Title: Ad converter
Inventor: HOSOYA SHIRO
IPC: H03M1/14
Filed: 1987-10-19
Abstract: PURPOSE:To contrive to reduce manufacture cost by using a voltage comparator used for the 1st parallel AD conversion processing deciding a high-order bit of a digital output in common for the 2nd parallel AD conversion processing deciding a low-order bit of the digital output. CONSTITUTION:Three-input 2-output voltage comparators C1-C3 are used for both the 1st and 2nd parallel AD conversion processing. Thus, number of voltage comparators is halved regardless of the provision of the same performance as a conventional serial/parallel AD converter and the chip size is much reduced. Number of elements of the voltage comparator in use is more than that of the voltage comparator used for a conventional AD converter, but in considering that much of the layout area of the voltage comparator is used by the coupling capacitor, the increase in number of elements does not disturb the reduction in the chip size. Thus, the manufacture cost is reduced.

Title: Charged particle beam lithography
Inventor: ASARI TOSHIHIRO
IPC: H01L21/027
Filed: 1986-11-07
Abstract: PURPOSE:To shorten the pattern delineating time by making the charged particle beam diameter and the charged particle beam current amount at the time of hardening the mark's perimeter including the mark larger than the charged particle beam diameter and the charged particle beam current amount at the time of detecting the mark position and delineating a pattern. CONSTITUTION:The diameter (cross-sectional area) of the charged particle beam at the time of hardening a resist 2 on the mark's perimeter including a mark M is made fairly larger than the diameter (cross-sectional area) of a charged particle beam EB which is used when detecting the mark M and delineating a pattern, and the beam current is also made large to prevent the beam current density from reducing by an amount corresponding to the increase of the diameter (cross-sectional area). With this, hardening of the resist on the mark's perimeter including the mark can be performed in an extremely short time. Accordingly, the time required for the entire lithographic process can be shortened considerably.
