摘要:
An apparatus for treating wafers, provided with at least one treatment chamber, the apparatus being provided with a feeding section in which wafers contained in a wafer storage box can be fed into the apparatus, the apparatus being provided with a wafer handling apparatus, by means of which wafers can be taken out of the wafer storage boxes so as to be treated in the treatment chamber, and the apparatus being provided with at least one sensor box arranged such that the wafer handling apparatus can feed a wafer into the sensor box through an opening provided for that purpose in the at least one sensor box, and the at least one sensor box being arranged to carry out measurements at a wafer, wherein the at least one sensor box is movably arranged and the apparatus is provided with a sensor box handling apparatus arranged to move the at least one sensor box from a storage position to a measuring position.

Storage assembly provided with a robot for placing cassettes, which are filled with wafers, in a carousel, comprising a number of magazines. These magazines lie both above one another and next to one another. In order to be able to determine the correct position of the head of the robot which holds the cassettes with respect to the magazines, it is proposed to provide sensor means which determine the vertical position of the head with respect to the base plate of the magazines and sensor means for determining the horizontal position of the head with respect to the magazines. This horizontal position is determined using openings arranged in the base plate of the magazines. In particular, a main opening and an auxiliary opening are present.

A gas supply system for pulse-wise feeding a reactant gas to a reactor, the gas supply system comprising:
a first valve (300) being a four-port diaphragm valve; a second valve (500) which in an open state brings the first port (30) into fluid communication with an exhaust and in a closed state closes off said fluid communication; wherein the gas supply system provides a reactant flow state in which the first valve (300) is in an open state and the second valve (500) is in a closed state, and wherein the gas supply system provides a purge state in which the first valve (300) is closed and the second valve (500) is in an open state. Also disclosed are a method of switching a process fluid by operating a gas supply system according to the invention and a valve assembly for use in such a gas supply system.

Titanium nitride (TiN) films are formed in a batch reactor (10) using titanium chloride (TiCl 4 ) and ammonia (NH 3 ) as precursors. The TiCl 4 is flowed into the reactor (10) in temporally separated pulses. The NH 3 can also be flowed into the reactor (10) in temporally spaced pulses which alternate with the TiCl 4 pulses, or the NH 3 can be flowed continuously into the reactor (10) while the TiCl 4 is introduced in pulses. The resulting TiN films exhibit low resistivity and good uniformity.
