Title: Pn junction diode for zener zapping
Inventor: NAGAYASU YOSHIHIKO
IPC: H01L21/822
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a Zener zapping p-n junction diode, having a characteristic of low breakdown voltage while having a high breakdown start voltage. SOLUTION: Boron(B) is diffused into an epitaxial layer 1 on a semiconductor substrate to form a p-type cathode layer 2. Phosphorus(P) or arsenic(As) is diffused to the surface side of the cathode layer 2 to form an n-type anode layer 3. Carrier concentration on the surface of the layer 3 is α. The layer 2 is formed as a thick diffusion layer having twice the thickness of the layer 3, so that surface carrier concentration β is sufficiently lower than the value of α. Since the cross section of a resistor is expanded in spite of the low carrier concentration of the layer 2, the internal resistance of the layer 2 can be reduced and the limited resistance value of the overall diode can be suppressed, attaining a Zener zaping p-n junction diode having a characteristic of low breakdown voltage while having a high breakdown start voltage.

Title: Data transferring control system
Inventor: YOKOYAMA KENICHI
IPC: G06F13/10
Filed: 1988-08-06
Abstract: PURPOSE:To shorten a transferring processing time by transferring dummy data with maximum transferring capacity when the remained dummy data of a specified byte number are written after data transferring is finished. CONSTITUTION:When the data are transferred from a channel 12, a gate 32 is turned on by a transferring stop deciding circuit 34 and the data are transferred to a device 4 by an oscillator 35 of a transferring speed. When a stop signal is sent by the channel 12, the gate 32 is turned off by the deciding circuit 34. However, since all the data parts of respective records in the device 4 are not always used for the transferring data, it is necessary to send the dummy data only for a remained data length which is shown on a counter 32c. At such a time, since the deciding circuit 34 switches the oscillator to a 35b so that a transferring clock can obtain a maximum transferring speed, the transferring time of the dummy data can be shortened.

Title: Method of detecting axial shift of diaphragm in electron beam irradiation system
Inventor: MIYAMORI AKIRA
IPC: H01J37/22
Filed: 1982-11-10
Abstract: PURPOSE:To accurately and easily detect axial shift by switching the focusing condition of an electron lens into two steps or more, line-scanning an electron beam on the specific area of a sample in the X or Y direction, detecting diffused electrons and x-rays, and plotting line profiles on a cathode-ray tube. CONSTITUTION:A switch is connected to a terminal (a) and a sample area B with an exceeding contrast is focused on a CRT screen. Then, the switch is changed over into a terminal (b) and excitation intensity is switched into two steps by the power supply 14 of an objective lens every horizontal scanning. In addition, the line-scanning is made on specific area B in the X direction indicated by a line L and a sample information signal is sent to the y deflector 13y of the cathode-ray tube and then a focal point profile P1 and a non-focal point profile P2 are displayed on the cathode-ray tube. When the axis of a diaphragm is aligned, both P1 and P2 appear in the center of the screen and the left and right skirts are intersected symmetrically. When the axis is not aligned, they are not intersected symmetrically. In this case, the axis must be aligned by actuating a drive mechanism 9. Furthermore, the axial alignment of the diaphragm in the Y direction is performed by changing the switch to a terminal (c).
