Abstract: A method of fabricating a HEMT includes the following steps. A substrate having a group III-V channel layer, a group III-V barrier layer, a group III-V gate layer, and a gate etch stop layer disposed thereon is provided. A passivation layer is formed to cover the group III-V barrier layer and the gate etch stop layer. A gate contact hole and at least one source/drain contact hole are formed in the passivation layer, where the gate contact hole exposes the gate etch stop layer, and the at least one source/drain contact hole exposes the group III-V channel layer. In addition, a conductive layer is conformally disposed on a top surface of the passivation layer and in the gate contact hole and the at least one source/drain contact hole.

Abstract: A flash memory storage apparatus is provided. The flash memory storage apparatus includes a substrate, a control and storage circuit unit, a ground lead, at least a signal lead, and a power lead. The control and storage circuit unit, the power lead, the signal lead, and the ground lead are disposed on the substrate, in which the power lead, the signal lead, and the ground lead respectively electrically connect to the control and storage circuit unit. Moreover, the flash memory storage apparatus further includes an extra ground lead electrically connected to the ground lead or a protrusion on the substrate, such that the ground lead first electrically connects to a host when the flash memory storage apparatus is plugged into the host.

Abstract: A compact card reader is described. The compact card reader has a charging circuit and a cellular phone-connecting slot to enable the compact card reader to save/retrieve data to/from a memory card or a cellular phone, at the same time charge the cellular phone and the cellular phone battery in order to reduce the operation cost and this also increases the speed of the data processing.
