Title: Pattern forming method
Inventor: MATSUOKA KOJI
IPC: H01L21/027
Filed: 1995-03-20
Abstract: PURPOSE: To obtain stable line width control by a method wherein a dedicated area for detecting a resist development termination is provided on a wafer and light is projected to the dedicated area and reflected light from the resist and the wafer is detected to observe the development state of the resist, so that the data are fed back. CONSTITUTION: An exposed wafer 3 enters a processor 4 and a developing solution is dripped on the wafer 3. Simultaneously, light is projected from a light-casting part 1 to development termination detection pattern 3A located near the orientation flat of the wafer 3. Resist in an exposed area of the development termination detection pattern 3A is dissolved and the film thickness is gradually decreased, therefore the strength of light according to the variation of the resist film thickness is observed in a light-receiving part 2. A control unit 5 judges the time point when the amplitude is not observed from the waveform of the light strength, and computes the period after developing liquid is applied onto the wafer 3 until reaching the substrate. An instruction of the development termination period is sent to the processor 4 based on the obtained period.

Filed: 1990-03-13
Abstract: PURPOSE:To restrict a negative pressure within a garret spacing from being increased in the event that an air-tightness of air at the garret is higher than it is preset by a method wherein an air cleaner device is provided with a bypassing passage for guiding a part of air toward an air conditioner and a value device to close this bypass and releasing it when the air pressure in the garret becomes a negative pressure more than a specified value. CONSTITUTION:An air cleaner device A is comprised of some dust collecting elements 6 arranged in a main passage 5 of a housing 10, a bypass 7 bypassing the dust collecting elements 6 and a valve device 8 for opening or closing the bypassing passage 7. In the event that this air cleaner device A is arranged in a garret spacing 2 having a higher air-tightness than expected value, an amount of sucked air into the garret spacing 2 is poor against an amount of air blown from a blowing port 12 under an operation of a blower 4 and then an air pressure in the garret spacing 2 becomes negative further than the specified value in respect to an interior pressure. A valve plate 81 of the valve device 8 receiving this negative pressure releases an opening 93 against a compression coil spring 84 and further releases the bypass 7, resulting in that it is possible to restrict the negative pressure from being increased.

Abstract: PURPOSE:To alleviate thermal stress and to obtain a high power element by providing a grid shaped insulating layer or a layer whose conductive type is different from that of a substrate on the surface of the substrate, and linking a barrier metal which is independently formed in each grid with a flexible conductive layer. CONSTITUTION:P<+> diffused layers 14 (or insulating films) which are to become guard rings are provided on the surface of the N type Si substrate 2 in a grid shape. For example, a W electrode 3 which is to become the barrier metal is formed on each grid on the substrate surface so that metals are separated to each other. Then, after, e.g., an Ag film 15 is formed on the entire surface, a bump electrode 7 comprising, e.g., Ag is formed in the region on the substrate, on which the W electrode 3 is not provided, and the part other than electrode 7 is covered with an insulator. On the bottom surface of the substrate, an electrode comprising an Au layer 8 and an Ag layer 9 is provided. Thereafter, sealing is performed by glass, and a double heat sink type element is obtained. Since the barrier metal 3 is divided into the relatively small areas, the thermal stress can be reduced to a low value even though total area of the barriers is large, and the element suitable for the high power can be obtained.
