Patent EP-0660184-A2 (EP)
Inventor: BRUNNER TIMOTHY ALLAN
IPC: G03F1/30

Abstract: Selective deposition of silica from a liquid phase solution of silica in hydrofluorosilicic acid through openings in a pattern of polyimide or similar organic material provides an optically improved phase shift mask structure for making lithographic exposures since deposition can be made substantially anisotropic to yield deposits of substantially uniform thickness. Deposition from the liquid phase is readily controlled and highly predictable control of deposition rate can be achieved by control of temperature of a low temperature deposition process. Therefore the optical quality of the mask need not be compromised by other structures, such as etch stop layers, otherwise necessary to achieve high phase shift accuracy and the deposits of phase shift material are substantially homogeneous. The process of deposition from the liquid phase can be stopped and started at will and the mask can be fabricated by a process which is substantially free from material-dependent or material-based process restrictions. The index of refraction of the deposited material can also be adjusted by annealing. More specifically, a substrates (30) is coated with, in order, an optional conductive thin film (32), an opaque mask material (34), a relatively thick polyamide layer (36), a barrier dielectric layer (38), and a resist layer (40) then, these layers above the conductive thin film are patterned in accordance with the desired pattern of opaque material in first regions (20) and the central feature shape in second region (10) for the particular type of rim phase shift mask structure illustrated herein. The remaining resist is removed during RIE of the polyamide and the barrier dielectric is then etched away by a CF 4  plasma etch and regions of the mask which are to have 0° relative phase shift are mask by depositing and patterning a first resist pattern (42). Next, an oxide layer (44) is deposited on the unmaksed regions of the substrate to an arbitrary depth corresponding to a desired amount of phase shift. These regions (44) are masked with a further deposition and patterning of a layer of resist (50). Finally the mask in accordance with the invention is then completed by stripping of the polyamide and polyamide. This completed mask alternates opaque regions with transparent regions of three different optical path lengths in first region (20).

Abstract: The chemical dry cleaning assembly, for clothing has a throttle (9) in the air recirculation system between the fan (7) and the cooling register (11). A gas measurement and control system (23) is connected to the temp. monitor (25) in the air flow (5) at the outlet side (3) of the drum (1), and to a pressure monitor (27), also with a link to the heating register (13). The heating register (13) is switched on and off according to the air flow (5) temp. and the throttle (9) is activated. A monitor (41) in the drum (1) gives a non-contact measurement of the temp. of the material being processed and is connected to the gas measurement and control (23) system. A controlled water contact unit (31) delivers water (45) to the drum (1) through a drying control (17) between the drum (1) and it. Also claimed is a control operation where the air flow vol. is constantly varied according to the concn. of solvent vapour in the air flow, taken at least from the temp. and pressure of the air flow at the outlet side of the drum. The temp. at the inlet side of the drum is lowered if the outlet temp. is higher than a set value. The temp. of the material being processed is measured without contact. When the material temp. rises, the heating register is disconnected and the cleaning process is stopped when the gas concn. in the air flow drops by more than a given value. Water pptd. from the air flow is caught before the cooling register, and returned to the processed material as a vapour in the drum when the air moisture content of the material drops below a certain value. The air moisture content is measured as well as the temp. and pressure. <IMAGE>

Abstract: An attenuating phase-shifting optical lithographic mask is fabricated, in a specific embodiment of the invention, by first depositing a uniformly thick molybdenum silicide layer (11) on a top planar surface of quartz (10). The molybdenum silicide layer has a thickness sufficient for acting as an attenuating (partially transparent) layer in a phase-shifting mask. A uniformly thick chromium layer (12) is deposited on the molybdenum silicide layer. The chromium layer has a thickness sufficient for acting as an opaque layer in the phase-shifting mask. Next, the chromium layer is patterned by dry or wet etching, while the chromium is selectively masked with a first patterned resist layer (13). Then the molybdenum silicide layer is patterned by dry or wet etching, using the resulting patterned chromium layer as a protective layer, whereby a composite layer of molybdenum silicide and chromium is formed having mutually separated composite stripes (31, 32). Any remaining resist is removed. Next the top and sidewall surfaces of some, but not others, of these mutually separated stripes are coated with a second patterned resist layer (15). Finally (FIG. 6), the chromium layer, but not the molybdenum silicide layer, is removed from the others of the mutually separated composite stripes.

Date Jun. 13, 1996In a mobile communication system, two or more parallel traffic channels are allocated for high-speed data transmission over the radio path. Different channel numbers are assigned to these parallel traffic channels for the duration of the connection. The data of a high-speed data signal is inserted at the distribution point of the transmission end into frames each of which is provided with a channel number indicating the parallel traffic channel used for the transmission. The frames transmitted in a traffic channel always contain the same channel number during the whole call. The frames are divided into parallel traffic channel in the sequential order according to the channel numbering. At the reception end the data contained in the frames is reassembled into a high-speed data signal in the sequential order according to the channel numbers in the frames. Frame numbering may be used within each of the traffic channels so that at least two successive frames always have a different frame number. Consequently, the allowed delay offset between the traffic channels will increase with the number of the frame numbers, and the order of the frames will be maintained under any circumstances.
