Patent ID: 6964751

Claim:
A device for the heat treatment of a series of substrates, comprising a hearing body with a flat surface for accommodating a substrate adjacent to said surface, controllable heating means for heating said heating body, a digital control means, at least one temperature sensor configured to measure the temperature in said heating body and arranged in said heating body near to said flat surface such that withdrawal of heat from said heating body by said substrate is detected, wherein said heating means are connected to said control means, wherein said temperature sensor is connected to said control means, transport means for positioning substrates in the vicinity of said heating body adjacent to said flat surface and for removing substrates therefrom, wherein said transport means are connected to said control means, said control means being provided with extrapolation software for extrapolating over a time interval the temperature measured by said temperature sensor, and said control means arranged in such a way that each of said substrates is positioned in the vicinity of said heating body when the temperature extrapolated over said time interval has reached a desired temperature value.
