摘要:
This disclosure enables high-productivity fabrication of porous semiconductor layers (made of single layer or multi-layer porous semiconductors such as porous silicon, comprising single porosity or multi-porosity layers). Some applications include fabrication of MEMS separation and sacrificial layers for die detachment and MEMS device fabrication, membrane formation and shallow trench isolation (STI) porous silicon (using porous silicon formation with an optimal porosity and its subsequent oxidation). Further, this disclosure is applicable to the general fields of photovoltaics, MEMS, including sensors and actuators, stand-alone, or integrated with integrated semiconductor microelectronics, semiconductor microelectronics chips and optoelectronics.
摘要:
High productivity thin film deposition methods and tools are provided wherein a thin film semiconductor material layer with a thickness in the range of less than 1 micron to 100 microns is deposited on a plurality of wafers in a reactor. The wafers are loaded on a batch susceptor and the batch susceptor is positioned in the reactor such that a tapered gas flow space is created between the susceptor and an interior wall of the reactor. Reactant gas is then directed into the tapered gas space and over each wafer thereby improving deposition uniformity across each wafer and from wafer to wafer.

A method of manufacturing a semiconductor device includes the steps of forming a plurality of first integrated circuits on the surface side of a first semiconductor substrate; forming a plurality of second integrated circuits in a semiconductor layer that is formed on a release layer provided on a second semiconductor substrate; bonding the two semiconductor substrates so that electrically bonding portions are bonded to each other to form a bonded structure; separating the second semiconductor substrate from the bonded structure at the release layer to transfer, to the first semiconductor substrate, the semiconductor layer in which the plurality of second integrated circuits are formed; and dicing the first semiconductor substrate to obtain stacked chips each including the first integrated circuit and the second integrated circuit.

Provided is a method for transferring, onto a second substrate, at least one of functional regions arranged and joined to a first separation layer that is disposed on a first substrate and that becomes separable by a treatment, in which regions on the second substrate where the functional regions are to be transferred have a second separation layer that becomes separable by a treatment. The method includes a step of joining the first substrate to the second substrate by bonding such that the functional regions contact the second separation layer; a step of separating the functional regions from the first substrate at the first separation layer; and a step of, before or after the step of separation, forming separation grooves penetrating through the second substrate and the second separation layer from a surface of the second substrate, the surface being opposite to a surface having the second separation layer thereon.

A method includes arranging a bonding layer of a predetermined thickness on at least one of a first functional region bonded on a release layer, which is capable of falling into a releasable condition when subjected to a process, on a first substrate, and a region, to which the first functional region is to be transferred, on a second substrate; bonding the first functional region to the second substrate through the bonding layer; and separating the first substrate from the first functional region at the release layer.
摘要:
Germanium circuit-type structures are facilitated. In one example embodiment, a multi-step growth and anneal process is implemented to grow Germanium (Ge) containing material, such as heteroepitaxial-Germanium, on a substrate including Silicon (Si) or Silicon-containing material. In certain applications, defects are generally confined near a Silicon/Germanium interface, with defect threading to an upper surface of the Germanium containing material generally being inhibited. These approaches are applicable to a variety of devices including Germanium MOS capacitors, pMOSFETs and optoelectronic devices.
