Title: Method for depositing thin film and thin film
Inventor: BILARGE SADESAI
IPC: C23C14/35
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a laminated thin film capable of precisely controlling the film thickness or the compsn. SOLUTION: A uniform compd. target 21 composed of >= two materials is used, the magnetic field is periodically changed, and the depositing rate of one material is periodically increased to that of the other material. The change of the magnetic field changes the magnetic field sweep time and changes the thickness of the deposition layer. In this case, the layer thickness is inversely proportioned to the magnetic field sweep time. Or, the magnetic intensity is changed to change the relative compsn. of sputter seed. In an electromagnet, it is executed by controlling the amplitude of the waveform of the input current, i.e., the maximum current.

Abstract: PURPOSE:To reduce the variance of working, by sharing the capacity of a dummy memory cell with plural data lines and increasing the occupied area of the capacity. CONSTITUTION:The operation of a semiconductor memory device incorporating a main dummy cell DC is exactly same as the working waveform of a conventional device. In other words, data lines 4 and 4' are previously precharged to high potentials (power supply voltage VCC), and therefore penetration preventing MOSTs 17n and 17n+1 having gates connected to the lines 4 and 4' are turned on. Therefore if a dummy word line 6' is set at a high potential by a driving pulse phi'DW, selecting switches MOSTs 10n and 10n+1 connected to the line 6' are turned on. Then data lines 4'n and 4'n+1, and capacities CDC' and 8' are conduction state. In this case, reference signal voltage VD generated on the lines 4'n and 4'n+1 is set at 1/2 signal potential difference V1-0 read out of the memory cell. Thus it is possible to apply desired reference voltage.
