Abstract:
A method includes providing a wafer and providing a first spray bar spaced a distance from the wafer. A first spray is dispensed from the first spray bar onto a first portion (e.g., half) of the wafer. Thereafter, the wafer is rotated. A second spray is dispensed from the first spray bar onto a second portion (e.g., half) of the rotated wafer. In embodiments, a plurality of spray bars are positioned above the wafer. One or more of the spray bars may be tunable in separation distance and/or angle of dispensing.
Abstract:
In a wafer processing method and a wafer processing system, a first property on a back side of a wafer is measured. The back side of the wafer is supported on a multi-zone chuck having a plurality of zones with controllable clamping forces. The wafer is secured to the multi-zone chuck by controlling the clamping forces in the corresponding zones in accordance with measured values of the first property in the zones.
Abstract:
The present disclosure provides a method and apparatus for cleaning a semiconductor wafer. In an embodiment of the method, a single wafer cleaning apparatus is provided and a wafer is positioned in the apparatus. A first chemical spray is dispensed onto a front surface of the wafer. A back surface of the wafer is cleaned while dispensing the first chemical spray. The cleaning of the back surface may include a brush and spray of cleaning fluids. An apparatus operable to clean the front surface and the back surface of a single semiconductor wafer is also described.

Abstract:
This invention discloses a hair dye and a hair dyeing method using a dye mainly made of natural colors (used in food and cosmetics), synthetic colors (used in food and cosmetics), and cosmetic colors. The hair dye can be applied for dyeing hair and skin at the same time according to the keratin-like structure of the hair and skin. The hair dye can be manufactured in a form of a hair dye cream, a hair dye lotion, a frost hair dye, a hair dye gel, a hair dye ointment, a hair dye shampoo, a foam type hair dye, or a spray type hair dye. After the hair dye is combined with a perm agent, a dyeing and perming product is produced for dyeing and perming hair all at one time. The natural colors (used in food and cosmetics), synthetic colors (used in food and cosmetics) and cosmetic colors of the hair dye penetrate into the hair by different hair dyeing methods to achieve the hair dyeing effect, and permanent hair dye, semi-permanent hair dye and temporary hair dye are manufactured according to the depth that the color enters into the hair structure.

Abstract:
The present invention provides a method for forming a transistor having a stacked gate electrode structure with two gates; a lower floating gate and an upper control gate. The floating gate is formed of three polysilicon layers--undoped/doped/undoped polysilicon layers. A substrate is provided having a tunnel oxide layer 20. Then sequentially a first undoped, first doped, and second undoped polysilicon layers 22,24,26 are formed over the tunnel oxide layer thereby forming a lower floating gate layer 22, 24, 26. An intergate dielectric layer 28,30,32 is then formed over the second undoped polysilicon layer 26. Next, an upper control gate 36 and a cap oxide layer are formed over the intergate dielectric layer 28,30,32. The stacked two gate electrode structure is formed by patterning the above mentioned layers. Then spaced source and drain regions 44 are formed on opposite sides of the stacked gate structure thereby completing the transistor.
Abstract:
A method of semiconductor fabrication including providing a semiconductor wafer and dispensing a first chemical spray onto the wafer using a first nozzle and dispensing a second chemical spray using a second nozzle onto the wafer. These dispensing may be performed simultaneously. The method may further include moving the first and second nozzle. The first and second nozzle may provide the first and second chemical spray having at least one different property. For example, different chemical compositions, concentrations, temperatures, angles of dispensing, or flow rate. A chemical dispersion apparatus providing two nozzles which are operable to be separately controlled is also provided.
