摘要:
An EEPROM (Electrically Erasable Programmable Read Only Memory) has a structure in which the corners of a floating gate electrode of each memory cell MISFET near the source region thereof are rounded. The EEPROM is manufactured by a method characterized in that the ions of an impurity at a high dose are implanted in self-alignment with the floating gate electrode and control gate electrode of the memory cell MISFET so as to form the source and drain regions thereof, whereupon an oxidizing treatment is carried out.

A riding game system provides a feeling as if a player is riding on a real animal. The riding game system includes a mimetic animal device and a display showing a virtual space. The mimetic animal device is in the form of a horse having a head and a body. The player controls the mimetic animal device like controlling an animal in the virtual space by riding on the body, gripping a rein portion provided on the head and placing the player's foot on a pair of steps provided at the body. The head is inclined up and down and rotated from side to side. The body is rocked back and forth while the steps are also rocked back and forth. The rotational movement of the head from side to side and the rocking movement of the body backward and forward are detected as information for controlling the virtual horse in the virtual space.

A liquid crystal display device comprises: a liquid crystal display panel including a liquid crystal interposed between first and second transparent plates; a set of conductive lines disposed on a surface of at least one of said transparent plates; and a set of electrically conductive pads connected to respective first ends of the conductive lines. Each of the conductive lines has a lower layer made of aluminum or aluminum alloy and an upper layer made of a transparent conductive film. The aluminum or aluminum alloy layers in the conductive lines do not extend into any of the layers used to construct the pads. Each pad, instead, is formed of only a transparent conductive film. Additionally, the conductive lines have respective second ends which are commonly connected to a short-circuiting line. Disposed within the line is another electrically conductive pad, constructed in the fashion the pads in the aforementioned set are constructed. The pad in the short-circuiting line advantageously functions to receive test signals from a probe individually input into the pads at the first ends of the conductive lines. A user therefore can identify faulty conductive lines by determining whether test signals input into the pads at the first end of the lines are received at the pad in the short-circuiting line.

This invention discloses EEPROM which increases an erasing voltage V.sub.pp to be applied in a data write cycle by increasing an avalanche breakdown voltage between a source region and a semiconductor substrate in order to improve erasing efficiency, and employs a structure which strengthens the electric field at the edge of a drain region in order to let hot carrier be easily generated and to improve writing efficiency.

A semiconductor device includes at least two different elements having different functions. At least one of the elements is fixed within a recess provided in a substrate, and wirings are provided on an insulating film deposited commonly on the elements and the substrate, so that there is no step or clearance between the elements or between the element and the substrate, making it possible to easily form good interconnections.

In a calibration method a ring-shaped jig is disposed on a machine tool workpiece. The optical axis of a camera is aligned parallel to an axis of the machine tool. The jig is photographed with the horizontal or the vertical direction of the camera aligned with an axial direction other than the signal direction of the machine tool. The circumferential shape of the jig in the photograph is extracted as a contour. The center position of the jig in the image is calculated from the contour while all distortion correction coefficients in tangential and radial directions are ignored and set to zero. The displacements of the main point of the camera are set to zero. The translation distance, which is an external parameter of calibration, is calculated based on the center position of the jig in the image and the known three-dimensional center position of the jig.

An image capture system including two imaging systems of the same structure each having a wide-angle lens, which includes a front group, a reflection surface, and a rear group arranged in order from an object side, has a field angle larger than 180 degrees, and bends an optical axis of the front group toward the rear group by the reflection surface, and an imaging sensor, obtains an image in a solid angle of 4π radian by combining images imaged by the imaging systems. Each of the two wide-angle lenses includes the reflection surface between the front group and the rear group, the reflection surfaces are made to be common to the two imaging systems. This reduces an interval between lenses nearest to the object side in the front groups of the two wide-angle lenses, thereby reducing a distance between maximum field angles of the two wide-angle lenses.
