Abstract: PURPOSE:To increase the insulating property between layers of a multilayer interconnection, by oxidizing a part of a first conductive layer after the first conductive layer is formed on a substrate on which elements are formed, and by forming a second insulating layer and a second conductive layer thereon. CONSTITUTION:On a silicon substrate 1 on which a semiconductor element is formed, a metal layer 3 of aluminum is formed via a silicon oxide film 2. A first insulating film 4 is formed by oxidizing a part of the surface of the layer 3. Resist is spread on the whole surface of the layer 4, and the layer 3 is eliminated by photolithography leaving a pattern of the first conductive layer. After the resist is eliminated, a second insulating layer 7 is deposited on the substrate 1 via the film 2 containing the pattern 3. After the layer 7 is made flat, an insulating layer 9 between conductive layers is formed, and a contact hole 10 is made. Then a second conductive layer 11 is formed.

Title: Establishing method for data link
Inventor: SUZUKI KAZUYOSHI
Filed: 1986-11-26
Abstract: PURPOSE:To establish next new data link during the establishing of data link between a master station and a slave station by returning the reply from the slave station to the master station with respect to polling information. CONSTITUTION:When the master station transfers a data to a slave station T1, the master station sends polling information to other slave stations (T2, T3) in succession to the data information transmission. Suppose that a transmission request takes place in the slave station T3, the slave station T3 receiving the polling information from the master station returns the reply to the polling information to the master station. The master station receiving the response gives transmission permission to the slave station T3. On the other hand, the slave station T1 receiving the data returns the reception acknowledge of reception enable or reception disable to the master station. Then the master station receives the reception acknowledge. The reception acknowledge is received after the response to the polling information is received because of the difference in the processing speed of the data information and polling information. Thus, while the reception acknowledge to the data transfer is awaited, the acknowledge of polling information is received to select the slave station establishing the data link next.
