Title: Semiconductor integrated circuit with discrimination function
Inventor: SAITO MASATAKA
IPC: G01R31/28
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To discriminate many types of semiconductor integrated circuit using a small number of external terminals. SOLUTION: When a semiconductor integrated circuit having a specified function is measured for specified inspection terms, specified kinds of decision voltage VPP, VDL, VBLR and VPLT are outputted from external terminals at specified positions. Since the decision voltages VPP, VDL, VBLR and VPLT are generated from an internal circuit of the semiconductor integrated circuit and permutational combination thereof depends on the kind of product, the kind of product can be determined by measuring it. Consequently, erroneous application of measurement conditions or inspection criteria can be prevented without requiring any sealing. Permutational combination of the decision voltages VPP, VDL, VBLR and VPLT is preferably modified through modification of wiring pattern.

Title: Electron beam lithography apparatus
Inventor: OKI HIROBUMI
IPC: H01L21/027
Filed: 1988-03-25
Abstract: PURPOSE:To prevent an unexposed part of resist from being eroded by a developing solution, by providing a wafer coated with positive resist, means for applying an electron beam to a predetermined part of the wafer and a mechanism for supplying gas to a region over the wafer, the gas being excited by the electronic beam and chemically reacted with molecules constituting the positive resist. CONSTITUTION:O2 for example is supplied from an ashing gas supply mechanism to a region over a wafer 10 coated with a positive resist, whereby the O2 gas is adsorbed by the positive resist on the wafer. Electronic beam from an electron gun 3 is focused on the wafer by a focusing lens 5 and a predetermined place on the wafer 10 is scanned with the electron beam by a deflection signal generated by a deflection signal generating circuit based on a positional command from a control unit 8. Thereby, the O2 adsorbed in said place scanned with the electronic beam is excited by energy of the beam and combined with molecules constituting the resist. Thus, said place of the wafer is ashed and removed. Electrons scattered in the resist cause no ashing since such electrons will no encounter O2.

Title: Rolling method
Inventor: TSUKAMOTO EIHIKO
IPC: B21B1/22
Filed: 1983-04-25
Abstract: PURPOSE:To prevent a sheet material from producing a torsional deformation and to roll the material into a flat one by regulating the temperature distribution in the width direction of the material to be rolled to a specific one, in rolling the material by a roll cross mill. CONSTITUTION:A material A to be rolled is rolled by a roll cross mill, whose upper and lowr rolls constituted respectively of backup rolls 1, 3 and work rolls 2, 4 are slanted with respect to the advancing direction of the material A and are arranged to intersect with each other. In this case, the rolls 2, 4 can not bite the material A at the next stand or in reverse rolling because of the torsional deformation of material A caused by the mutually reverse offset directions of work rolls 2, 4 and by a shearing force between the material A and the rolls 2, 4. For preventing these troubles, the temperature distribution in the width direction of material A is made approximately uniform or the material A is partially heated or cooled so that the temperature of the central part is lower by about 20 deg.C than that of the end part, before rolling the material A by the roll cross mill.
