A method to operate an apparatus for feeding liquid metal to an evaporator device in a vacuum chamber, wherein the feed tube runs from a container adapted to contain a liquid metal to the evaporator device and wherein an electromagnetic pump is provided in the feed tube and a valve in the feed tube between the electromagnetic pump and the evaporator device. An at least partially gas permeable electromagnetic pump, which is enclosed in a pressure controlled enclosure, is used in the method wherein electromagnetic pump and the pressure controlled enclosure are controlled such that filling and draining of the evaporator device and feed tube can be done without affecting the vacuum pressure in the vacuum chamber.

Method to operate an apparatus for feeding liquid metal to an evaporator device

A method to control the temperature of an electromagnetic pump in an apparatus wherein a liquid metal is supplied through a feed tube from a container adapted to contain a liquid metal to an evaporator device in a vacuum chamber, wherein the temperature of the electromagnetic pump is controlled by controlling one or more of

Method to control the temperature of an electromagnetic pump

An apparatus for feeding liquid metal to an evaporator device in a vacuum chamber, wherein the apparatus includes a container adapted to contain a liquid metal, a feed tube from the closed container to the evaporator device and an electromagnetic pump provided in the feed tube, and wherein the electromagnetic pump is placed in a vacuum enclosure.

Apparatus for feeding a liquid material to an evaporator device

A filter device for reducing the amount of non-vaporous components in a vapour stream, including a carbon foam as filter material capable of being penetrated by the vapour stream and arranged in such a way that the only route for the vapour stream to pass the carbon foam is via penetration of the carbon foam. The device is in particular suitable for coating a substrate by physical vapour deposition of the vapour. The homogenous and single phase vapour stream produced by the filter device results in a smooth coated substrate wherein splashes are virtually absent.
