| Summary: | 碩士 === 逢甲大學 === 經營管理碩士在職專班 === 102 === Recently, the TFT-LCD industry is facing the challenges on the
technology competition from Korea and the rapid development of local
brand in Mainland, therefore, the superiority of Taiwan in TFT-LCD
industry is outflowing. In the past, the main suppliers of display were
continuously competing with each others from one generation to another,
such as from G3.5 to G7.5 and G8. In order to expand the production and
monopoly the special size market, the Japanese company Sharp even built
a G10 factory in OSAKA for the LCD industry which is the only one
LCD factory in the world. With more and more factories competing with,
the production ability has been also increased quickly. However, the
competition of this expensive LCD industry will only burden the display
suppliers.
In order to break this situation, Taiwan is now making good use of
different culture, such as devoting some huge size LCD displays
production into the factories at present. In order to help it adapt into the
large size LCD display market, bonding exposure method is must to be
used for the exposure process. However, this technology will still lead to
another problem in the production.
This study focuses on the problem that the company is dealing with.
Using DMAIC methods of Lean Six Sigma can improve the production
process. Besides, this research may also be able to find out the main
factor affecting the quality in the production. By the compensation of the
mask and the substrate temperature as well as changing the total pitch of
the black matrix, the products of the defective rate was decreased from
19.78% to below 3%. Eventually, using the check list, SPC and the
meeting we hold, etc., we can manage the production of the production
line, leading to avoid recurrence. Its annual benefit up to nearly 43
million leads to derive much benefit of the company operations and
increase the competitiveness between each others. In fact, it is really a
successful project by means of Lean Six Sigma.
