Integrated device based upon semiconductor technology, in particular chemical microreactor
First Claim
1. A method of performing a biological test, comprising applying a biological fluid to an integrated device including:
- a) a semiconductor body having a first portion, a second portion, and a mid-portion positioned between the first and second portions;
b) a hydraulic circuit including an inlet fluidly connected to a buried channel positioned in the first portion of the body, fluidly connected to an outlet positioned in the second portion of the body;
c) a heating element positioned in the first portion of the body and thermally linked to the buried channel;
d) a heat dissipator positioned in the mid-portion of the body and thermally linked to the outlet to substantially block propagation of heat from the heating element to the second portion of the body; and
e) a sensing electrode positioned in the outlet;
whereby said biological fluid is tested in the buried channel and the results of the test are sensed at the sensing electrode.

Abstract
An integrated device based upon semiconductor technology, in particular a chemical microreactor, including a semiconductor body having a high-temperature operating portion and a low temperature operating portion. The semiconductor body is provided with a thermal-insulation device including a dissipator element arranged between the high-temperature operating portion and the low-temperature operating portion. The dissipator includes a membrane connecting the high-temperature operating portion and the low-temperature operating portion, and a plurality of diaphragms that extend substantially orthogonal to the membrane and are parallel to one another.
