became a Komsomol activist.

After graduation, he was sent to Petrozavodsk Onega tractor plant, where he worked as a designer. He continued leading a very active social life, organized and led voluntary militia patrolling the streets of the city because the situation was very criminal. In the search for more satisfying work he became interested in patenting, completed appropriate courses and became a patent agent.

In 1960, Alexander married Dolly Naumovna Audleys, and had a daughter Alla in 1961. The same year G.S Altshuller published a book " “Learn how to invent"[1] . After reading this book in 1965 Selyutsky wrote a letter to Altshuller. This letter started their acquaintance by correspondence. Since then, Alexander became one of the most dedicated Altshuller’s disciples and an active promoter of the emerging new science.

They finally met in 1968 in Dzintary (near Riga), at the seminar organized by the Central Board of VOIR (state leading inventors’ and innovators’ society) that invited Altshuller and several of his associates. It was the first time that Alexander and others got a chance to work under the direct guidance of Altshuller and to learn from him. Later, in 1983, Alexander participated as one of the instructors in the seminar conducted by G.S. Altshuller in Moscow at the Institute for continuous education for chemical and petroleum industries.
