  • Patent number: 8841141
    Abstract: A method for separating a multiple number of semiconductor devices or semiconductor integrated circuits from a wafer on which the multiple number of semiconductor devices or semiconductor integrated circuits are formed is provided. The method includes: forming, on a surface of the wafer, a mask layer through which a line-shaped pattern to be removed for separating the semiconductor devices or semiconductor integrated circuits is exposed; and etching the exposed pattern to a depth equal to or larger than about ? of a thickness of the wafer. The line-shaped pattern is formed so as to prevent a test device formed on a gap between the semiconductor devices or semiconductor integrated circuits from remaining on separated semiconductor devices or semiconductor integrated circuits.

  • Patent number: 7769617
    Abstract: A worker management system, which includes a plant 100 divided into a plurality of work areas each in correspondence to specific task contents, a database 220 having stored therein task identification information correlating each work area 112 with contents of tasks performed therein and worker detection sensors 130 installed in each work area, identifies the specific work area where a worker is currently located based upon outputs from the worker detection means and then identifies the task currently performed by the worker based upon the task identification information. Based upon the current task thus identified, a decision is made as to whether the worker should continue the current task or be assigned a new task and an instruction for task execution is issued to the worker. Therefore the identification of current tasks, the assignment of a new task and the task reassignment are facilitated to improve the work efficiency.

  • Patent number: 7682517
    Abstract: A method of processing a substrate that enables the amount removed of a surface damaged layer to be controlled easily, and enable a decrease in wiring reliability to be prevented. A surface damaged layer having a reduced carbon concentration of a carbon-containing low dielectric constant insulating film on a substrate is exposed to an atmosphere of a mixed gas containing ammonia and hydrogen fluoride under a predetermined pressure. The surface damaged layer that has been exposed to the atmosphere of the mixed gas is heated to a predetermined temperature.
