Abstract
Semiconductor Testing industry belongs to back end of Semiconductor Supply Chain, and the characteristic of industry is highly requirement of manpower、technique & capital. To face the challenge of the low marginal profit age coming recently, the operation cost control is key factor of industrial competition. Equipment related cost & expense have reached 70% higher of the testing house operation cost, that is, the management of equipment related cost & expense is a must do for testing house decision level. The major component of equipment related cost is depreciation cost and maintain expense, therefore the supporting from equipment and parts vendor is very important in high technique requirement industry. This research focus on key equipment & parts of logic testing industry, collecting & analysis the data come from other research、industrial paper、newspaper & case study testing house, summarize the information & relation of testing industry & their vendor, and define vendor management strategy in a testing house, then using AHP ( Analytic Hierarchy Process ) to quickly determine the vendor evaluation & ranking result. After the case study of a testing house, we approved the strategy and evaluation method is very helpful for the case company. And the summary of the research as below :1. Key equipment & parts of Logic Testing Industry is : Tester、Handler、Prober & Probe Card.2. The self-repair capability of key equipment & parts is an important mission for current logic testing industry. The capability can help factory quickly recover the down time and keep smooth production.3. The strategy for logic testing house to their tester vendor : co-work with tester vendor for developing platform conversion technique, let product can testing on other platform for scheduling flexibility.4. The strategy for logic testing house to their handler & prober vendor : Using the increasing order requirement to create a competitive environment market for bargaining price & service, enhance the flexibility of production & cultivate local vendor for future low cost consideration.5. The strategy for logic testing house to their probe card vendor : Using the increasing order requirement to create a competitive environment market for bargaining and service, Obtain the high level probe card repair technique to avoid production break down loss when wafer sort business ramp up in near future.6. The Vendor management model & AHP method used in this research are helpful for logic testing house after real case implement proven.This research can be a reference paper for testing industry research & vendor evaluation related research.
