Title: Manufacture of semiconductor device
Inventor: KAYAMA SHIGEKI
IPC: H01L29/786
Filed: 1990-10-18
Abstract: PURPOSE:To obtain a good contact hole without influencing other parts by stopping an etching operation by using a newly formed semiconductor film when the contact hole is made in an oxide film by the etching operation by a method wherein another semiconductor film which is of a certain thickness or more is formed in a contact part constituting a semiconductor device. CONSTITUTION:A first semiconductor layer 12 used to form a channel region 23 is covered with an oxide film 16; the oxide film 16 is etched selectively; a contact hole 15 is made; and the semiconductor layer 12 is revealed in the following manner. That is to say, before the hole 15 is made, a second semiconductor layer 17 which is of a certain thickness is formed on the film 12 in parts other than the hole 15 to be made, and a gate oxide film 13 is formed here. After that, an etching operation is executed; the revealed film 12 is removed, and the contact hole 15 is made. Since the thick semiconductor layer 17 exists in other parts at this time, the film 12 is left as it is. Even when a third semiconductor layer 22 is applied onto the whole surface, it comes completely into contact with only the layer 12 inside the hole 15.

Title: Storing/retrieving method for relational data
Inventor: KAJI HIROYUKI
IPC: G06F17/27
Filed: 1989-10-27
Abstract: PURPOSE:To improve the retrieving efficiency of the relational data by providing a relational data file storing the relational data between elements and a filter which limits the access to the relational data and retrieving the relational data file only when this file passes through the filter. CONSTITUTION:A secondary storage device 2 is provided with a relational data file storing all information on the relational data. Then a filter is added to evade the useless accesses to the relational data file and stored in a main storage 3. When an element is designated and a retrieving request is produced to the relational data, the reference is given to a filter bit corresponding to a pair of elements. If the value of the filter bit is equal to '1', the relational data file is retrieved. Then the data file is not retrieved if the data bit is equal to '0' and the absence of the relational data is decided. Thus the retrieving efficiency is improved for the relational data file.
