Motivated by realistic needs to enhance the productivity for 200-mm wafer fabs, this paper aims to propose a novel approach for manual material handling system (MMHS) to mimic functionalities of the automated material handling system in the advanced fabs without intensive capital investment to deliver the wafer lots manually and systematically. In particular, a mathematical model is developed to optimize...
Every enterprise is pursuing energy conservation and carbon reduction development. Under this trend, light-emitting diodes (LEDs) are becoming the focus of the lighting industry. Because of the different levels or types of chips and substrates, the characteristics of products will be different. LED products are categorized according to characteristics such as luminescence efficiency, wavelength (color),...
Capacity planning in semiconductor manufacturing industry is a challenging task due to its high capital investments, volatile demands, and the long lead time. Current approaches to handle this problem are to model it as an optimization problem where the uncertain demand is either based on a single forecast, or is decomposed via a finite-scenario structure with an assigned probability for each scenario...
