Title: Accumulation process for coating or filling reentry shape contact hole
Inventor: SHIEN SHIU
IPC: C23C14/35
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To enable the side wall of a hole to be completely coated with deposited material by a method wherein the material is deposited on the base of the hole smaller than a certain thickness required for filling up the hole, and the deposited material is reversely sputtered. SOLUTION: An Al target 14 and a substrate support platform 16 (substrate 18) are both biased at a negative voltage, and ions are impacted on the Al target 14 and the substrate 16 from plasma. Al atoms sputtered to the substrate 18 from the Al target 14 are deposited on the base of a re-entry shaped contact hole. On the other hand, Ar+ ions are made to re-sputter the Al material deposited on the base of the contact hole on the side wall of the re-entry shaped contact hole to coat. By this setup, a nucleus forming layer or a wet layer is formed on the surface of the side wall.

Title: Television receiving section having digital stage
Inventor: ZENKE MEERUGARUTO
IPC: H04N7/00
Filed: 1988-12-23
Abstract: PURPOSE: To easily adapt to different television standards by using a single A/D converter for an intermediate-frequency stage. CONSTITUTION: The signal of the intermediate-frequency stage (z) is converted by the single A/D converter aw, which is supplied with a clock signal (t) of approximately 20MHz in frequency, into a digital signal having frequency bandwidth approximately from about 1MHz to 9MHz. Therefore, only a single interface (s) is present between an analog and a digital signal processing circuit. Thus, adjustments to different television standards and their numerals are made only on the digital side of a signal processing network, so standard subordinate numerals are adjusted extremely easily as compared with an ordinary television image section where the adjustments should be made further partially on its analog signal processing network side.
