Title: Electrostatic protective element for semiconductor device
Inventor: SAWAIRI AKIHIRO
IPC: H01L27/04
Filed: 1989-07-05
Abstract: PURPOSE:To improve input/output characteristic without increasing the parasitic capacity of a diode by varying the minimum intervals between first, second diodes and a reverse conductivity type buried layer, a one conductivity type inversion preventive region. CONSTITUTION:The minimum interval between the P-type inversion preventive region 2 around a first diode and a N-type first buried layer 3 is reduced, and a reverse voltage resistance of a junction between both regions is reduced to be smaller than that of the first diode. Thus, if a discharge occurs from a high potential power source wiring 12 side to input/output signal wiring 11 side, a current flows from the layer 3 through a P-type silicon substrate 1 and a N-type second buried layer 4 at a lower voltage than that in which a current flows from a N-type first region 6a through a P-type second region 9a. Thus, a voltage between the wiring 12 and the wiring 11 can be suppressed to that lower than a conventional one to suppress breakdown or deterioration of an inner element. Thus, high speed and high reliability of a semiconductor device can be compatible without increasing a parasitic capacity of input/output terminals.

Filed: 1981-10-31
Abstract: PURPOSE:To permit annealing in a magnetic field with good efficiency by a method wherein an exciting coil for generating the magnetic field is provided at the outside of a furnace and a DC magnetic field is introduced in the furnace. CONSTITUTION:A magnetic core 6 forms a magnetic circuit by working with an amorphous magnetic iron core 1 installed in an annealing furnace 5 and a part of the magnetic core 6 is exposed to the outside of the annealing furnace 5. An exciting coil 2 is wound on the part of the exposed magnetic core 6. A switch 4 is turned on under the condition that the temperature of the annealing furnace 5 is maintained at a suitable annealing temperature and an iron core 1 is magnetized. Next, the switch 4 is turned off under this condition and the annealing in the magnetic field of the iron core 1 is done. In this way, the exciting coil is not directly wound on the iron core 1, so working hours can be shortened and the exciting coil is installed at the outside of the furnace. Therefore, the application of heat-resistant treatment is not required for the exciting coil. This can efficiently perform annealing in the magnetic field.
