Title: Inspecting method for semiconductor integrated circuit
Inventor: MIZUTANI TETSUO
IPC: G01R31/316
Filed: 1981-07-01
Abstract: PURPOSE:To prevent a sealing vessel for a semiconductor integrated circuit from becoming large-sized, by a method wherein a voltage different from a supply voltage is impressed selectively on one of power supply terminals to put the circuit in an inspection mode through the intermediary of an incorporated inspection circuit and thereby to unnecessitate a terminal used exclusively for inspection. CONSTITUTION:When a power supply terminal VSS whereon a high-level normal voltage is impressed ordinarily is fixed at an earthing level forcibly, the level of a signal sent into an inspection circuit 2 incorporated in a semiconductor integrated circuit by a Schmitt circuit 3, an inverter 4, etc. is changed from high to low. By this change, the operation of the circuit 2 is enabled and thereby the semiconductor integrated circuit is put in an inspection mode. By a constitution wherein said terminal is used commonly for ordinary and testing operations by changing a voltage impressed thereon, it is unnecessitated to provide a terminal used exclusively for testing, which is not employed ordinarily, and thus a sealing vessel for the semiconductor integrated circuit is prevented from becoming large- sized.

Title: Charged particle beam device
Inventor: OKUNUKI MASAHIKO
IPC: H01J37/305
Filed: 1987-04-28
Abstract: PURPOSE:To enhance a processing speed by a method wherein, when a pattern data is supplied to a charged particle beam generation source, it is transferred via more than two data storage means so that the waiting time of the data at the charged beam generation source is eliminated. CONSTITUTION:If the information designed by a controller CAD is sent out to a one- chip pattern generator PG, the generator PG divides the drawing information on one chip into the drawing information for an upper half and that for a lower half and sends these two pieces of information to individual 1/2 chip memories MU, ML alternately. Because the memories MU, ML are used alternately in this manner, it is possible to substantially eliminate a loss of the time during a data transfer from the generator PG. While each EB source is defelected by its X-direction deflecting electrodes X1, X2 in an X-direction and executes a drawing operation in the X-direction within a range to be covered by a deflection on the basis of the drawing information for the upper half from the memories MU, ML, a wafer WF and a head MB are continuously shifted relatively in a Y-direction. By this setup, all picture elements in the Y-direction in a 1/2 region are drawn. If the drawing operation is repeated while the wafer WF and the head MB are intermittently shifted relatively in the X-direction in the same manner, one chip row in the Y-direction can be drawn.
