         6 . A method as in  claim 4  further comprising: 
 applying said low vacuum pressure to said low vacuum channel to lift said excess blocks off said substrate; and    applying said high vacuum pressure to said high vacuum channel to remove said excess blocks off said substrate.    
     
     
         7 . A method as in  claim 3  further comprising: 
 pulsating a dispensing device that dispenses a slurry comprising a plurality of blocks wherein said slurry include said excess blocks while dispensing said plurality of blocks over a substrate having a plurality of receptor sites to receive said plurality of blocks.    
     
     
         8 . A method for moving a plurality of blocks comprising: 
 removing excess blocks off a substrate having a plurality of blocks being dispensed thereto with a block clearing device, said block clearing device comprising a fluid container and a compression device, wherein said fluid container releases a fluid to over said substrate while said compression member causes said fluid to pulsate as said fluid is being released.    
     
     
         9 . A method as in  claim 8  wherein said removing excess blocks off said substrate includes alternately jetting out and taking in said fluid to create a net flow rate of approximately zero.  
     
     
         10 . A method as in  claim 8  further comprising: 
 using a dispensing device and dispensing a slurry having said plurality of blocks over said substrate, said substrate further having a plurality of receptor sites to receive said plurality of blocks; and    while dispensing said slurry, pulsating said slurry.    
     
     
         11 . A method comprising: 
 moving a slurry from a first process chamber to a second process chamber using a pressure regulation mechanism, said slurry comprising a plurality of blocks dispensed in a fluid, each of said plurality of blocks having integrated circuits disposed thereon; and    performing an action on at least one block, said action is one of cleaning said at least one block or treating said at least one block.    
     
     
         12 . A method as in  claim 11  further comprising cleaning at least one block of said plurality of blocks in said first process chamber.  
     
     
         13 . A method as in  claim 11  further comprising treating at least one block of said plurality of blocks in said second process chamber.  
     
     
         14 . A method as in  claim 11 , wherein said first chamber is selected from a group consisting a recovering station, a recycling station, a dispensing station, and a cleaning station.  
     
     
         15 . A method as in  claim 11 , wherein said second chamber is selected from a group consisting of a recovering station, a recycling station, a dispensing station, and a cleaning station.  
     
     
         16 . A method for dispensing a plurality of blocks over a substrate comprising: 
 dispensing a slurry having said plurality of blocks and a fluid into a dispensing tube having a plurality of orifices;    vibrating said slurry using a vibration source coupling to said dispensing tube while dispensing said plurality of blocks to a substrate having a plurality of receptor sites to receive said plurality of blocks, said plurality of blocks are dispensed through said plurality of orifices.    
     
     
         17 . A method as in  claim 16  wherein said vibration and said slurry comprises said vibration source vibrating said slurry with frequencies ranging from 2 HZ to 2000 HZ.  
     
     
         18 . A method as in  claim 16  further comprising rotating said dispensing tube using a rotation mechanism compiling to each side of dispensing tube.  
     
     
         19 . A method as in  claim 18  wherein said rotating includes rotating said dispensing tube from a 0-degree position to a 90-degree position.  
     
     
         20 . A method as in  claim 18  wherein said rotating includes rotating said dispensing tube such that said plurality of orifices face downward and directly above said substrate to dispense said plurality of blocks.  
     
     
         21 . A method as in  claim 18  wherein said rotating includes rotating said dispensing tube such that said plurality of orifices face away from said substrate to stop dispensing said plurality of said blocks over said substrate.  
     
     
         22 . A method as in  claim 16  further comprising: 
 dispensing said slurry into a transfer chamber located within said dispensing tube through an inlet tube disposed into a first end of said transfer chamber;    removing excess fluid from said slurry from said transfer chamber through an outlet tube coupled to a second end of said chamber using a vacuum source compiling to said outlet tube and turning off said vacuum source to distribute said plurality of blocks over said plurality of orifices.    
     
     
         23 . A method as in  claim 16  further comprising:
