摘要:
A method of manufacturing a semiconductor device including an integrated circuit part in which an integrated circuit is formed and a main wall part including metal films surrounding said integrated circuit part, includes the step of selectively forming a sub-wall part including metal films between the integrated circuit part and the main wall part, in parallel to formation of the integrated circuit part and the main wall part. A sub-wall part which is in an “L” shape is provided between each corner of the main wall part and the integrated circuit part of the resulting semiconductor device.
摘要:
A main wall part is provided so as to surround an integrated circuit part. A sub-wall part which is in “L” shape is provided between each corner of the main wall part and the integrated circuit part. Therefore, even if the stress is concentrated due to heat treatment or the like, the stress is dispersed to the main wall part and the sub-wall part, and hence peeling between layers and a crack are unlikely to occur, as compared with the conventional art. Further, even if the crack and the like occur at the corner, moisture from the outside hardly reaches the integrated circuit part when the main wall part and the sub-wall part are coupled to each other. For this reason, it is possible to ensure an extremely high moisture resistance.

A device for preventing a thin apparatus from overturning by fixing it with a fixing portion of a desk. The device prevents overturn of the thin apparatus, which is a tower type computer, or the like, as the apparatus is fixed to an overhanging part of the desk using a fixture which is a combination of a hook and a U-shaped bracket, when the thin apparatus is disposed in dead space at the back of, the side of, or under the desk.

A semiconductor device includes a test target circuit; scan chains that enable scanning of the test target circuit; a first random number generation circuit that forms test patterns supplied to the scan chains; a second random number generation circuit that is provided separately from the first random number generation circuit; and a random number control circuit that uses the random numbers generated by the second random number generation circuit to change the random numbers generated by the first random number generation circuit. In a test of the semiconductor device, since a period of a clock of a scan chain does not need to be longer than that of a clock of a pattern generator, the number of clocks of the pattern generator needed for a test can be prevented from increasing. Accordingly, a test time can be prevented from increasing.

In an electronic apparatus including an electronic circuit device, a board and a control circuit device for controlling the electronic circuit device, a socket for mounting the electronic circuit device is mounted on the board. The socket incorporates a switch for electrically connecting the control circuit device to a reference voltage line when the electronic circuit device is not mounted in the socket and electrically connecting the control circuit device to the electronic circuit device when the electronic circuit device is mounted in the socket.
摘要:
A delay time verifier to verify the delay time for a logic circuit using a time verification model prepared according to the graph theory. It comprises a verified model information file to store in advance the delay time verification information for each of the arcs in the time verification model including delay time for each rise/fall type of the signal at the start point node and the end point node of the arc, an invalidness specifier to specify an arc with invalid data and rise or fall of the signal to be invalidated for the arcs where only one of rise and fall signals is allowed to be valid, a modifier to modify the delay time verification information stored in the file so that the information for the arcs whose rise or fall signal specified by the invalidness specifier becomes invalid is modified, and a delay time verifier to verify the delay time of the logic circuit based on the delay time verification information after modification by the modifier.
