Title: Method for evaluating cleaning of semiconductor wafer, and manufacture of semiconductor device
Inventor: SUZUKI YOSHINORI
IPC: G01N21/00
Filed: 1994-03-04
Abstract: PURPOSE:To measure a sulfide residue in a short time with a good sensing accuracy, by removing the natural-oxide film present on either surface or rear surface of a semiconductor wafer therefrom through the dry-etching using a hydrofluoric-acid vapor, and thereafter, by determining the sulfide left on either surface or rear surface of the semiconductor wafer through a Fourier-transform infrared spectroscopy. CONSTITUTION:A diluted aqueous hydrofluoric-acid solution 1 is filled into a cylindrical Teflon vessel 3 having a somewhat smaller size than a wafer 2, and the vessel 3 is covered with the wafer 2 while its rear surface is turned downward. Then, the natural-oxide film present on the surface or rear surface of the wafer 2 is removed therefrom while it is dry-etched by a hydrofluoric-acid vapor. Thereafter, the sulfide left on either surface or rear surface of the wafer 2 is measured by a Fourier-transform infrared spectroscopy and it is determined. Thereby, the sulfide residue present on the wafer 2 can be measured easily with a good sensing accuracy in a short time on its manufacturing line.

Abstract: PURPOSE:To make it possible to set freely the opening diameter of a grid electrode to form an electron gun by providing circular openings to gear with the outer periphery of a core rod, and a pair of rectangular projections to gear with the outer periphery of the electrode, to a spacer. CONSTITUTION:Spacers 1 are used to insert the fourth grid 74 in a core rod while holding the fourth grid 74 from the upper side and the lower side. In this case, the positioning of the fourth grid 74 is set to gear the standard surfaces 3 and 4 of the spacer 1 and the standard surface of the fourth grid 74, making to unify the standard surfaces 3 and 4 of the spacer 1, circular openings 5, and the diameter of the core rod. As a result, the electrode of a large diameter can be assembled easily by using the spacers 1, and when the spacers 1 are removed, they can be removed easily in one direction, because they have been assembled by staggering their projections 2 each other. By such a constitution, a large diameter of grid electrode can be assembled easily without deteriorating the working efficiency and without reducing the accuracy.
