Title: Method for sweeping oscilloscope
Inventor: PATORISHIA EI DASOOTERUSU
IPC: G01R13/20
Filed: 1987-11-09
Abstract: PURPOSE:To specify the shortest leading time of a digital oscilloscope by omitting unnecessary recording sweeps and executing a display routine which requires a long time only once by an irreducible minimum number of recording sweeps. CONSTITUTION:The sweep time range of the oscilloscope is determined and divided by the number of time backets. When the quotient is <=1/2 as large as the leading time specification TR, a minimum sweep variation determined according to a leading time criterion to determine a variable value by using a binominal probability formula, a counted value is initialized to 0 and increase by making a recording sweep, and addition is carried out up to the minimum number of sweeps. When the quotient is larger than 1/2 the leading time specification, a minimum sweep variable determined by a full percentage criterion is used and a recording sweep is made similarly. An input signal 35 is extracted and then A/D-converted 80, stored 90, and displayed 10 and the control over those operations and calculation processing are performed by a control circuit. Consequently, the oscilloscope which makes random repetitive sweeps are put in sweeping operation efficiently.

Title: Manufacture of mos semiconductor device
Inventor: OSANAI JUN
IPC: H01L21/28
Filed: 1988-11-09
Abstract: PURPOSE:To prevent development of peeling and spikes of metal silicide of high melting point as a contact section by applying a process to eliminate metal silicide of high melding point at a contact section and a process to introduce impurity ions from an opened contact hole. CONSTITUTION:When a contact is opened, excessive etching is performed to also eliminate metal silicide 5b of high melting point at a contact hole. At this time, etching proceeds also at a silicon substrate 1 and diffusion layer junction becomes shallow. Therefore, if a wiring metal 8 is applied to enable alloying reaction, spike develops. Impurity is introduced from a contact hole and a diffusion layer 3d of the contact section is selectively made rather deep to avoid spike. Peeling and spikes of metal silicide of high melting point which develop during contact hole glass flow can be thereby prevented.
