Title: Photoelectron transferring and manufacture thereof
Inventor: SAKAMOTO JUICHI
IPC: G03F1/00
Filed: 1986-12-19
Abstract: PURPOSE:To continuously irradiate many photoelectrons by forming a predetermined pattern on a light permeable substrate using electrically conductive film, covering the film and the substrate not provided with the film with specific photoelectric film, thereby irradiating light which can be generally obtained. CONSTITUTION:A light output from a light source which can be generally obtained, irradiated from above a photoelectron transferring mask 2 is transmitted through a transparent quartz substrate 21 to be irradiated to the rear side of a metal film 22 or a CsSb film 23 formed on the substrate 21. When this light is irradiated to the rear surface of the film 23, the film 23 irradiates photoelectrons. Since the film 23 is formed by a predetermined pattern with the film 22, the photoelectrons are irradiated only from the part covered with the film 23 directly on the substrate 21, and the film 23 of the section covered through the film 22 does not irradiate the photoelectrons. Thus, a predetermined pattern image formed on the mask by the transmitted light irradiated from above the mask 2 is transferred to the sample to be aligned, such as a wafer.

Title: Testing method for charge transfer element
Inventor: KOYA NOBUYUKI
IPC: H04N5/335
Filed: 1986-12-18
Abstract: PURPOSE:To decide whether or not there is a charge leak in a transfer part by transferring a constant amount of charges, stopping the transfer for a constant period and restarting the transfer, and checking the quantity of variation in output voltage at this time. CONSTITUTION:Voltages VDD=-15V, VGG=-14V, and GND=0V are applied previously. When clock input is stopped for a certain period, the storage amount of charges varies in the period if there is a leak in a charge transfer area and when a clock is operated again, the output voltage of the stage where the charge leak occurs varies. A figure shows the output waveform when there is the charge leak in a 4093th charge transfer stage. An output voltage V02' with a voltage difference DELTAV is generated for a normal output voltage V02. An actual defective has charge leaks in many stages and it takes a long time to measure the charge leaks of the respective charge transfer stages, so the 4097 stages are divided by 20 and the stage where the largest leak occurs is sampled.
