If you want to start off with a transparent layer without a background, click File > New > set background contents to "transparent", then OK. What you will get is an image that looks like a checker board - that's how Photoshop displays transparency. If you want to erase an existing background, then google for a tutorial like this "Photoshop tutorial extract image from background".
