Title: Method for evaluating silicon wafer by fe-b concentration measurement
Inventor: KATO HIROTAKA
IPC: G01R31/26
Filed: 1994-08-24
Abstract: PURPOSE: To realize an accurate measurement of Fe-B concentration by comparing the value of a specific relation of minority carrier diffusion length before and after activation of a p-type silicon wafer with a predetermined value obtained from a specific correlation graph thereby making a selection between presence and absence of oxygen deposition. CONSTITUTION: The minority carrier diffusion length is measured for a silicon wafer where the Fe-B is bonded at Step 1 and the value Lb is stored. The minority carrier diffusion length is then measured under dissociated state at Step 2 and the value La is stored. The operation result (Lb-La) /Lb is compared with a constant C at Step 5 and if (Lb-La) /Lb<C, the operation is shifted to Step 6 where the operation of Fe-B concentration for the wafer is interrupted before the operation returns back to Step 1. A decision is then made than the wafer has an oxygen deposition defect and the wafer is separated. The constant C is determined from the correlation graph of Lb and Lb-La according to a formula; C= (Lb-La) /Lb. This method realizes an accurate measurement of Fe-B concentration.

Inventor: HIROSE MINORU
IPC: G03F7/20
Filed: 1986-09-20
Abstract: PURPOSE:To keep the variation of a reduction ratio approximately constant by providing a reducing lens system reducing exposure beams passing through a reticle and projecting the original picture pattern of the reticle onto a wafer with a means for temperature control approximately proportional to the change of atmospheric pressure. CONSTITUTION:Exposure beams emitted from a light source 1 are transmitted through a reticle 3, and projected to a reducing lens system 4. The reducing lens system 4 consists of a plurality of reducing lenses, etc., and is housed in a box body 5, a gas (temperature control air) for temperature control such as He, N2, etc. is flowed in paths formed outside the box body 5, and the temper ature of the gas is changed in proportional to the value of a barometer fitted at an arbitrary position on the inside or outside of an optical exposure device. The temperature of temperature control air increases and the temperature of the reducing lens system 4 in the box body 5 is elevated when atmospheric pressure rises, and said temperature declines and the temperature of the reducing lens system 4 is lowered when atmospheric pressure drops. Accordingly, the refractive index of the reducing lens system in the box body 5 is kept approxi mately constant regardless of the change of atmospheric pressure.

Title: Semiconductor device
Inventor: NISHIMAKI TATSUO
IPC: G11C17/18
Filed: 1991-09-03
Abstract: PURPOSE:To prevent the drop of a potential due to a leak by adding a capacity to a charge holding part at the time of detecting the drop of the potential due to the leak, in a semiconductor device having a read only memory of a precharge type. CONSTITUTION:The drop of the potential of a charge holding part 5 is generated due to the leak of the charge, when the leak of a transistor is increased under a high temperature state, or when the transistor is operated by a low speed clock. When the drop of the potential is judged by a potential judging device 10, a capacity addition switch 11 is operated in order to add an additional capacity 12 to the charge holding part 5. Thus, the drop of the potential due to the leak can be suppressed by adding the capacity to the charge holding part 5, and increasing the total charge amounts which can be charged in the charge holding part.

Title: Video tape recorder
Inventor: IKATA KOICHI
IPC: H04N9/80
Filed: 1990-08-23
Abstract: PURPOSE:To secure the band of a chrominance signal and to expand the band on a luminance signal by recording a voice signal compressed with time base and the chrominance signal on the depth of a magnetic tape. CONSTITUTION:A Y/C separator 2 separates the luminance signal from the chrominance signal, and the respective signals are supplied to a luminance signal recording processing circuit 3 and a chrominance signal recording processing circuit 4. Time base compression circuits 10 and 11 compress the voice signal inputted based on the gate signal supplied from a gate circuit 7 with time base. In this case, the voice signal is compressed on the time base to be deeply recorded on a track for signal recording along with the chrominance signal, and the luminance signal is to be recorded on it. At the time of the reading of the signal, the luminance signal is reproduced, and the chrominance signal and the voice signal compressed with time base are separated based on the separated synchronizing signal, and the signal is reproduced by expanding the voice signal with time base. Thus, the chrominance signal band can be remarkably expanded without narrowing the band of the luminance signal.

Title: Dynamic ram
Inventor: NAGASHIMA YASUSHI
IPC: G11C11/409
Filed: 1994-09-19
Abstract: PURPOSE:To prohibit output buffer operation independently of a write enable signal by supplying a multiplexed address signal through a timing identification circuit and supplying the write enable signal faster than an address stroke signal in a DRAM of a static column system. CONSTITUTION:The change timing of the write enable signal WE is identified by a timing control circuit TC based on the change timing of a column address strobe signal CAS, and the operation of a data output buffer DOB is controlled. Thus, two kinds of write operation modes are realized, and terminals Din, Dout are connected to respective external data buses and used. By such a constitution, a use of a RAM is enlarged, and further, since the continuous write/read of the characteristic of the RAM of the static column system is enabled, a memory function is improved. Further, since a timing relation between the CAS signal and the WE signal is identified, these effects are realized only by adding a remarkably simple circuit.
