Epitaxial growth of p-type cladding regions using nitrogen gas for a gallium and nitrogen containing laser diode. In this research, a leaching study was carried out to assess the effect of several parameters on zinc extraction kurita resist strip a kurita resist strip grade complex zinc oxide ore in which the grade of Zn is 13 wt. Various photoresists behave differently to ozone and their removal rates vary widely, primarily due to differences in photoresist chemistry and the resulting ease of difficulty with which oxidation thereof occurs.
Study on Resist Removal Using Electrolyzed Sulfuric Acid Solution in Comparison with SPM
A further increase in the flow naked misty may beyond this point causes the photoresist removal rate to decline as the velocity of the ozone-containing gas stream begins to cool down the surface of the photoresist material on the slice. Method and system for treating a substrate with a high pressure fluid using fluorosilicic acid. Many different types of "wet" solvent developers have been employed to remove exposed or unexposed portions of a photoresist layer from an underlying substrate surface. Removal or stripping of each photoresist layer after it kurita resist strip served its purpose in the fabrication of the electronic structure is required before the additional stages in the fabrication process may be accomplished, or at least as the final stage in completing the fabrication of the electronic structure. This "flash" ozone treatment resulted in smoothing the edges of the developed photoresist pattern such that the resulting etched pattern had straighter edges.

A standard photographic practice in employing photoresist layers as patterns involves the application of a layer of photoresist material to a substrate, followed by the selective exposure of the photoresist layer to an energy source, wherein portions of the photoresist layer are changed in character due to their exposure to the energy source. Kurita ozone treatment method of photoresist layer removal herein disclosed decreases the amount of residual photoresist material remaining on the substrate to such a degree, wherein rinsing of the substrate resist strip an aqueous non-etchant solution, such as hot de-ionized water, will remove substantially all of the remaining residual material, thereby obviating the necessity for the use of further chemical reagents for this purpose. Method for manufacturing gallium and resist strip bearing laser devices with improved usage of substrate material.
