Title: Ion beam accumulation
Inventor: FURUMURA YUUJI
IPC: H01L21/285
Filed: 1981-06-29
Abstract: PURPOSE:To form a low-doped semiconductor crystal layer having a few crystal defect by performing sputter milling before an ion beam accumulation process. CONSTITUTION:Prior to an ion beam accumulation process, ion beams 2 provided with energy generating sputter milling effect are aimed at the surface of a substrate 1 and the removal of sputter milling is applied to the impurities 3 existing on the shallow surface of the substrate 1 and those 4 adhered to the surface. After washing the surface of the substrate, the temperature of the substrate 1 is successively raised up to a temperature suitable for accumulation and then the voltage used for the sputter milling process is gradually decreased and the energy of the ion beams 2 is reduced without exposing the substrate in air to perform a process for ion beam accumulation on the substrate 1. This forms a layer with high purity and good insulating dielectric strength.

Filed: 1986-04-30
Abstract: PURPOSE:To make movement of a bonnet preventable without fail, by installing a bonnet rear movement preventing device consisting of a stopper and a hook, and interlocking the engaging state release with the release operation of a bonnet lock member. CONSTITUTION:When a vehicle comes into a head-on collision against another vehicular or the like, the front of a vehicular body A is subjected to buckling deformation and a bonnet 4 gets moving the rearward, a hook 2a of the bonnet movement preventing device 2 engaged with a stopper 2b turns round centering on a short shaft 2d of a support member 2c at the side of the vehicular body A whereby the engagement does not come off, thus the bonnet 4 is bent from an almost central part, preventing it surely from penetrating into a vehicular room. And, when the vehicle is bumped from the side too, the stopper 2b and the hook 2a are always engaged with each other so that the bonnet 4 is in no case floated up. When this bonnet movement preventing device 2 unlocks a bonnet lock member with operation of an opener lever inside he vehicular room at time of bonnet opening, it interlocks with this release, so, the engagement between the stopper 2b and the hook 2a is released as well. Thus bonnet movement is surely prevented from occurring.

IPC: H04N5/335
Filed: 1985-05-15
Abstract: PURPOSE:To form a sufficiently deep impurity region, to inhibit the increase of photosensitibity and to augment density by shaping a deep groove around a photodiode and isolating the phototdiode from a charge transfer section and other photodiodes. CONSTITUTION:Deep grooves 9 formed by etching and processing the surface of a substrate 1 are shaped around photodiodes 2, and the photodiodes 2 are isolated from charge transfer sections 3, and also isolated from other photodiodes and other charge transfer sections 3A. The inside of a deep groove 9b isolating the photodiode 2 from the charge transfer section 3 is filled with a conductive material such as polysilicon, thus constituting a signal reading electrode 4. Since an N-type region 5 in the photodiode 2 is isolated from others by the deep grooves 9, a diffusion in the horizontal direction is inhibited by the deep grooves 9 even when the thermal diffusion of the N-type region 5 is conducted for a prolonged time, and a diffusion is progressed only in the depth direction. Accordingly, the depth of the N-type region 5 can be increased sufficiently, and photosensitivity can be improved.
