Latest Patents

David A Spear holds a patent for a semiconductor device manufacture. This patent describes a technique for achieving a substantially planar structure that incorporates embedded vapor phase epitaxial growth. The method involves using a window-frame shaped mask of epitaxial growth resistant material to define a well for embedded growth. This approach also addresses mask registration issues during the selective removal of unwanted material that has been epitaxially grown on regions surrounding the well. Additionally, complementary format structures can be formed, allowing for epitaxial growth up the sides of a mesa to reach the same height as the material grown on top of the mesa itself. He has 1 patent to his name.
