    摘要: A sensor for measuring biopotential signals from the skin of a patient. The sensor comprises a carrier having a top surface positioned contiguous with the skin of the patient when the sensor is applied to the patient's skin and a bottom surface facing away from the patient when the sensor is applied to the patient's skin. The carrier has further plurality of spikes extending from the top surface for being inserted into the skin of the patient when the sensor is applied to the patient's skin. The sensor further comprises means for obtaining the biopotential signal and for making the biopotential signal available externally of the sensor. The carrier is manufactured of non-conductive material and the non-conductive material is made conductive to form electrical connection between the top and bottom surfaces of the carrier.

Also described is a product usable as a starting substrate for the manufacture of micro-electronic and/or micro-mechanic devices, including a flat substrate of a semi-conducting or conducting material, and having a first and a second surface and at least one electrically conducting member extending through the substrate. The electrically conducting member is insulated from surrounding material of the flat substrate by a finite layer of an insulating material, and includes the same material as the substrate, i.e. it is made from the wafer material.

    摘要: In manufacturing a pressure sensor a recess that will form part of the sensor cavity is formed in a lower silicon substrate. An SOI-wafer having a monocrystalline silicon layer on top of a substrate is bonded to the lower silicon substrate closing the recess and forming the cavity. The supporting substrate of the SOI-wafer is then etched away, the portion of the monocrystalline layer located above the recess forming the sensor diaphragm. The oxide layer of the SOI-wafer here acts as an “ideal” etch stop in the case where the substrate wafer is removed by dry (plasma) or wet etching using e.g. KOH. This is due to high etch selectivity between silicon and oxide for some etch processes and it results in a diaphragm having a very accurately defined and uniform thickness. The cavity is evacuated by forming a opening to the cavity and then sealing the cavity by closing the opening using LPCVD. Sensor paths for sensing the deflection of the diaphragm are applied on the outer or inner surface of the diaphragm. The monocrystalline diphragm gives the sensor a good long-term stability. Also the sensor path can be made of monocrystalline material, this giving the sensor even better good long-term characteristics. An increased sensitivity can be obtained by making active portions of the sensor paths freely extending, unsupported by other material of the pressure sensor, by suitable etching procedures.

    摘要: Micromachining, etching and bonding techniques are employed to fabricate hermetically sealed gas-filled chambers from silicon and/or glass wafers. The hermetically sealed gas-filled chambers have precise dimensions and are filled with a preselected concentration of gas, thus rendering exceptional performance for use as an optical gas filter. The first step involves etching one or more cavities or holes in one or more glass or silicon wafers. These wafers eventually become part of a chip assembly having one or more hermetically sealed gas-filled chambers after appropriate bonding procedures. Interfaces between aligned silicon wafers are bonded using fusion bonding techniques whereas interfaces between silicon and glass wafers are bonded using anodic bonding techniques. Bonding is accomplished in an over-pressured gas-filled bonding environment that contains a selected concentration of gas which is maintained at the bonding temperature in order to encapsulate a precise concentration of the gas within the micromachined cavity.
