Title: Etching of pattern in or through glass layers - uses thin nickel layer directly on glass and photoresist on top of this to provide improved adhesion and etch resistance
Inventor: GOEBEL HERBERT DIPL PHYS DR
IPC: C03C15/00
Filed: 1990-06-06
Abstract: Glass substrates (10) are etched, using a masking layer, in HF containing etchant. The feature is that the masking layer is a double layer with a thin Ni layer (20), pref.  evaporated and annealed, in contact with the glass (10) and at least one photo resist layer (21) on the Ni-layer. A pattern is defined in the photo resist layer using a photographic process and developing. The Ni layer is removed in the areas where the photo resist layer has been removed, pref. using a wet etching step. The glass is etched, either partially or through to the outer surface, and afterwards the masking layers are removed, pref. in a single step using e.g. fuming nitric acid. The glass substrate can be a glass panel, with or without a structure, or a glass coated Si substrate. Several structures can be etched at the same time. USE/ADVANTAGE - The process combines the improved adhesion of the photo resist layer through the use of a Ni-layer and the reduced pinhole density possible by the use of the photo resist layer. The resulting double layer is resistant to HF etchant for the duration of the etch process through a 0.1mm thick glass panel. The structures produced can be used for the assembly of sensors, e.g. by gluing to a Si-based sensor or for thin film applications.

Patent DE-4041484-A1 (DE)
Inventor: STOLTE JOHANNES
IPC: H04N9/29
Filed: 1990-12-22
Abstract: 2.1. In HDTV sets having a 16:9 picture tube, it is required to completely switch off the decayed demagnetisation current by means of a relay. It is known to control the relay from the secondary side of the switched-mode power supply. The relay contact is then on the mains-connected hot side and the relay winding is on the mains-isolated cold side of the switched-mode power supply. A relatively expensive relay must therefore be used which has a dielectric strength according to VDE. It is the object to modify the circuit in such a manner that a relay can be used which does not have any special requirements for dielectric strength. 
<??>2.2. The relay winding (A) is connected in series with the primary operating winding (5) of the switched-mode power supply and is bypassed by an NTC resistor (14). 
<??>2.3. Particularly for television sets with a 16:9 picture tube.
