A method for manufacturing a semiconductor device is provided. The method includes forming a semiconductor layer on a substrate. The first region of the substrate is expanded to push up the first portion of the semiconductor layer, thereby applying tensile stress to the first portion. The second region of the substrate is compressed to pull down the second portion of the semiconductor layer, thereby applying compressive stress to the second portion. An N type device is formed over the first portion of the semiconductor layer, and a P type device is formed over the second portion of the semiconductor layer.

An elongate bar having sliding handgrips concentrically mounted thereon adapted for use with a resistance-type exercise device. In a preferred embodiment, the bar has at least two, and more preferably four, axially oriented grooves in the outer surface thereof dimensioned to accommodate handgrip linking means therewithin. The handgrips, which are constrained to move only in an axial direction, are interconnected by linking means such as belts, in such a manner that the handgrips remain equidistant from the center of the bar throughout their axial range of motion. The interconnecting belts or cables are disposed to travel within the elongate grooves on the bar to provide the bar with a low profile. In the preferred embodiment, the linking means are belts that are supported by pulleys housed within recesses in the bar and rotatably attached thereto. The bar further includes resistive force attachment means operable for attaching weights, springs, cable(s), elastic bands or the like thereto to provide a resistive force. In a further embodiment, the bar includes floor supporting means and can be used for performing pushups. In yet a further embodiment, the bar includes wall attachment means and can be employed for performing pull-ups.

The rotatable push-up exercise device provides device for aiding a user in performing push-up type exercises. The device has a platform rotatably mounted on a base. The platform may selectively be held stationary or may be free to rotate when performing push-up exercises. The device includes a gripping bar mounted on the platform. The base is adapted to rest on a support surface, such as the floor. A pair of exercise devices are normally utilized together. In use the user grasps the gripping bar of each device with one hand and performs push-up exercises. Due to the rotation of the support surface with respect to the base, the user is forced to exercise the shoulders and other muscle groups in the user's body, in addition to the arm and chest muscles, in order to maintain a stable position.

An apparatus is disclosed for performing pushups thereupon. It includes a foot supporter coupled via a connecting means to a hand supporter. The foot supporter has front and back pieces pivotably coupled at a join via a double axle coupled by a short connector and a foot support bar comprising a crosspiece and support legs attached thereto. Therefore, the height of the crosspiece above said surface may be varied between a lowered position and a raised position. This device is compact and portable and is used for performing more effective push-ups.
