Abstract: A dopant funnel for loading dopant pellets into a dispenser tube of a dopant dispenser is disclosed. The dopant funnel has a cup connected through a restrictor to a shaft. The cup holds random oriented dopant pellets. The restrictor meters the amount and orientation of dopant pellets being removed from the cup. The shaft is in alignment with the restrictor for delivering dopant pellets from the cup to the dispenser tube.
