    摘要: The present invention relates to a light emitting diode with high luminance and method for making the same, and more particularly to a light emitting diode having a transparent window layer which is formed by a semiconductor film of nitrogen-containing compounds. The present invention is mainly directed to growing a window layer of a light emitting diode with a nitrogen-containing compound on the double heterostructure of InGaAlP. Since the energy gap of the nitrogen-containing compound is greater than that of the light emitted from the active layer and is smaller than that of GaP, it is easily to be doped and to form metallic ohmic electrode. Therefore, it is suitable to form a window layer, thereby increasing the light emitting efficiency of a light emitting diode. In addition, the nitrogen-containing compounds can be formed by the current MBE or OMVPE techniques. Therefore, the light emitting diode can be mass-produced and does have industrial applicability.

    摘要: A thin film transistor includes a substrate and an active layer formed on the substrate. The active layer includes a channel region, a source region and a drain region. A source electrode and a drain electrode are formed on the source region and the drain region respectively. A gate insulating layer is formed between a gate electrode and the channel region. The thin film transistor further includes a nitride conductive layer formed between the drain electrode and the drain region, and between the source electrode and source region. The nitride conductive layer has a carrier concentration higher than that of the active layer, thereby reducing contacting resistances between the drain electrode and the drain region and between the source electrode and source region.

    摘要: A novel method of using rapid variation of temperature for generating driving energy to activating P-type compound semiconductor films and reducing the resistivity thereof. The P-type compound semiconductor films are made from III-V nitrides or II-VI group compounds doped with P-type impurity. In addition, the time duration when the ambient temperature is greater than a certain temperature during the annealing process is limited to be less than one minute. Therefore, the optoelectronic performance of the P-type compound semiconductor films will not degrade because the duration of annealing process is decreased.
