Method for the fabrication of sensor arrays with individually different sensing surface, where lift off technique and shadow mask technique is used simultaneously. A resist layer with openings at all locations where coatings are intended is applied with lift off technique. Then a shadow mask is used provided with windows only at the openings where deposit is intended for one specific coating. By for instance vapor deposition, coatings are effected where there are openings in the resist and windows in the shadow mask. The shadow mask is moved to the next depositions location and the procedure repeated until all coatings have been effected. The shadow mask is removed as is also the resist giving an improved sensor quality compared to prior-art methods. <IMAGE> |
