Title: Semiconductor device
IPC: H01L23/522
Filed: 1992-11-20
Abstract: PURPOSE:To obtain an excellent ohmic contact by combining a BPSG insulation film with a titanium nitrifying film-made barrier metal. CONSTITUTION:A silicon oxide film 4 (BPSG) containing B and P is laid out on a silicon board 1 as an insulation film where a first metal film 5 containing a titanium nitriding film and an Al alloy-made second metal film 6 containing Si are laid out thereon. The first metal film 5 and the second metal film 6 are electrically connected to an impurity diffusion layer 2 formed on the board 1 by way of a contact hole 7 formed on the BPSG film 4. At that time, the first metal film 5 prevents the B contained in the BPSG film form diffusing into the second metal film 6 and the silicon contained in the second metal film 6 from selectively solid-state epitaxially growing on the surface of the board 1 on the bottom of a control hole 7. This construction make it possible to produce an excellent ohmic contact, flattening the surface of a circuit.

Title: Semiconductor substrate
Inventor: KOURA SETSUKO
IPC: H01L23/14
Filed: 1991-10-30
Abstract: PURPOSE:To obtain a substrate for mounting semiconductor elements on which a ceramic insulating layer can be formed with excellent adhesion and which has an excellent heat radiating characteristic. CONSTITUTION:After an Al layer is formed on the surface of a metallic substrate having a coefficient of thermal expansion which is nearly equal to that of a semiconductor element by an electroplating method, an anodic oxide film is formed on the surface of the electroplated Al layer by anodic treatment. The anodic oxide film is used as the base of a ceramic insulating layer. Since the affinity between the anodic oxide film and ceramic material used for the insulating layer is high, the adhesion between the insulating layer and oxide film is high. In addition, since the anodic oxide film itself works as an insulator, the thickness of the ceramic insulating layer can be reduced and the heat radiating characteristic of the semiconductor element can be improved.

Title: Acoustic position measuring method
Inventor: TAKAHASHI HIDEYUKI
IPC: G01S5/28
Filed: 1989-12-01
Abstract: PURPOSE:To take an accurate measurement even when a position measurement rate is increased by controlling a reception gate by using a slant range calculated from the depth of a sound source and a 1st azimuth angle so that each receiver receives only a wave matching transmission timing. CONSTITUTION:A depth sensor 9 fitted to a sounding device 1 measures the depth D and the slant range (r) and a propagation time tD are calculated 6 from the azimuth angle theta obtained by SSBL receivers 51 - 53 and the depth D. A gate time G is found and set by using the time tD so that respective switch circuits 11 - 13 are opened matching arrival timing points E1 - E3 when period-T pulses which are sent at respective timing points T1 - T3 arrive at a receiver array 2. Consequently, when a sound wave which is sent at the timing T1 reaches the array 2 at the timing E1 the time t1 later, the gate of a circuit 11 is opened at the time intervals tD before and after the time t1 and the received signal is sent to the receiver 51. Similarly, the receivers 52 and 53 receive signals after times t2 and t3. Consequently, received waves can be separated from one another and even when the position measurement rate is increased, an accurate measurement is taken.
