Title: Measuring electrical potential of single biological cell in nutrient, optionally carrying out micromanipulations
Inventor: BAUMANN WERNER
IPC: C12N15/89
Filed: 1998-06-23
Abstract: A cell (3) rests on a carrier (21). An opening is made through the cell membrane within the resting area (5), away from the edge of the carrier. The measurement is taken through this opening. An Independent claim is also included for the corresponding apparatus. Additional points noted include adherent cell sealing to the surface, an internal cell probe connected to an amplifier and insulated from the surrounding resting area, and a poration tool in the resting area. Preferred Features: Cell potential is measured through the opening, being the electrical potential between cell fluid and nutrient. Electroporation, mechanical impulse or focused ultrasound makes the opening. Several ultrasonic waves are superimposed additively, increasing amplitude at the opening point. Penetration results from laser radiation, or a chemical substance. A substance activated electrically, chemically and/or by radiation and/or an electrical field, makes the opening. Reduced or excess pressure is applied. Suction fixes the cell to the resting area (5). Following opening, cell fluid may be extracted for investigation. Intracellular manipulation takes place through the hole. Medicament and/or foreign material and/or a biological substance may be introduced into the cell. Salient features of the preferred apparatus include a reference electrode. The poration electrode, its operation and association with a semiconductor forming a switch, are further described. Actuation and control are elaborated.

Title: Vertical DMOS transistor
Inventor: VIETZKE DIRK
IPC: H01L29/08
Filed: 1999-06-25
Abstract: The DMOS transistor has a pedestal zone (11) located under the transistor. In the surface of silicon semiconductor substrate (1), in addition to doping material for the buried layer (3), more doping material is brought in for the pedestal zone. It is brought in before the deposit of epitaxial layer (2). For example, Arsenic or antimony is used for the buried layer the phosphorus is used for the pedestal zone.  The phosphorus diffuses quicker than the arsenic or antimony, so the pedestal zone forms in addition to the buried layer. It develops during a temperature procedure, which takes place after deposition of the epitaxial layer.
