Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To save working man-hours by providing a specific termination circuit to release troublesome works at a remotest receiver from a video transmitter or a final termination of a transmission line at a site. SOLUTION: Other circuits 200-203 than a termination circuit 123 of a receiver 120 are referred to as an internal circuit that is connected between line connection terminals 121, 122 in parallel with the circuit 123. The input impedance of the internal circuit is selected to be a high impedance not giving effect on a transmission line 100 in comparison with a characteristic impedance of the line 100. Thus, the line 100 connected between the line connection terminals 121, 122 when a changeover switch 124 is closed is terminated with an impedance nearly equal to its characteristic impedance. When the switch 124 is open, the line 100 connected between the line connection terminals 121, 122 is terminated with a higher impedance than the characteristic impedance. Thus, the termination of the transmission line is not required in the case of mount of a video intercom.

Title: Formation of diffused well
Inventor: HAYAMA HIROSHI
IPC: H01L21/8238
Filed: 1987-04-30
Abstract: PURPOSE:To produce a device having a strong resistance to the parasitic bi-polar phenomenon by forming on a p-type Si substrate an n-type region into which P and As or P and Sb have been introduced, depositing a p-type epitaxial layer on the substrate, and thermally diffusing P and As or P and Sb from the n-type region into the p-type epitaxial layer. CONSTITUTION:Introduced into a p-type substrate 1 are, for instance, P and As, thereby to form an n-type region 2, and thereon a p-type epitaxial layer 3 is deposited. And by diffusing P and As from the region 2 into the layer 3, an n-type diffused well 4 is formed. Thus, a well can be formed at the substrate 1 surface side, and since As which has been introduced simultaneously with P has a small diffusion constant as compared with P, it does not largely move and can be made to stay at the interface of the substrate 1 and the layer 3. Therefore, an n-type diffusion well is formed which has a high-concentration impurity region 5 at the interface of the substrate 1 and the layer 3 and has such an impurity distribution as having a low impurity density at the surface.
