Process for precise arrangement of micro-bodies

Abstract

A process for arranging a number of micro-bodies efficiently and precisely as one on one spot on a substrate. Charged spots are formed by a converging ion beam or the like on a substrate having an insulating property or the like, and micro-bodies having a size of 200 microns or less are attracted and stuck to the charged spots.

What is claimed is:  
     
         1 . A process for arranging a micro-body precisely, comprising: forming a charged spot on an insulating substrate; and attracting and sticking one micro-body to one charged spot.  
     
     
         2 . A process for arranging a micro-body precisely according to  claim 1 , 
 wherein said micro-body has a size of no more than 400 microns.    
     
     
         3 . A process for arranging a micro-body precisely according to  claim 1 , 
 wherein said charged spot has a size of no more than 100 microns.    
     
     
         4 . A process for arranging a micro-body precisely according to  claim 1 , 
 wherein said charged spot is polarized positive or negative in or out of contact.    
     
     
         5 . A process for arranging a micro-body precisely according to  claim 1 , 
 wherein a plurality of charged spots are formed, and wherein one micro-body is attracted and stuck to each of said charged spots.    
     
     
         6 . A process for arranging a micro-body precisely according to  claim 1 , 
 wherein a positively charged spot smaller than a micro-body having a size of 1 to 200 microns is formed on said insulating substrate by a converging ion beam, and wherein said microbody is arranged on said charged spot.    
     
     
         7 . A process for arranging a micro-body precisely according to  claim 1 , 
 wherein a negatively charged spot smaller than a micro-body having a size of 10 to 200 microns is formed on said insulating substrate by a converging electron beam, and wherein said micro-body is arranged on said charged spot.    
     
     
         8 . A process for arranging a micro-body precisely according to  claim 1 , 
 wherein a positively or negatively charged spot is formed on said insulating substrate by a discharge of a conductive microprobe having a leading end in or out of contact with said insulating substrate, and wherein a micro-body having a size of 0.1 to 200 microns is arranged on said charged spot.    
     
     
         9 . A process for arranging a micro-body precisely according to  claim 8 , 
 wherein a multiplicity of charged spots are simultaneously formed by integrating micro-probes into an array, and wherein micro-bodies are arranged on the individual charged spots.    
     
     
         10 . A process for arranging a micro-body precisely, comprising: establishing a spot electric field by polarizing a substrate of a ferroelectric body voluntarily; and attracting and sticking one micro-body to said spot electric field.
