  • Patent number: 6475317
    Abstract: The present invention provides a method for manufacturing an electronic component of laminated ceramics such as a laminated ceramic capacitor in which, when a ceramic paste is applied on a ceramic green sheet in order to substantially eliminate steps caused by the thickness of a film of inner circuit elements such as an inner electrode, the ceramic paste is prevented from generating a gap between the paste and the film of inner circuit elements, or the thickness of the ceramic paste is prevented from being increased, by allowing the paste to overflow the film of inner circuit elements, even when the application position has been a little shifted, wherein an inclined face is formed at the periphery of an inner electrode that serves as the film of inner circuit elements, the ceramic paste being applied so as to overlap the periphery of the inner electrode, and wherein the used ceramic paste contains about 40% by weight to 85% by weight of solvents in order to facilitate smooth leveling of the applied ceramic pa

  • Patent number: 6475281
    Abstract: An applicator for one of direct and indirect application of a coating medium onto a traveling fiber material web includes at least one dosing device and a coating edge delimiting device. The at least one dosing device includes a pair of lips with each lip having a free end adjacent the fiber material web and extending transverse to a direction of travel of the fiber material web. Further, the lips define a dosing slot therebetween. The dosing slot is an open-jet nozzle and has two side edges. The coating edge delimiting device includes at least two coating edge delimiting elements fitted between and in direct contact with each of the lips. The coating edge delimiting elements close off and substantially seal the dosing slot on the side edges, thereby substantially sealing the dosing slot. Each coating edge delimiting element has a wall section extending beyond the free ends of the lips in a flow direction of the coating medium through the dosing slot.

  • Patent number: 6464789
    Abstract: A cooling processing unit for cooling a wafer to a predetermined temperature is disposed between a heat processing unit and a set of a resist coating processing unit and a developing processing unit. Pre-cooling units are stacked in multi-stages on top of the cooling processing unit. Immediately after having undergone heat processing in the heat processing unit, the wafer is first transferred to the pre-cooling unit by a first transfer machine. Thereafter, the wafer is transferred to the cooling processing unit by a third transfer machine to be cooled to the predetermined temperature, and then transferred to the resist coating processing unit by a second transfer machine. Thus, over-bake of the wafer can be prevented.

  • Patent number: 6423140
    Abstract: The invention is related to the formation of three different and repeated stripes abbreviate as ABCABC-typed or A_B_C-typed at the die exit. The symbol, “_”, implies that there is no coating between two adjacent stripes. In this invention a guide shim and a guide die are inserted between two coating dies. Three different coating solutions will flow into the die assembly through different inlet positions. Two of which are introduced from the two coating dies will flow through the multiple channels provided in the guide shim and the guide die respectively and then contact with each other and with the third solution introduced from a side of the guide die in the same slot section to form the ABCABC-typed stripes. The coating solutions can also flow through the multiple channels to the same slot section but not contact each other to form the A_B_C-typed stripes at the die exit with a modification of the die assembly.

  • Patent number: 6372042
    Abstract: A photo process system for semiconductor wafers prevents air from flowing across the top of a baking region to produce a stable downward laminar air flow in front of baking units disposed at several levels in the baking region. The baking region is located on one side of a housing, and a coating unit for coating a wafer with a photoresist is located on the other side of the housing. The housing has a clean air entrance and air filters at an upper portion thereof, and a clean air discharge opening at the very bottom thereof. An air flow containment dam prevents clean air entering the housing from flowing horizontally at the top of the baking region. Such a horizontal flow of air would otherwise produce turbulence severely affecting the ability of the air to flow downward across the front of the baking units and toward the discharge opening as a laminar air flow. The laminar air flow hardly passes into the baking units and thus, hardly induces temperature variations in the coated wafers that are being baked.
