SEMICONDUCTOR INTEGRATED CIRCUIT AND ITS FABRICATION |
| 摘要 |
A method for fabrication of metal to semiconductor contacts results in sloped sidewalls in contact regions. An oxide layer is deposited and etched back to form sidewall spacers. A glass layer is then deposited and heated to reflow. After reflow, an etch back of the glass layer results is sloped sidewalls at contact openings and over steps. |
