I belive this what your looking for it called a Topspin-Slice First Serve.. There it is...
The topspin-slice serve is the most common first serve used at the intermediate and advanced levels in tennis. As the name implies, it uses a combination of topspin and slice (which on serves is sidespin, not backspin). The topspin increases the margin of error over the net, the height of the bounce, and the effective speed of the serve (by decreasing deceleration on the bounce). The slice makes the ball curve to the left (for right-handed servers). The topspin-slice serve can generally be hit with the most power of any of the spin serves. This serve is often called a "slice serve," which causes an unnecessary confusion with the pure slice serve that only has sidespin.
Key points:
* Stance: Stand with your right foot parallel to the baseline and your left foot pointing roughly toward the right net post.
Grip: Use a Continental grip, holding the racquet loosely enough that it will pivot in your hand as you close your outer fingers just before meeting the ball.
* Toss: Hold the ball in your fingertips. Start the ball and racquet in front of the midline of your body and below your waist, with your hands fairly close together. Toss by moving the ball diagonally upward and forward in a straight line toward the point of contact. Release the ball with your left hand as high as possible (could have been higher here) and reaching toward the released ball.
* Wind-up: Start the racquet back as you begin the toss. The wind-up can add power to your serve, but its contribution is secondary to a set of more essential factors. The full, classic wind-up is no longer considered necessarily best for everyone. Some of the most powerful servers in tennis use a much-abbreviated wind-up, and a few very good servers find themselves more comfortable using no wind-up at all. Most players can use a wind-up without compromising other factors, and as long as you don't come to a complete stop just before swinging up at the ball, you will probably deliver a harder serve than you would without a wind-up.
* Swing: The key to a powerful service swing that doesn't strain your arm is to translate the power from the upward and forward thrust of your legs and the uncoiling of your trunk into an upward whipping motion of a loose arm. Particularly important are a loose wrist and a full bending of the elbow. Don't try deliberately to "snap your wrist" on the serve. If your wrist is loose and the rest of your swing is sound, your wrist will whip forward at exactly the right moment. A deliberate snap out of sync with the rest of the swing can injure your arm. Failing to bend your elbow fully will diminish your power and eventually wear out your shoulder.
* Point of contact: Meet the ball at the full upward extension of your reach, 1-2 feet to your right, and 1-2 feet in front of yourself, as measured by where your head is at the time of contact. Where you toss the ball will be influenced by how much you lean forward and how much you jump upward before swinging.
* Striking the ball: Strike the ball diagonally upward and to the right, from its center toward what would be 1:30 on its face if it were a clock. The upward part of this racquet path creates topspin; the rightward part, slice.
* Follow-through: Follow through to the left side of your body (for right-handers). The forward and upward thrust of your legs and the uncoiling of your trunk at the beginning of this service motion should result in your naturally stepping into the court and roughly facing the left sideline after contact.
