Title: On channel agile FM demodulator
Inventor: MARZ DANIEL
IPC: H03D3/02
Filed: 1991-04-26
Abstract: An on channel frequency agile PLL demodulator is provided using a precise and stable oscillator (82), such as a VCXO having its output frequency variable over a limited range. The output of the oscillator is multiplied (84) by a multiplication factor to produce a mixing frequency. The multiplication factor scales the limited range of the oscillator to produce a proportionate mixing frequency deviation. A frequency synthesizer (90) is used to enable the demodulator to detect signals on different channels. In one embodiment, the output of the frequency synthesizer (90) is mixed with the scaled oscillator output to provide a mixing frequency (fn) having a fixed deviation for all channels.

Title: A method for preparing masks for use in the manufacture of a semi-conductor IC wafer, and a combination of masks
Inventor: THOMPSON JAMES
IPC: G03F1/00
Filed: 1997-08-26
Abstract: A method for preparing a set of masks for forming an IC wafer minimises the set-up required for setting up an automated critical dimension scanning electron microscipe. The masks of size to form one field (3) of a plurality of fields (3) in the respective layers of the IC wafer. Each mask is provided with an alignment forming area for forming identical alignment area (11) in each field (3) of the layer at identical locations from an origin (12) of the respective fields. Critical dimension test forming features n the masks form test features (31) in test areas (26) the diemensions of which may be measured for facilitating a determination of the critical diemsnions of components the critical dimensions of which are to be measured. The test areas (26) are located in identical locations in each field (3) in each layer and identical location in each field (3) in each layer and identical test features (31) are located in identical locations in their corresponding fields (26). The X and Y coordinates of each test feature (31) at which the critical dimension of the test feature (31) is to be measured is stored in software with reference to a reference point (29) of the corresponding test area (26), and the X and Y coordinates of the reference points (29) with reference to the origin (12) are also stored in software. Thus, computation of the X and Y coordinates of the locations at which the test features (31) are to be measured can readily easily be computed as the masks are being prepared, and stored in software, ready for down loading into the automated critical dimension scanning electron microscope during the set up of the microscope. The alignment areas (11) define alignment points (14) at identical locations, and the X and Y coordinates of one of the alignment points (14) from its corresponding origin (12) is stored in software for down loading into the automated critical dimension scanning electron microscope during set-up of the microscope. <Figs. 1 and 2 are to accompany the Abstract>.
