Semiconductor wafer fabrication is perhaps one of the most complex manufacturing processes found today. In this paper, we construct a simulation model of part of a wafer fab using ProModel software and analyze the effect of different input variables on selected parameters, such as cycle time, WIP level and equipment utilization rates. These input variables include arrival distribution, batch si...

Wafer fabrication is a capital-intensive high-tech sector with highly complex manufacturing processes. Therefore, most of the fabs resort to production dispatching as a means to enhancing production efficiency. The commonly seen methods of production dispatching at the present time are devised to meet single performance indicators. Few methods take into account multiple, or even conflicting per...

300 mm semiconductor wafer fabrication facilities, like conventional semiconductor fabs, contain many different types of tools. In this paper we discuss a realistic way of representing cluster tools in a simulation model of the entire line. A more realistic representation of cluster tools results in greater accuracy in the output of the simulation model.

We present ramped voltage data from a new nitride used in our fabrication process. Using the same fabrication flow, we measured increased lifetimes for capacitors using this new dielectric. Using the linear field model, this translates into capacitors that can sustain higher applied voltages before they fail.

Manufacturing execution system (MES) is a computer application system that integrates all relevant real-time information along every step in a manufacturing process. MES is essential for manufacturers for gathering real-time production line information, supporting manufacturing decision making and increasing manufacturing efficiency. MES is a must for operation control and lot tracking in the s...

To meet competitive market for the electronics consumer products, the integrated circuit is process at the semiconductor fabrication factory which is the most complex and challenging areas in manufacturing. This is due to semiconductor manufacturers will require to process 300 to 1000 steps depends on products, 60,000 WIP and 400 pieces equipment for typical 200mm wafer size technology. Due to ...

Abstract The advent of additive manufacturing (AM) has brought about radically new ways designing and end-use parts components, by exploiting freedom design. Due to the unique process AM, both design parameters can strongly influence part properties, thereby enlarging possible space. Thus, finding optimal combination embodiment be challenging. A structured systematic approach is required effect...
