Claim 1
Independent Claim
90 words
A RADIATION-SENSITIVE TARGET COMPRISING A SURFACE OF ELECTRICALLY-INSULATING MATERIAL, A RADIATION-SENSITIVE COATING APPLIED TO A PART OF SAID SURFACE, A CONDUCTIVE COATING APPLIED OVER SAID RADIATION-SENSITIVE COATING AND LEAVING EXPOSED A PORTION OF SAID RADIATION-SENSITIVE COATING, INSULATING SCRIBE LINES SEPARATING THE EXPOSED PORTION OF SAID RADIATION-SENSITIVE COATING INTO A PLURALITY OR RADIATION-SENSITIVE ELEMENTS AND EXTENDING INTO SAID CONDUCTIVE COATING, THE DISTANCE BETWEEN TWO SCRIBE LINES SEPARATING A GIVEN RADIATION-SENSITIVE ELEMENT BEING GREATER IN AT LEAST PART OF SAID CONDUCTIVE COATING THAN IT IS THE EXPOSED PORTION OF SAID RADIATION-SENSITIVE COATING.
