    Abstract: s wird ein Verfahren zur Herstellung eines Halbleiterbauelements mit einem Halbleitertrager (1) vorgeschlagen, bei welchem fur die Ausbildung von frei tragenden Strukturen (3) fur ein Bauelementeine flächige poröse Membranschicht (3) und eine Kavität (2) unter der porösen Membranschicht (3) erzeugt wird. Die Erfindung hat die Aufgabe, eine Membranbeschädigung bei der Herstellung oder bei regelmässig auftrenden Anwendungsfällen zu vermeiden. Diese Aufgabe kann durch unterschiedliche Vorgehensweisen gelöst werden. Bei einer ersten Lösung erhält der Halbleiterträger (1) im Membranbereich im Vergleich zur Kavität eine unterschiedliche Dotierung, womit sich unterschiedliche Porengrössen und/oder Porositäten herstellen lassen, was bei der Kavitätserzeugung fur einen verbesserten Ätzgastransport genutzt werden kann. Die Aufgabe kann jedoch auch dadurch gelöst werden, dass im Membranbereich Mesoporen und im späteren Kavitätsbereich Nanporen als Hilfsstruktur erzeugt werden. Im Weiteren wird unter anderem ein Halbleiterbauelement vorgeschlagen, das auf einem oder mehreren dieser Verfahren basiert.

    Abstract: A method for providing a conductive ground plane beneath a suspended microstructure. A conductive region is diffused into a substrate. Two dielectric layers are added: first a thermal silicon dioxide layer and then a silicon nitride layer. A first mask is used to etch a ring partially through the silicon nitride layer. Then, a second mask is used to etch a hole through both dielectric layers in a region having a perimeter that extends between the inner and outer edges of the ring. This leaves the conductive region exposed in an area surrounded by a ring that has the silicon dioxide layer and a narrow silicon nitride layer. The ring is surrounded by an area in which the silicon dioxide and silicon nitride layers have not been reduced. A spacer silicon dioxide layer is deposited over the dielectric and then a polysilicon layer is deposited and formed into the shape of a suspended microstructure. When the spacer layer is etched away, the silicon dioxide under the narrow silicon nitride layer is removed, along with the narrow silicon nitride layer, leaving an exposed ground plane surrounded by a dielectric with minimal undercutting.

    Abstract: A wafer for use in a MEMS device having two doped layers surrounding an undoped layer of silicon is described. By providing two doped layers around an undoped core, the stress in the lattice structure of the silicon is reduced as compared to a solidly doped layer. Thus, problems associated with warping and bowing are reduced. The wafer may have a pattered oxide layer to pattern the deep reactive ion etch. A first deep reactive ion etch creates trenches in the layers. The walls of the trenches are doped with boron atoms. A second deep reactive ion etch removes the bottom walls of the trenches. The wafer is separated from the silicon substrate and bonded to at least one glass wafer.
