Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To remove obstacle during metallic wiring formation by reducing an unnecessary sidewall film on an isolation film generated by division formation of a gate electrode. SOLUTION: A height h2 of a gate electrode 11 on an isolation film 6 is made smaller than a height h1 of the gate electrode 11 on an element formation region by leaving a first silicon layer 3 in an element formation region without removing it. Since the gate electrode 11 on an element formation region comprises a lamination film of first and second silicon layers 3, 8 and a WSix film 9, and the gate electrode 11 on the isolation film 6 comprises the first silicon layer 3 and the WSix film 9, resulting in the relation h2<h1. Therefore, it is possible to make a sidewall film 14 on the isolation film 6 small during formation of a sidewall spacer film 13 of an N-channel transistor.

Title: Integrated circuit for driving thermal head
Inventor: KANAKUBO YOSHIHIDE
IPC: B41J2/35
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To restrict an increase in circuit size even when printing with a plurality of gradations or in a plurality of colors is carried out by one heating resistor. SOLUTION: Two latch circuits 5r and 5b for red and black are used for two-color printing data. One shift register 4 is used in common for inputs of a red data r and a black data b to supply data to the latch circuits 5r and 5b. Since the shift register 4 is shared, one shift register 4 will do for two-color printing and a chip can be made small. In using the integrated circuit for driving a thermal head, inputs of the read data r and black data b are alternately input from a control terminal SI and a corresponding latch signal is input after 64 bits of each color data are completely input, thereby enabling two-color printing (setting).

Namely, in the case of focusing in the area b3, a focus detection area where focusing display should be performed is the range of two areas centering around the area b3. The focus detection area in the focusing state within the range is eight areas b3, b5, c2, CM, c6, d1, d3 and d5. By performing such focusing display, a situation that needless focusing display is performed to hinder photographing is prevented. There is no anxiety that a user recognizes as if an erroneous subject were brought into focus.
