Abstract:
The present invention relates to space transformer for a probe card. Subject matters of the present invention are a method of manufacturing a space transformer for a polymer-based probe card and the space transformer for a polymer-based probe card manufactured by the same. The method of manufacturing a space transformer for a probe card comprises the following steps. In a first step, a glass substrate is prepared. In a second step, a mask pattern layer for forming a via-hole is formed on the glass substrate. In a third step, a substrate via-hole is formed on the glass substrate according to a set pattern of the mask pattern layer. In a fourth step, a conductive material fills the via-hole. In a fifth step, a polymer substrate is formed on the glass substrate, and a metal interconnection electrode, which is electrically connected to the substrate via-hole, is formed on the polymer substrate. In a sixth step, a second polymer substrate is formed on top of the polymer substrate, on which the metal interconnection electrode is formed, and a polymer substrate via-hole, which is filled with the conductive material, is formed on the second polymer substrate. And in the seventh step, polymer substrates resulted from the fifth and sixth steps are alternately stacked, and the metal interconnection electrode formed on the polymer substrate is electrically connected with the polymer substrate via-hole. According to the present invention, a conventional multilayer ceramic simultaneous sintering process is not adopted, and deformation of the space transformer due to contractions and expansions is thus prevented. Furthermore, a manufacturing yield as well as productivity are improved and a manufacturing cost is reduced.

The present invention relates to a method for manufacturing a nano-patterned metal film. In terms of a method for manufacturing a nano-patterned metal film, the method for manufacturing a nano-patterned metal film using a nano-imprint lithography and a plating process comprises: a first step where a resin layer is formed on the upper layer of a substrate; a second step where nano-pattern is formed on the resin layer by an imprinting and a hardening process after locating a stamp for imprinting on the resin layer; a third step where a seed layer is vapour-deposited on the nano-patterned resin layer; a fourth step where a metal layer is formed on the seed layer by a plating process; and a fifth step where a nano-patterned metal film is produced by separating the seed and metal layers from the substrate after removing the resin layer. Hence, the present invention uses a nano-imprint lithography and a plating process which reduces cost and time for processing by simplifying the processes. Also, a nano-patterned metal film can simply be produced.

PURPOSE: A vibrating membrane and a back plate of a capacitance type microphone based on a MEMS(Micro Electro Mechanical System) and a method for manufacturing the same are provided to prevent oxidation due to external humidity by forming an insulating layer on the vibrating membrane and the back plate. CONSTITUTION: A first insulation layer is formed on the upper part of a substrate(101). A vibrating membrane(102) forms a second insulation layer on the top of a first metal layer. A sacrificial layer for an air gap is formed on the upper part of the vibrating membrane. An external surface of the sacrificial layer is patterned by a photolithography process. A third insulation layer is formed on the upper part of the patterned sacrificial layer. A second metal layer is formed on the upper part of the third insulation layer. An upper conductive line is formed on the patterned second metal layer. A fourth insulating layer is formed on the upper part of a second metal layer. A back plate is obtained by the photolithography process. A sound inlet hole and a vibration hole are formed.
