Title: Semiconductor device provided with thin film resistor
Inventor: TAKASU HIROAKI
IPC: H01L29/43
Filed: 1989-07-10
Abstract: PURPOSE:To prevent erasure of a thin film resistor by overetching in an etching of an insulating film on the resistor for directly connecting the resistor to aluminum of wirings by electrically connecting the resistor to the aluminum through a high concentration impurity diffused layer. CONSTITUTION:A connection of a thin film resistor 2 to aluminum 4 of wirings is formed in a structure formed through a high concentration N-type diffused layer 12. A P-type silicon substrate 11 is isolated by the layer 12. Since the resistance values of an element isolating insulating film 13 and the resistor 2 are high such as several hundreds kOMEGA or more and the contact resistance between an aluminum diffused layer and the resistor is about several tens ohms, the whole resistance value becomes the same as that of the resistor. Thus, a high resistance element can be manufactured with high controllability by patterning the resistor 2.

IPC: H04L1/00
Filed: 1993-07-22
Abstract: PURPOSE: To provide a LAN management function for monitoring and managing errors on physical links coupling LAN stations with each other. CONSTITUTION: A LAN management device partially incorporates a function- intensified link error monitor(LEM) 301. The LEM 301 discriminates the predicted value of a link error rate(LER) which is calculated as a function of time and a function-intensified LEM 301 discriminates the adjusted predicted value of the LER by applying a characteristic function peculiar to a link to the predicted value of the LER. The characteristic function peculiar to the link is used for changing the responsiveness of a station to the errors by taking the specific characteristic of a link in which an error occurs and the adjusted predicted value of the LER is compared with an alarm threshold and a cut-off threshold for discriminating the measure to be taken for the erroneous link.
