  • Regular array of microscopic structures on a substrate and devices incorporating same
    Patent number: 7008862
    Abstract: A regular array and method of forming a substantially regular array of microscopic structures on a surface of a sample is described. A device of the present invention comprises a microscopic layer of at least one first material on a substrate of a second material, wherein the microscopic layer is sufficiently thin that stress fields at the interface of the microscopic layer and the substrate cause formation of separated regions of the first material on the substrate. The microscopic layer on the sample is irradiated by means of a particle beam at an acute angle to influence the direction of alignment of the separated regions and/or the relative position of adjacent the separated regions.
    Type: Grant
    Filed: November 14, 2003
    Date of Patent: March 7, 2006

  • Method of forming regular array of microscopic structures on a substrate
    Patent number: 6649491
    Abstract: A method of forming a substantially regular array of microscopic structures on a surface of a sample (4) is described. The sample comprises a microscopic layer of at least one first material on a substrate of a second material, wherein the microscopic layer is sufficiently thin that stress fields at the interface of the microscopic layer and the substrate cause formation of separated regions of the first material on the substrate. The microscopic layer on the sample (4) is irradiated by means of a particle beam (5) at an acute angle &agr;, to influence the direction of alignment of said separated regions and/or the relative position of adjacent said separated regions.
