Abstract

The powder deposition instrument (PD1) was primarily designed to regulate the flow of silica used in the preparation of amorphous silicon thin films. Since integrated circuits are commonly produced in clean environment, the materials used in the construction of the PDI are vacuum compatible materials. Moreover, the instrument was designed to run with minimal human intervention. When data were gathered using the instrument, it was found that at constant time, the number of revolutions per minute (rpm) is related with mass flow. However, rpm is not very linearly related to mass flow. Thus, with the use of Cubic Spline interpolation we can fit the points found and express mass flow as a cubic equation of rpm. In the second part of the experiment, the relationship of mass flow and time was determined given that rpm is constant. It was found that at fixed rpm, mass flow is linearly related to time. Moreover, if we increase rpm, the slope of the line that defines mass flow and time is steeper. Finally, Multiple Linear Regression was used to express mass as a linear function of time and rpm.
