摘要:
A surface of a compound semiconductor having at least gallium (Ga) and nitride (N) forms a target for sputtering with inert gas, so that oxide and other attachments are removed therefrom. The sputtering the surface is carried out until a disruption layer is formed which has atomically disordered and bumpy arrangement. Following the sputtering process, metal deposition by sputtering and alloying are carried out under vacuum in the same chamber used for the sputtering processes. As a result, the contact resistance between the surface layer and the deposited electrode layer is decreased.

This invention provides a window wiper of which the movement is not restricted and which is capable of wiping the entire surface of a windowpane, can be manufactured inexpensively, runs smoothly in any desired directions straight, and does not leave unwiped parts behind. The window wiper comprises a sticking unit 10 which sticks fast to a windowpane “W,” a wiping unit 20 which is mounted on the sticking unit 10 and wipes the windowpane “W,” and a running unit 30 which is mounted on the sticking unit 10 so that the former can turn freely. Accordingly, the running unit 30 can change its running direction without changing the posture of the wiping unit 20. Therefore, the corners of a windowpane too can be wiped clean by giving a shape with four corners to the wipe-off unit 22 of the wiping unit 20.

A projection type display apparatus that projects video onto a screen includes a liquid crystal panel using polymer-dispersed liquid crystal that disperses light when a voltage is applied and that transmits light when a voltage is not applied, being attached to an apparatus body 2 as a screen 1; and the video output from the apparatus body 2 is projected onto the screen 1 from the front side. Accordingly, there is provided the projection type display apparatus suitable for use in small space such as at home, in which a place for setting the apparatus is flexibly selected and the feeling of oppression is mitigated when the apparatus is not used.
