IPC: H01L29/84
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To prevent the breakdown of an intermediate oxide film and make reducible the number of the anodic joinings of first and second glass caps to the SOI wafer for forming the sensor chips and make possible the simplification of processes and the contraction of an assembling time. SOLUTION: An SOI wafer comprising a supporting layer 1a, an intermediate oxide film 1b, and an active layer 1c is used as a wafer for forming acceleration sensor chips. The portion of the intermediate oxide film 1b which is extruded to the outer periphery of the SOI wafer is removed therefrom to connect electrically the supporting layer 1a with the active layer 1c by a metallic thin film 10. While interposing an acceleration wafer W13 between upper and lower glass caps 2, 3, the intermediate product is set on a grounded heating plate 100. After contacting a positive electrode pin 101 with the metallic thin film 10 and contacting a grounded electrode pin 102 with the upper glass cap 2, a voltage of about 600-1000 V is applied to the electrode pin 101.  Thereby, while preventing the breakdown of the intermediate oxide film 1b, the anodic joinings of the upper and lower glass caps 2, 3 to the SOI wafer for forming the acceleration sensor chips are made possible to make reducible the number of the anodic joinings.

Title: Small-sized laser
Inventor: TODORI KENJI
IPC: G02B5/18
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive, high speed and small-sized wavelength laser by using a photonic crystal formed by a grating in place of a resonator mirror. SOLUTION: A photonic crystal formed by a grating in place of a resonator mirror is used. Synchronization with exciting light is not executed in a stage wherein dye laser beams of picosecond or femtosecond order pulses are generated, and resonance is repeated within the time of one pulse width. For this reason, a resonator length should be set shorter than the distance wherein light advances in picoseconds or femtoseconds. Thereupon, a laser medium containing material 4 is held with two diffraction gratings which face across a distance within 1 mm, or one mirror and one diffraction grating which face across a distance within 1 mm and excited with a laser 2. For example, excitation with laser 2 can easily be realized by using photonic crystals using the grating as the mirror.  Consequently, even if synchronization with the exciting light is not satisfied, high speed dye laser oscillation can be obtained, and the device can be miniaturized.

Title: Substrate for electro-optical device, electro-optical device, driving method therefor, and electronic equipment, and projection type display device
Inventor: KATAYAMA SHIGENORI
IPC: H01L29/786
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To improve reliability by controlling deterioration in a withstand voltage of a transistor due to surplus carriers by electrically connecting a semiconductor layer as a channel area with a scanning signal line different from a scanning signal line with which a gate electrode of a transistor is electrically connected. SOLUTION: A channel 6B of a transistor of which the gate is connected with a scanning signal line 8A (Xn) is electrically connected with the precedent scanning signal line 8A (Xn-1). In this precedent scanning signal line 8A (Xn-1), a non-selection potential of which the selection period has already been finished and is in non-selection period is at a lower potential than the lowest potential of an image signal, therefore, electric charges accumulated in the channel 6B are made to flow into the scanning signal line 8A (Xn-1) of the precedent stage. Thus, the channel area of each transistor is electrically connected with the scanning line of the adjacent precedent stage, and suppresses a substrate floating effect by pulling out the surplus carriers accumulated from the cannel area into the scanning signal line.

Filed: 1990-12-27
Abstract: PURPOSE:To prevent breakage of a lateral MOS field-effect transistor due to surge voltage by providing a second main surface of a semiconductor substrate with a region of same conductivity type as said semiconductor substrate having high concentration. CONSTITUTION:An extention drain region 1 is formed while extending up to the bottom of a drain bonding pad, one or more drain contact regions 2 are formed on the whole region of said surface, a drain electrode 3 electrically connected to those drain contact regions 2 and a region 4 having low resistance and same conductivity type as a semiconductor substrate 11 are connected on the rear of the semiconductor substrate 11. When surge voltage is impressed between the drain electrode 3 and the source electrode 19, parasitic capacity between the extention drain region 1 and the semiconductor substrate 11 is increased so that the surge voltage is not impressed as it is but impressed with lowered amplitude. Further, since the region 4 having low resistance is provided on the rear of the semiconductor substrate 11 having high resistance, surge voltage goes through region 4 of low resistance on the rear of the semiconductor substrate 11.
