Title: Manufacture of semiconductor integrated circuit
Inventor: HARA YUJI
IPC: H01L21/76
Filed: 1985-10-21
Abstract: PURPOSE:To obtain a semiconductor integrated circuit having little bird's beaks and small surface steps by a method wherein insulatingly isolated element forming regions consisting of a single crystal silicon layer are formed on the semiconductor substrate utilizing a difference in oxidizing speed between the polycrystalline silicon layers and the single crystal silicon layer. CONSTITUTION:Silicon oxide films 2 are formed on a silicon substrate 1. Then, when silicon is deposited on the whole surface by an epitaxial growth method, a single crystal is silicon layer 4 and polycrystalline silicon layers 3 are respectively formed on the substrate 1 and the oxide films 2. Then, an oxidation is performed on the whole surface and a silicon oxide layer 5 is formed. At this time, with parts of the single crystal silicon layer 4a left on the substrate 1, the polycrystalline silicon layers 3 are all converted into silicon oxide layers. The silicon oxide layer 5 is etched by a wet or dry etching method and the surfaces of the single crystal silicon layers 4a left are exposed. At this time, silicon oxide layers 5a formed on the silicon oxide films 2 are formed into element isolation layers having small bird's beaks and the surfaces thereof become each a flattened one.

Title: Access control system for master/slave system
Inventor: MUTA TOSHIYUKI
IPC: G06F15/16
Filed: 1986-10-03
Abstract: PURPOSE:To perform conciliation even at time of write accessing, by providing a busy signal generation circuit in a slave, removing a busy signal first by a master at time of the write accessing, and issuing the busy signal from the salve to a common bus. CONSTITUTION:The slave, when detecting the write accessing by an address decoder, issues a timing signal WMS, and opens an AND gate 40. When a write strobe signal WSTRB is issued from the master, a J-KFF41 is inverted from an AND gate 40 by the inverted signal WSTRB. Thereby, a write state buffer 42 is turned ON, and the busy signal *BUSY of low level is outputted onto a busy line lb. Next, when a timing signal WAC is issued from the slave at a cycle before completing write, the FF41 is inverted, and thereby, the buffer 42 is turned OFF, and the signal *BUSY is removed as a high level. Therefore, at time of the write accessing, the busy signal of the slave is outputted following the turning OFF of the busy signal of the master, and it is turned OFF one cycle before the completion of the write.
