Dustproof structure of image generation device, and projection display device

The method of manufacturing a semiconductor device selectively forms a resist film on the multilayer gate film and the gate side wall insulating film extending on the semiconductor substrate. An upper part of the gate side wall insulating film and the hard mask film selectively are removed by etching using the resist film as a mask so as to expose a surface of the metal film. the metal film and the barrier metal film adjoining the metal film are removed, by wet etching. After the removal of the resist film, embedding a space formed by removal of the metal film and the barrier metal film and depositing a pre-metal dielectric to a level higher than an upper surface of the remaining hard mask film. A top part of the pre-metal dielectric is planarized by CMP using the remaining hard mask film as a stopper.

A projection display device projects light modulated based on a video signal. The projection display device includes a light source, a first fan for cooling the light source, and a second fan different from the first fan. The number of revolutions of the first fan is increased or decreased with the increase or decrease of the output of the light source. The number of revolutions of the second fan is decreased when the number of revolutions of the first fan is increased, and increased when the number of revolutions of the first fan is decreased.

Projection display device comprising a light source

Provided is a projection type display device that has dust-proof and coolable optical components. According to an aspect of the present invention, the display device includes a case, a dust-proof structure that has a plurality of walls surrounding a plurality of optical components to prevent dust, and which is located in the case, and suction ports (and') formed in the case and configured to suck cooling air along one wall of the dust-proof structure to cool the optical components. The suction ports are separated into first suction port () and second suction port (&#x2032;) with a position of one wall set as a reference. First suction port () is located to blow the cooling air to the dust-proof structure, while second suction port (&#x2032;) is located to prevent direct blowing of the cooling air to the dust-proof structure. An area of first suction port () is smaller than that of second suction port (&#x2032;).
