Abstract:
PROBLEM TO BE SOLVED: To provide a material sample (TEM-"lamella") suitable for transmission electron microscopy (TEM) studies and in particular an HRTEM-lamella (HR means high resolution), a process for manufacturing the same, and an apparatus for executing the process.SOLUTION: The process for manufacturing a TEM-lamella comprises: a step (S1) of mounting a substrate having a thickness on a support; a step (S3) of manufacturing a first strip-shaped recess on a first side of the substrate at a first angle to the support by using a particle beam; and a step (S5) of manufacturing a second strip-shaped recess on a second side of the substrate at a second angle to the support by using the particle beam. The first and the second strip-shaped recess are manufactured so as to form a thin overlap region. The lamella has a thick rim region and a thin central region, has the first strip-shaped recess on a first flat surface thereof, and has the second strip-shaped recess on a second flat surface thereof. The first and the second strip-shaped recess mutually form an acute or right angle.

Abstract:
PROBLEM TO BE SOLVED: To provide a conveying device of a mini-environment system efficiently conveying a sample to a scanning electron microscope for critical dimension measuring, even when an SMIF-pod (standard mechanical interface-pod) housing only one piece of photomask is used. SOLUTION: A storage box capable of housing a plurality of photomasks is provided differently from a load port on a conveying device of a mini-environment system. A mask housing shelf having a plurality of housing units stacked thereon is provided in the storing box, and each of the housing units houses one piece of photomask. Each of the housing units is provided with a sensor for determining whether the photomask is correctly housed. Further, each of the housing units is provided with a sensor for detecting the presence or absence of the photomask. COPYRIGHT: (C)2008,JPO&INPIT
