发明名称 Device for measuring alignment of adjoining structures
摘要 The invention relates to the field of micro- and nanotechnologies. In these techniques, it is sometimes necessary to glue several structures face to face and it is important to be able to check the alignment of the structures. A new method for measuring alignment, which comprises the following operations, is proposed for this purpose: activation of a heating element placed on the surface of the first structure, generation of electronic signals representative of a distribution of temperatures, on the basis of an array of temperature sensitive elements placed on the surface of the second structure, determination of a relative position of the heating element with respect to the array of sensitive elements, therefore of the first structure with respect to the second, on the basis of the distribution of temperatures, in a calculation circuit receiving the electronic signals engendered in the array of sensitive elements.
