IPC: H01L21/336
Filed: 1993-02-04
Abstract: PURPOSE:To provide a semiconductor device in which the resistance of a wiring can be reduced by forming a gate electrode in th structure of a complex layer in which a layer made of pure aluminum is arranged under an aluminum layer to which a metal of high melting point is added. CONSTITUTION:An aluminum film 2 is formed on a glass substrate 1, and thereon is so formed by a direct-current sputtering method as to be overlapped an aluminum film 3' to which tantalum of 2 atomic % a high-melting-point metal is added, and then the work of photolithographic technique is applied thereto to form a gate electrode G of a first conductive layer. The whole of the aluminum layer 3' is anodized to form an oxide aluminum gate insulating layer 3 for an insulating layer, and then a second gate insulating film 4, an amorphous silicon semiconductor layer 5 and an amorphous silicon semiconductor layer 6 containing phosphorus are sequentially formed. Therefore, since the first semiconductor layer is covered with an insulating film containing an anodizable high-melting-point metal as an impurity in aluminum, a hillock can be prevented, so that the increase of the resistance of a wiring may be controlled.

Title: Lens holder
Inventor: ISAKI MASATAKA
IPC: G02B7/02
Filed: 1987-01-28
Abstract: PURPOSE:To improve adjusting accuracy and workability and to reduce the number of adjusting processes by providing a lens holder with an exciting means for exciting a lens barrel in an optical axis direction and a fixing means for driving a rack gear for a locking chip, moving and adjusting the lens barrel in the optical axis direction and then fixing the locking chip on an outer frame so as not to move it. CONSTITUTION:At the time of back focus adjustment, an adjusting jig 24 is prevented from being played by rotating the jig 24 against the exciting force of a compression spring 27 and the lens barrel 15 is moved in the optical axis 16 direction in accordance with the movement of the locking chip 19. Since the relation of the rotational angle of the jig 24 to the moving distance of the lens barrel 15 corresponds to the engaging relation between a pinion gear 26 and the rack gear 22, both the values are directly proportional to each other. When a fixing screw 21 is completely clamped after said adjustment and the locking chip 19 is fixed, the lens barrel 15 is excited in the optical axis 16 direction by the exciting force of the compression spring 27 and positioned on the outer frame 11 without generating play in the optical axis direction. After removing the jig 24, the back focus adjustment of the lens system can be completed.
